1. GENERAL INFORMATION
Attention: All users must read these operating instructions carefully prior
to the initial operation. These instructions are intended to acquaint the
user with the hoist/trolley and enable him to use it to the full extent of
its intended capabilities.
The operating instructions contain important information on how to
handle the hoist/trolley in a safe, correct and economic way. Acting
in accordance with these instructions helps to avoid dangers, reduce
repair costs and downtime and to increase the reliability and lifetime
of the hoist/trolley.
Anyone involved in doing any of the following work with the hoist/trolley
must read the operating instructions and act accordingly:
•Operation, including preparation, trouble shooting and cleaning
•Maintenance, inspection, repair
•Transport
Apart from the operating instructions and the accident prevention act
valid for the respective country and area where the hoist / trolley is used,
also the commonly accepted regulations for safe and professional work
must be adhered to.
The user is responsible for the proper and professional instruction of
the operating personnel.
Every unit leaving the factory is furnished with a test certificate that
shows the serial number of the hoist / trolley. This certificate has to be
filed together with the inspection manual.
The continuous sound level at the place of work is equal to >70 dB.
The measurements were taken at a distance of 1 m from the hoist at 9
positions in accordance with DIN 45635, precision class 2.
2. CORRECT OPERATION
Maximum capacity
The Yale electric chain hoist series CPE/F has been designed to lift
and lower loads up to the rated capacity. The lifting capacity indicated
on the hoist/trolley is the maximum safe working load which must not
be exceeded.
Danger zones
• Do not allow personnel to pass under a
suspended load (see Fig. 2).
• After lifting or tensioning, a load must
not be left unattended for a longer
period of time.
• Start moving the load only after it has
been attached correctly and all personnel
are clear of the danger zone.
Attaching the hoist / trolley
• The operator must ensure that the hoist / trolley is attached in a
manner that does not expose himself or other personnel to danger by
the hoist, trolley, chain(s) or the load.

Temperature range
The units can be operated in ambient temperatures between -20°C and
+50°C. Consult the manufacturer in case of extreme working conditions.
Theoretical service life
The electric chain hoist is classified to group 1 Am according to FEM
9.511. Basic principles for the calculation of the theoretical remaining
service life are given in BGV D8. When the theoretical remaining service
life has been reached, the electric chain hoist should be subjected to a
general overhaul (also refer to para 8 Maintenance).
Regulations
The accident prevention act and/or safety regulations of the respective
country for using manual and electric hoists must be strictly adhered to.
In Germany these are BGV D6, BGV D8, BGR 500 and VDE 0113-32 /
EN 60204-32:1999.
Maintenance / Repair
In order to ensure correct operation, not only the operating instructions,
but also the conditions for inspection and maintenance must be complied
with. If defects are found or abnormal noise is to be heard stop using
the hoist / trolley immediately.
Attention: Before starting work on electrical components the power
supply is to be cut off.
3. INCORRECT OPERATION
•Do not exceed the rated capacity of the hoist / trolley.
•Do not lift stuck or jammed loads.
•Excessive inching operation by short and frequent actuation of the
control switch should be avoided.
•Do not use the hoist /trolley for the transportation of people (Fig. 3).
•Welding on hook and load chain is strictly forbidden. The load chain
must never be used as a ground connection during welding (Fig. 4).
•Avoid side pull, i.e. side load on either housing or bottom block (Fig. 5).
Lift only when the load chain froms a straight line between both hooks.
•The load chain must not be used for lashing purposes (sling chain)
(Fig. 6).
•Do not knot or shorten the load chain by using bolts, screws, screw-
drivers or other devices (Fig. 7). Load chains that are integral part of
the hoist/trolley are not allowed to be repaired.
•Do not remove the safety latch from suspesion hook or load hook
(Fig. 8).
•Do not use the chain end stop as an operational limit device (see Fig.
1 - chain end stop).
•Do not throw the hoist or trolley down. Always place it properly on
the ground.
•The unit must not be operated in potentially explosive atmospheres.
•The longitudinal downward slope of the carriageway must not exceed
0,3 %.
•The adjustment of the trolley width must not be extended in order to
e.g. obtain a smaller radius curvature.
•Any modifications of the hoist or trolley are prohibited.
•Load can not fall into the loose chain - risk of chain break!
•Never attach the load to the tip of the hook. The load must always be
seated in the saddle of the hook. This also applies to the suspension
hook.
•Turning of loads under normal operating conditions is not allowed, as
the bottom blocks of the hoists are not designed for this purpose. If
turning of loads is required as standard, the bottom blocks have to
be provided with swivel hooks supported by axial bearings. In case of
queries consult the manufacturer. Beim Drehen einer angehobenen
Last darf sich die Lastkette unter keinen Umständen mitdrehen.
•Never attach more than one load lifting attachment to the load hook
of the hoist or trolley.

