Always be familiar with chain block operating controls, procedures and warnings.
Always allow only competently trained people to operate the hoist.
Always operate a hoist only if you are physically fit.
Always inspect the hoist before use (Refer to Chapter 5).
Always let the authorized personnel inspect the hoist periodically (Refer to Chapter 5).
Always make sure the chain block suspension hook is securely attached to a suitable support. The selection and calculation
of the appropriate supporting structure are the responsibility of the operating company.
Always maintain a firm footing or be otherwise secured when operating the chain block.
Always make sure that load slings or other approved sling attachments are properly sized and seated in the hook saddle.
Only approved and certified lifting tackle must be used.
Always make sure that the hook latch, is closed and not supporting any part of the load.
Always make sure that the load is free to move and will clear all obstructions.
Always take up slack chain carefully, check load balance, then lift a few centimetres and check to be sure the brake will hold
the load and that attachments to the load are firmly seated.
Always avoid any swinging of the load or load hook.
Always protect load chain from weld spatter or other damaging contaminants.
Always report any malfunction, unusual performance or damage of lifting equipment to the appropriate person promptly.
Always inspect the chain block regularly, replace damaged or worn parts and keep appropriate records of maintenance.
Always use genuine Tiger parts when repairing the chain block.
Always apply lubricant to the load chain as recommended in this manual.
Always make sure that you and others are clear of the load before lifting begins and stay clear of the suspended load.
Always warn personnel of your intention to move a load in their area. The operator may start moving the load only after it has
been attached correctly and all persons are clear of the danger zone.
Always make sure that the chain length is long enough for the intended job.
Always check that the hook latches are in proper working order before use (Refer to Chapter 6). Replace missing, damaged or
broken hook latches.
Always be sure that the hoist's rated capacity, which is found on the hoist's name plate/label and forged into the hooks, is in
excess of the weight of the load.
Always keep the load from hitting the chain.

2. General Information
The information in this manual is directed to the proper use, care and maintenance of the product and does not comprise a
handbook on the broad subject of rigging. Rigging can be defined as the process of lifting and moving heavy loads using
hoists and other mechanical equipment. Skill acquired through specialised experience and study is essential to safe rigging
operations. Remember, proper rigging and lifting techniques are the responsibility of the operator.
Each Tiger chain block is built in accordance with the specifications contained herein and at the time of manufacture
complies with our interpretation of applicable sections of the European standard BS EN 13157:2004+A1:2009, the Australian
standard AS1418.2, the American standard ANSI/ASME B30.16, and the South African standard SANS 1594. Chain blocks
supplied with slipping clutch overload protection are compliant with the Norwegian Standard NORSOK R-002. All items come
with a test certificate or an EC Declaration of Conformity stating compliance with the essential health and safety requirements
of the Machinery Directive 2006/42/EC. Tiger chain blocks are third party verified by SGS Certificate Number MDC 1302.
Unpacking
After opening the carton, the product should be carefully inspected for damage which may have occurred during shipment or
handling. Check the chain block frame for dents or cracks and inspect the load chain for nicks and gouges. If shipping damage
has occurred, contact your supplier.
Choose the Right Chain Block for the Job
The load capacity indicated on the unit is the maximum working load limit (WLL) that may be attached. Choose a chain block
with the capacity for the job. Know the capacities of your loads, then match them. The application, environment it is to be used
in, the size and type of load, the attachments to be used and the period of use must also be taken into consideration in
selecting the right chain block for the job. Remember the chain block was designed to ease our burden, and carelessness not
only endangers the operator, but in many cases, a valuable load.
Hoists are designed to provide a 4 to 1 safety factor. Supporting structures and load-attaching devices used in conjunction
with this hoist must provide an adequate safety factor to handle the rated load, plus the weight of the hoist and attached
equipment. This is the customer’s responsibility. If in doubt, consult a registered structural engineer.
! WARNING
Operating a unit with obvious external damage may cause the load to drop and that may result in personal injury and/or
property damage. To avoid injury carefully check unit for external damage prior to installation.

Inspecting
In addition to regular periodic maintenance inspections all chain blocks should be visually examined before being used.
(Refer also to Chapter 5 –Inspection). The purpose of pre-use checks is to identify faulty equipment. Hoists are supplied fully
lubricated from the factory. Lubrication of the load chain is recommended before initial hoist operation. See the section on
Cross-Hauling (Chapter 4) for any usage of Tiger chain blocks that does not involve working in a direct line of pull.
After use
Service the hoist before storing it. See Chapter 8 for more information on storage.
Clean the hoist thoroughly.
Keep the hoist well-lubricated. Oil the load chain and hook shank.
Store the hoist correctly against rain and moisture.
When the hoist is installed outdoors, exceptional care should be taken regarding
maintenance. See Chapter 7 Maintenance for more information.

3. Function/Operation
Hand operated manual chain blocks are actuated by pulling on the hand chain that is fitted to a pocketed wheel that when
rotated acts on the brake and either raises or lowers a load.
The hoist may be used at ambient temperatures between -40°C (-40°F) and +50 °C (+122 °F). Consult the manufacturer in the
case of extreme working conditions.
Note: Before use at ambient temperatures of less than 0°C, check the brake for freezing by lifting and lowering a small load 2 -
3 times. Before operating the hoist in special atmospheres (high humidity, salty, caustic, alkaline) or handling hazardous
goods (e.g. molten compounds, radioactive materials), consult the manufacturer for advice.
Loads can be moved horizontally with the use of a trolley. Always transport the load in the horizontal direction slowly, carefully
and close to the ground. Alternatively, refer to the section on cross hauling (Chapter 4)
Operation
Face the hand chain wheel side of the hoist.
Lifting the load
Pulling the hand chain in clockwise direction will raise the load.
Note: Depending on the type of load picked up, the lifting height may be reduced for units fitted with a chain container.
Lowering the load
Pulling the hand chain in anticlockwise direction will lower the load.
Note: The clicking sound of the pawl when a load is being raised indicates normal operation.
On TCB hoists with two chain block heads, use two operators, one on each of the two hand chains. To keep the load chain
centred in the block assemblies, operate the units simultaneously and at the same speed. An equal amount of unloaded chain
must be maintained under each hoist body.
Stop operating in the lifting direction when the hook block contacts the hoist body, as noted by the sudden increase in the
hand chain pull or the tipping of the hook block.
The operator must ensure that the hoist is suspended in a manner that makes it possible to operate the unit without
exposing himself or other personnel to danger by the unit itself, the suspension or the load.
Stand clear of all loads and avoid moving load over the heads of other personnel. Warn personnel of your intention to
move a load in their area. When the unit is not in use, position the suspension (e.g. bottom block, load hook) above normal
head height, if possible.
Do not allow load chain on hoists with two chain block heads to accumulate on one side (under one hoist body). Excessive
loading to load chain anchor may occur resulting in a falling load which can cause death, injury or property damage.
! WARNING
If parts of the hoist are dropped, they can cause injury, death or property damage. Adequately support the hoist during
installation.

Manual Tiger TCB-SS12 En 201605 v3.1
Operating Principle of Overload Protected Chain Block
If the chain block is fitted with a slipping clutch overload mechanism then it is protected from overload.
The overload protection device is normally set to engage when a load of approximately 135% (±10%) of the WLL is lifted,
unless otherwise specified during purchasing. When the load limit is exceeded, the clutch in the chain wheel will slip, allowing
the hand wheel to be rotated whilst not engaging the gear box. This prevents further lifting of the load, though lowering is still
possible. Continual overloading of the unit must be avoided as the efficiency of the clutch may be impaired. The overload
clutch is factory set and should only be adjusted or repaired by a Tiger authorised repairer. If there is any doubt as to the
unit’s ability to lift a load then don’t. Remove the unit from service and have it checked by your local Tiger distributor or
service centre.
4. Cross Hauling/Fleeting Operations
The TCB and SS12 ranges of chain blocks fitted with the patented protected twin pawl quad cam brake system have undergone
a full and comprehensive testing regime that was drawn up by industry specialists and Tiger’s mechanical engineers to
provide evidence that these units can be safely used for “fleeting” and “cross-hauling” applications up to 45°.
Note: All such operations should be carried out in accordance with manufacturer’s instructions and fully risk assessed by a
competent person.
Never disassemble or attempt to adjust the overload limiter assembly. Any attempt to do so will void the warranty.