3. On chain hoists without electric trolley the mains supply and the
ground/earth wire are to be connected to the terminal strip within
the terminal box of the chain hoist.
4. After removing the terminal box cover, connect the wiring as shown
on the wiring diagram label inside the terminal box cover.
Attention: On hoists with direct control the ground/earth wire should
always be connected according to the wiring diagram. Should the
mains supply source not provide a ground (earth) connection please
consult the manufacturer.
5. After replacing the terminal box cover, connect the other end of the
supply cable to the mains supply.
6. Check the motor's direction of rotation.
The wiring diagram included has been drawn for a normal, clockwise
rotating installation.Should the user's mains supply not fulfil these
requirements, e.g. the hoist lowers when ''lift'' is selected (or vice
versa) switch the unit OFF immediately and exchange two of the
three phase connections in the mains connection.
Attention: Under no circumstances may the wiring in the pendant
control be tampered with.

7. OPERATION
Installation, service, operation
Operators delegated to install, service or independently operate the
hoist must have had suitable training and be competent. Operators are
to be specifically nominated by the company and must be familiar with
all relevant safety regulations of the country of use.
5. FUNCTIONAL CHECK AFTER ASSEMBLY
Prior to operating the hoist, grease the trolley pinions (manual geared
and electric trolleys) and lubricate the load chain when it is not under
load (see page 9).
Before the hoist is put into regular service, following additional inspec-
tions must be made:
•Are all screwed connections on hoist and trolley tight and are all locking
devices in place and secure?
•Are the end stops on the trolley runway in place and secure?
•Is the chain drive correctly reeved?
•Is the chain end stop correctly fitted to the loose end of the load chain?
•All units equipped with two or more chain strands should be inspected
before initial operation for twisted or kinked chains. The chains of
2-strand hoists may be twisted if the bottom block is rolled over.
•Perform an operation cycle without load. The chain should move in a
steady, smooth way. Check the function of the overload device by raising
the bottom block against the hoist body (max. 5 sec.).
•Check the brake function when lifting and lowering. The braking
distance must not be more than 50mm.
• Traverse the trolley (if available) the complete length of the trolley runway
ensuring that the 2 - 4 mm lateral clearance between the trolley wheel
flange and the beam outer edge is maintained at all times. Check that
beam end stops are positioned correctly and secure.
6. COMMISSIONING
Inspection before initial operation
Each hoist/trolley must be inspected prior to initial operation by a com-
petent person and any failures be removed. The inspection is visual and
functional. These inspections have to assure that the hoist is safe and
has not been damaged by incorrect transport or storage. Inspections
should be made by a representative of the manufacturer or the supplier
although the company can assign its own suitably trained personnel.
Inspections are instigated by the user.
Inspection by a crane expert
If the hoist is used as a crane, it has to be inspected and approved by a
crane expert before initial operation. This inspection has to be registered
in the crane inspection book. The inspection by the crane expert has to
be instigated by the operating company.
Inspection before starting work
Before starting work inspect the hoist/trolley, chains and all load bearing
components every time for visual defects. Furthermore test the brake
and make sure that the load and hoist/trolley are correctly attached by
carrying out a short work cycle of lifting and lowering resp. travelling in
both directions. Selection and calculation of the proper suspension point
and beam construction are the responsibility of the operating company.
Inspection of load chain
Inspect the chain for sufficient lubrication and visually check for external
defects, deformations, superficial cracks, wear or signs of corrosion.
Inspection of chain end stop
The chain end stop must be connected to the free (idle) chain strand
(see Fig. 1 - chain end stop).
Inspection of chain reeving
All units with two or more chain strands should be inspected prior to initial
operation for twisted or kinked chains. The chains of 2-strand hoists may
be twisted if the bottom block was rolled over (Fig. 13).
The load chain has to be installed according to illustration (Fig. 9). Hereby
the welds on the standing links must face away from the load sheave.
Inspecting the hooks
Check the load hook and the suspension hook for deformations, cracks,
damages, abrasion and signs of corrosion.
Attaching the load
The load must always be seated in the saddle of the hook. Never attach
the load to the tip of the load hook (Fig. 14). This also applies to the
suspension hook.
Inspect the traverse (for trolleys)
Inspect the traverse for correct assembly and visually check for external
defects, deformations, superficial cracks, wear or signs of corrosion.
Especially make sure that the roll pins are properly fitted to the centre
traverse (Fig. 10).
Check adjustment of trolley width
On chain hoists with trolley (CPV/F-VTP/G(E) check that the clearance
between the trolley wheel flange and the beam outer edge is equal on
both sides and within the tolerances given (see page 5, Fig. 10).
Enlarging the clearances, e.g. to enable the trolley to negotiate tighter
curves, is forbidden.
Traversing the hoist
Plain trolley:
Push the hoist or attached load.
Attention: Never pull on the pendant control cable. Suspended loads
may only be pushed.
Geared trolley:
By operating the trolley hand chain.
Fig. 13 Fig. 14