Manual Tiger TCB-SS12 En 201605 v3.1
As well as following any industry or country specific guidance on chain blocks used at an angle to the vertical, we recommend
that before commencing an operation using multiple hoists or involving the transfer of a load from one hoist to another, the
following is adhered too:
All the units that are to be used in such an operation must be of the same make and model and have the same rated
capacity.
Attachment points are critical and the suspension point must have a rated capacity equal to or greater than that of
the load to be lifted at the angle that the load will be a carried through.
The attachment points must be designed and certified to work at angles away from the vertical.
The attachment points must be the correct size to allow the hooks to attach correctly in the bowl of the hook and
have enough clearance to allow the hook room to articulate.
All fleeting operations should be risk assessed by a competent person.
Load calculations and method statements should be produced.
Proximity hazards should be accounted for.
The load chain should be kept free of any twists and must enter the hoist body in a straight line over the load sheave.
Care should be taken on multi fall hoists to ensure the bottom hook is not is capsized/rolled over (i.e. bottom hook
has looped through the multi fall chain) which results in the chain becoming twisted.
When taking up the load or beginning the transfer between hoists particular care should be taken to align the block
body so the hand chain is hanging vertically from the block and that the hoist body, load chain and top and bottom
hooks are all in line.
The top and bottom hooks should be free to rotate within the hook yoke and cannot become trapped or jammed
causing stress areas in both the hook and the body.
5. Inspection
According to national and international accident prevention and safety regulations (for example LOLER for the UK), hoisting
equipment must be inspected:
in accordance with the risk assessment of the operating company
prior to initial operation
before the unit is put into service for any subsequent use
after substantial changes
however, at least once per year, by a competent person.
Note: Actual operating conditions (e.g. operation in galvanizing facilities) can dictate shorter inspection intervals.
The intervals of inspection must be determined by the individual application and are based upon the type of service to which
the chain block will be subjected.
Prior to initial operation, before it is put into operation again and after substantial changes
Before the unit is put into operation, for the first time, for a subsequent use or after substantial repair or modification, unless
you have received physical evidence that a thorough examination has been carried out which shows that the chain block is
safe to use, it should be thoroughly examined by a competent person in compliance with applicable statutory regulations.
Typical pre-use inspection will consist of a visual inspection and a function check. These inspections are intended to establish
that the hoist is in a safe condition, has been set up appropriately and is ready for operation, and that any defects or damage
are detected and eliminated.
Inspect the chain block for operation warning notices and legibility. Deficiencies should be noted and brought to the attention
of supervisors. Be sure defective chain blocks are tagged and taken out of service until repairs are made. Under no
circumstances should you operate a malfunctioning chain block.

Figure 1
The following checks should be carried out before starting work:
Check the unit
Inspect the unit for visual defects, e.g. deformations, damage, cracks, wear and corrosion marks.
Check that the name plate/label showing the hoist capacity is attached and clearly legible.
Check lubrication and lubricate if necessary.
Check the functioning of the chain drive in unloaded condition. When facing the hand chain side of the hoist with no
load, the brake is operating normally if the pawl "clicks" when the hand chain is wound in a clockwise direction and
does not "click" when operated in the anti-clockwise direction.
Check for loose or missing nuts and for missing split pins.
Check the brake function
Before starting work, always check operation of the brake. To do this, lift, pull or tension, then lower or release a load over a
short distance with the unit. When the hand chain is released, the load must be held in any position. This check is intended to
ensure that even at temperatures below 0 °C, the brake discs are not frozen. Repeat this at least twice before starting further
work. Stop the load at various positions to test holding power and observe the amount of drift, if any.
To adjust the brake: (See Figure 1)
A. Fully-tightened the check nut (C-31).
B. Slacken off slightly from Position A, and insert the cotter/split pin (C-32) in the check
nut.
Note: Replace the brake disc if thickness is less than 1.5mm (0.06 inch). If the brake
discs are bonded with the ratchet gear, the entire bonded unit will need to be replaced.
Inspect the supporting structure and attachment point
Inspect the supporting structure for visual defects, e.g. deformations, damage, cracks, wear and corrosion marks.
The attachment point for the hoist must be selected so that the supporting structure to which it is to be fitted has sufficient
stability and to ensure that the expected forces can be safely absorbed. The unit must align freely also under load in order to
avoid impermissible additional loading. Check that the hoist and the load are correctly attached. The selection and calculation
of the appropriate supporting structure are the responsibility of the operating company.
Inspect the hand chain
If the unit’s hand chain has been supplied with a Tiger Hand Chain Joiner link, make sure that it has been fitted correctly and
is in good working order. See Chapter 6 Chain and Hooks for more information.
Inspect the load chain
Inspect the load chain for sufficient lubrication, mechanical damage and check for external defects, deformations, superficial
cracks, wear, excessive rust and corrosion marks. Check for gouged, twisted and distorted links, and for deposits of foreign
material which may be carried into the chain block mechanism. Do not operate chain blocks with twisted, kinked or damaged
chain links. See Chapter 6 Chain and Hooks.
If the brake does not function properly, the unit must be immediately removed from service and placed in a quarantine
area until it can be repaired by a relevant competent person.

Manual Tiger TCB-SS12 En 201605 v3.1
Inspection of the Load Chain Anchoring
The load chain anchoring must always be fitted securely at both ends. There must be no wear or incorrect alignment.
Inspection of the top hook and bottom load hook
The top and load hooks must be checked for cracks, deformations, damage, wear and corrosion marks. The safety latch must
be attached, move freely and be fully functioning. Hooks that are bent, worn or have openings which are enlarged beyond
normal throat opening (Chapter 12 Technical Data/Hooks) should not be used. If the latch does not engage in the throat
opening of the hook, the chain block should be taken out of service. Hooks that do not fulfil all requirements must be replaced
immediately. See Chapter 6 Chain and Hooks and Chapter 12 Technical Data/Hooks for more information. Welding on hooks,
e.g. to compensate for wear or damage is not permissible.
Inspection of chain reeving in the bottom block
All units with two or more chain falls must be inspected before initial operation to ensure that the load chain is not twisted or
kinked. The chains of hoists with two or more falls may become twisted if the bottom block is rolled over “capsized” (i.e.
bottom hook has looped through the multi fall chain). A twist in the load chain can damage the chain block and cause injury.
And finally, listen (while hoist operates) for unusual sounds which may indicate trouble.
Thorough Examination
Thorough Examination may be needed at several points during the life of the unit: on initial use or following installation,
periodically during its life, or following exceptional circumstances. This chain block must be subject to periodic thorough
examination in compliance with national statutory regulations. The intervals between periodic thorough examinations must
consider the following:
The condition of the unit.
The environment in which it is to be used.
The number of lifting operations and loads lifted.
Reports of thorough examination can be based on statutory maximum intervals or via a written examination scheme based on
risks and hazards associated with use. i.e.:
Annual Inspection.
Period defined by examination scheme.
Following exceptional circumstance.
Due to the construction of the chain block, it will be necessary to partially disassemble the unit to perform the periodic
inspections.
Figures in the table in brackets refer to spare parts –see Chapter 13 for exploded diagrams of the various capacity chain
blocks.

Initial inspection and recurring inspections must be documented. Chapter 14 contains the inspection log which must be
maintained for each block. Any deficiencies noted are to be corrected before the chain block is returned to service.
The external conditions may show the need for a detailed inspection which, in turn, may require the use of non- destructive
type testing. Any parts that are deemed unserviceable are to be replaced with new parts before the unit is returned to service.
It is very important that the unserviceable parts are destroyed to prevent possible future use as a repair item and are properly
disposed of.
Note: Only qualified personnel to perform chain block maintenance.

6. Chain and Hooks
The hooks and load chains are made of special alloy-steels and are precisely heat-treated. Never weld or heat-treat them
again.
Load Chain
The load chains are exceptionally long-wearing, but wear is unavoidable and certain conditions will cause wear and corrosion
that will lessen the strength. Inspect the load chain for sufficient lubrication, mechanical damage and check for external
defects, deformations, superficial cracks, wear and corrosion marks.
Round steel section chains must be replaced when the original nominal thickness ´d´ on the chain link with the worst wear
has been reduced by more than 10% or when the chain has elongated to a value greater than the discard levels shown in the
tables below. There are two alternative tables for either measuring the chain over 21 links or measuring the chain over 7
pitches. Chain should be clean, free of twists and pulled taut before measuring.