Electric Chain Hoist CPE/F

Electric trolley:
By operating theresp.-button.
For trolleys with two speeds: The first stage of button depression activates
the slow speed., further depression activates the fast speed. Use the
slow speed for short periods only.
When moving the trolley consider the stopping distance. Do not use the
beam end stops as operational limit devices.
Attaching the load
Attach the load to the hoist using only approved and certified slings or
lashing devices. Never use the load chain as sling chain. The load must
always be seated in the saddle of the hook. Never attach the load to
the tip of the hook. Do not remove the safety latch from the load hook.
Lifting/lowering the load
The load is lifted by depressing the-button, it is lowered by depres-
sing the- button. For hoists with two speeds: The first stage of button
depression activates the slow speed, further depression activates the
faster speed. In order to raise the load, always use the lowest available
lifting speed. The chain must be loaded at this speed and may not lie
slack on the floor. The slow speed may only be used for short distances.
The chain end stop may not be used as operational limit switch (see Fig.
1). Use the slow speed for short periods only. Do not use the chain end
stop as operational limit device.
Emergency stop
All movement can be immediately halted by depressing the red,
mushroom shaped button on the pendant control.
Attention:
Operating the red emergency button does NOT automatically disconnect
the mains supply to hoist or trolley.
To release the emergency stop, rotate the button in an clockwise direction.
8. SERVICE
• Service and inspections may only be carried out by a competent person.
•The inspection must determine that all safety devices are present
and fully operational and covers the condition of the hoist, lifting gear,
accessories and supporting constructions.
•The service intervals and inspections noted are for normal working
conditions. Adverse working conditions, e.g. heat or chemical envi-
ronments, can dictate shorter periods.
•The Yale electric chain hoist CPV/F conform to FEM group 1Am in
accordance with FEM 9.511. This results in a theoretical service lifetime
of 800 operating hours under full load.
•This is equivalent to 10 years under normal operating conditions. After
this period the hoist requires a general overhaul. Further information
is contained in BGV D6 resp. FEM 9.755.
Attention: Maintenance work requires subsequent function testing with
nominal load.
8.1 DAILY CHECKS
1. Visually check the pendant control switch and cable for damage.
2. Function test of brake
3. Function test of end limit switch
4. Electric chain hoists with trolley:
• Check that the trolley runway is free from obstructions
• Check that the end stops on the trolley runway are fitted and secure.