Manual Tiger TCB-SS12 En 201605 v3.1
Do not knot the load chain or splice/connect it by using pins, bolts, screw drivers or similar. Do not repair load chains installed
in the hoist. Protect load chain from weld spatter or other damaging contaminants.
Only fit load chains which have been approved by the manufacturer. Non-compliance with this specification will render the
legal warranty or guarantee void with immediate effect. See the Chapter 7 Maintenance for more information on maintenance
of the load chain.
Hand chain
Tiger hand chain is 5mm × 24mm and either galvanised hand chain (generally for TCB blocks) or corrosion protected hand
chain (generally for SS12 blocks).
Only fit hand chains which have been approved by the manufacturer. Non-compliance with this specification will render the
legal warranty or guarantee void with immediate effect. See Chapter 7 Maintenance for more information on maintenance of
the hand chain.
If the unit’s hand chain has been supplied or subsequently fitted with a Tiger hand chain joiner link (HC-050-JL) make sure
that it has been fitted correctly and is in good working order.
Make sure that the HC-050-JL has been fitted in the correct orientation as shown in figure 1 below. To achieve this, the
HC-050-JL stainless steel rivet heads must be facing the front of the chain block and the joiner link must sit vertically within
the hand wheel pocket as seen in figure 2 below:
Figure 1 Figure 2
Regularly inspect the HC-050-JL. In the event of any defects remove from service and refer the hoist to a competent person for
thorough examination:
Wear: make sure that the two stainless steel rivet heads are complete and have not been worn away or corroded,
ensure the rivets are secure and tight a have solid hold of both plates.
Damage: ensure the link has not been damaged and that both sides of the link join together to form a flat surface
without any signs of distortion by being: bent, twisted, cracked, corroded or stretched.
If the rivets are to be replaced during inspection or maintenance, the dimensions are 2.4mm × 6.0mm and must conform to
EN ISO 15983 and the material is stainless steel. These and the joiner links are available as a spare part from Tiger.
Hooks
Do not remove the safety latches from top and/or bottom load hooks unless you are replacing them with new latches.
Never mark or hard stamp hooks or any other load bearing parts.

The hook opening will elongate with overloads and incorrect hooking. When the hook measurements have changed beyond
the permissible discard limits shown in the table in Chapter 12 Technical Data/Hooks, it is dangerously deformed and must be
replaced immediately.
Dye penetrant, magnetic particle inspections (MPI) or other suitable crack detecting inspections should be performed on
hooks at least once a year, if external conditions indicate there has been unusual usage.
Newer models of the TCB are fitted with the patent pending Tiger “EZ check”3 point marking system. With this system a quick
check that the A and B measurements are the same (as shown in the diagram below) will indicate if the hooks have stretched
If AB the hook is fine; If A>B the hook needs to be replaced:
7. Maintenance
Never perform maintenance on the hoist while it is supporting a load.
Before performing maintenance attach a notice/tag to the block to indicate that it must not be used while maintenance is
in progress.
Servicing and repairs should only be carried out by qualified, competent, and responsible people.
After performing any maintenance to the hoist, always perform a functional test before returning to service. After the
replacement of components, a subsequent inspection by a competent person is obligatory!
Repair work may only be carried out by a specialist workshop that uses original Tiger spare parts.
Before handling lubricants, read the associated product health and safety data information sheet obtained from the
lubricant supplier.

Load Chain
To determine if load chain should be continued in service, check gauge lengths and condition. Chain worn beyond the
maximum allowable gauge length (as shown in Chapter 6), nicked, gouged or twisted chain should be replaced before
returning the chain block to service.
In most cases, chain wear in the link points is caused by insufficient care of the chain. In order to ensure optimal lubrication
of the link contact points, lubricate the chain at regular intervals with appropriate lubricant, taking into account the
application, temperature range, corrosion resistant properties required and other relevant conditions.
It is recommended that you lubricate load chain at least weekly, or more frequently than normal depending on severity of
service. Apply new lubricant over existing layer. Lubricate chain more frequently in a corrosive environment. Corrosion
resistant chain is available for Tiger chain blocks as an option on TCB models.
A dry film lubricant, e.g. PTFE spray, should be used in environments where abrasives like sand, etc., occur. The service life of
the load chain can be increased by careful lubrication to 20 - 30 times, compared with a chain that is not serviced.
When lubricating the chain, make sure the chain is in no-load condition so that the oil can reach the contact points
(crown/saddle) of the chain links which are subject to wear. Chain link parts contacting each other must always be coated with
lubricant otherwise increased wear on the chain results.
It is not sufficient to lubricate the chains on the outside as this does not ensure that a lubricant film can build up in the
contact points.
Make sure that the load chain is lubricated over its entire length, also including the part of the chain in the housing of the
hoist around the load sheave/wheel. Remove excess lubricant from the chain by wiping with a cloth.
When lubricating the chain, also check the chain for wear.
Clean dirty chains with acid free or water based solvent or a similar cleaning agent, to remove rust or abrasive dust build up.
Never heat the chain.
Replacing the load chain
The load chain must be replaced by a new chain of the same dimensions and quality in the event of visible damage or
deformations, or when the discarding status has been reached, at the latest.
A load chain to be discarded must only be replaced by an authorised competent person. Only fit load chains which have been
approved by the manufacturer. Non-compliance with this specification will render the legal warranty or guarantee void with
immediate effect.
If the chain links are not deformed, the chain can be replaced with the hoist in the suspended position as in the instructions
below. Alternatively, remove the hoist from the suspension point and work on a bench. If the chain is jammed in the lifting unit
the hoist must be removed and stripped.
Note: Replacement of a load chain must be documented!
Make sure that no lubricant can penetrate into the brake enclosure. This may result in failure of the brake.

Hoist with single fall
1. Only pull in the new chain in no-load condition (if the hoist is not loaded).
2. An open load chain link (split link) is required as a tool. It can be obtained by using an abrasive wheel to cut a section
from an existing link with the same dimension. The length of the cut section must at least correspond to the thickness of
the link.
3. Remove the bottom hook from the old load chain and suspend the open load chain link (split link) in the loose end of the
load chain.
4. Suspend the new lubricated load chain also in the open link and pull it in (chain movement UP).
5. Do not fit a twisted chain. The welds must face outwards from the load sheave/wheel.
6. When the old load chain has passed through the hoist unit it can be detached together with the open chain link and the
bottom hook can be fitted on the new load chain just pulled in.
7. Fix the slack end of the new load chain on the anchor on the housing or frame (depending on model) of the hoist.
Multi-fall hoists
1. Only pull in the new chain when the bottom block is unloaded, otherwise the bottom block may drop when the load chain
is detached. Danger of injury!
2. An open load chain link (split link) is required as a tool. It can be obtained by using an abrasive wheel to cut a section
from an existing link with the same dimension. The length of the cut section must at least correspond to the thickness of
the link.
3. Detach the loaded-fall (tight/operational) end of the load chain from the top or bottom hook assemblies (depending on
capacity).
4. Suspend the prepared, open load chain link in the now free load chain end.
5. Suspend the new, lubricated load chain also in the open link and pull it through the bottom block and the hoist unit
(chain movement UP).
6. Do not fit a twisted chain. The welds must face outwards from the load sheave/ wheel.
7. When the old load chain has passed through the hoist unit it can be detached together with the open chain link.
8. Fix the loaded-fall (tight/operational) end of the new load chain on the housing/frame or on the bottom block (depending
on model) of the hoist.
9. Fix the slack end of the idle fall on the hoist instead of the old load chain.
Before returning chain to service or after replacing a load chain, lubricate liberally with chain oil or equal lubricant. Remove
excess lubricant from the chain by wiping with a cloth.
Note: Worn chain can be an indication of worn chain block components. For this reason, the chain block’s chain guide roller
and load sheave/wheel should be examined for wear and replaced as necessary when replacing worn chain.
Load chains are specially heat treated and hardened and should never be repaired.
The slack end of the idle fall must always be fitted to the chain end anchorage.
Using other than Tiger supplied or approved load chain may cause the chain to jam in the chain block and/or allow the
chain to break and the load to drop. Due to the size requirements and physical properties, use only Tiger approved load
chain in Tiger TCB or SS12 chain blocks.
Do not use replaced chain for other purposes such as lifting or pulling. Load chain may break suddenly without visual
deformation. For this reason, cut replaced chain into short lengths to prevent use after disposal.
Failure to maintain clean and well lubricated load chain will void the manufacturer's warranty.

Hand Chain
Hand Chain should be cleaned, inspected and checked for damage.
Changing the length of the hand chain
The hand chain on a TCB chain block is normally supplied to hang 500mm shorter than the height of lift of the load chain. For
particular applications it may be supplied at a different length or may need to be adjusted to a different length. Or if the height
of lift has changed and the load chain replaced, the hand chain may need to be adjusted.
The hand chain may contain an unwelded link. This link can be placed in a vice and twisted open to facilitate changing chain
or chain length. Please note that opening and closing of the connecting link more than twice is not recommended.
The hand chain may contain a special riveted Tiger hand chain joining link (HC-050-JL). This link can be removed by drilling
the rivets out.
Use a new link to close the loose chain ends by bending it or use a Tiger hand chain joiner link and stainless steel rivets
available from your Tiger supplier. For extending the hand chain, two new chain links or Tiger hand chain joiner links are
required.
Note: See Chapter 6 Chain and Hooks for information about the orientation of the Tiger hand chain joiner link.
Note: Always remove or add an even number of chain links.
Note: Care must be taken to ensure that there is no twist in the hand chain loop.
Replacing the hand chain
Take the hand wheel cover off and replace the hand chain with a new hand chain loop.