8.3 LOAD CHAIN
The load chains are case-hardened and carry the designations
11 x 31 DAT.
The CPE/F electric hoists are specially designed to use this type of chain.
For this reason only chains that have been approved by the manufacturer
may be used in these hoists.
Lubricating the load chain
The load chain is to be lubricated before initial operation and every month,
however, latest after 50 operating hours. Adverse working conditions,
e. g. excessive dust or continued heavy duty can dictate shorter periods
between lubrication.
•Before the chain is lubricated it must be cleaned. Flame cleaning
is forbidden. Use only cleansing methods and agents that do not
corrode the chain material. Avoid cleansing methods that can lead to
hydrogen brittleness, eg. spraying or dipping chain in caustic solvents.
Also avoid surface treatments that can hide cracks and flaws or other
surface damage.
•The chain must be lubricated in a no-load condition so that lubricant
can enter between the links, e. g. by dipping in oil. The chain i s to be
lubricated throughout itsentire length.
•Motor oil of the voscosity 100, e. g. Shell Tonna T68 can be used to
lubricate the chain. For very dusty applications use a dry lubricant.
Inspecting the load chain for wear
Load chains must be inspected every 3 months or the latest after 200
operating hours.
Visually inspect the chain over its full length for deformation, cracks,
flaws, elongation, wear or corrosive pitting.
Link chains must be replaced when the nominal thickness d on any part
of the chain has been reduced by more than 10% or when the pitch t is
elongated by more than 5% or over 11 pitches (11 x t) by 2 %. Nominal
dimensions and wear limits are shown in the following table 2.

1. Remove the chain anchor bolt
The chain anchor bolt is situated on the underside of the hoist body. With
an allen key remove the grub screw that serves as locking device. Tap
out the chain anchor bolt with a drift from the other side.
Attention: Do not damage anchor bolt or bore.
2. Pull the load chain through the bottom block and remove the chain
end stop.
3. Fitting the new chain
Cut the second to last link open on the loose end of the load chain to
form a "C". Remove the last link and connect the new chain. The new

1-strand design
1. Disassemble bottom block
Remove the circlip with suitable pliers. Raise the swivel tube in the
direction of the chain and tap out the chain bolt with a drift.
Attention: Do not damage the chain bolt bore.
2. Remove the chain end stop.
Remove the 2 screws. The chain is now free.
3. Fitting the new chain
Cut the second to last link open on the loose end of the load chain to
form a "C". Remove the last link and connect the new chain. The new
chain must be fitted so that the welds on the standing links face towards
the chain guide and away from the load sheave. Operate the hoist in
the lowering direction (-button) to feed the chain through the hoist.
4. Fitting lower block and chain end stop
Slide the end buffers over the loose ends of the load chain and refit
bottom block and chain end stop. The chain end stop must be fitted so
that at least 1 link remains free (see Fig. 1).
Attention: Use new hexagon locknuts.
5. Before initial operation lubricate the unloaded chain and test all hoist
functions under no-load condition.

8.2 REGULAR INSPECTIONS, SERVICE AND TESTING
According to prevailing national/international occupational safety and
health regulations, hoisting equipment must be inspected at least an-
nually by a competent person. Adverse working conditions may dictate
shorter inspection periods.
The commissioning and inspection details can be noted on the test
certificate delivered with the hoist or on page 14 of this manual. Repairs
may only be carried out by specialist workshops that use original Yale
spare parts. The inspection must determine that all safety devices are
present and fully operational and cover the condition of the hoist, lifting
gear, accessories and supporting constructions.
If required by the Occupational Health and Safety Organisation, the re-
sults of the adequate inspections and competent performance of repairs
have to be substantiated. If the electric hoist (with capacity of 1t and
up) is installed in a carriage, or if the load is moved in one or several
directions, the installation is considered as crane and inspections have
to be carried out in accordance with BGV D6-Cranes.
Attention! Power supply must be disconnected while inspecting the
device, unless the type of the examination excludes this.
Chains that do not fulfil all requirements must be replaced immediately.
