2.3 Safety Devices
(1) Mechanical load brake
The mechanical load brake can hold a full capacity load independent of motor brake.
This brake assures that load does not accelerate while being lowered.
(2) Hook and hook latch
The hook is drop-forged from high tensile steel and heat treated for strength and
toughness.
The button hook is capable of 360∘swivel and fitted with safety latch to ensure
Safe lifting.
(3) Limit Switches
Upper and lower limit switches are fitted for switching off power automatically in
Case of over lifting or over lowering.
(4) Emergency stop device
This button is used to stop the hoist in an emergency situation. It is red, mushroom
type button, located in the uppermost position on the pendant. When pressed,
power to the equipment is switch off and button locks automatically. Turning it to
the right will release the lock and to enable re-starting.
(5) Shock protection
It cannot run, when you push the button for anti-direction in "UP" or "DOWN"
running. You must wait over 1 second.

3. SAFETY RULES
The hoist herein is not designed for, and should not be used for, lifting,
supporting, or transporting personnel. Any modifications to upgrade, re-rate,
or otherwise alter the hoist equipment must be authorized by either the original
manufacturer or a qualified professional engineer.
Do not use the hoist in explosive atmosphere.
(1) Prior to each lifting operation, it is essential to make sure that:
(a) the correct lifting sling is being used.
(b) the lifting sling is located in the hook as shown below (Illust. 2) and that a safety latch
has been fitted.
Illust. 2
(c) The object to be hoisted is well secured for direct lifting (a proper lifting frame or
apparatus is strongly recommended for direct lifting .)
(2) Firm and steady button operation is required, never push the button switch
intermittently.
(3) Always avoid excessive inching operation.
(4) Always make sure the hoist motor completely stops before reversing.
(5) Always leave the pendant button switch cable and bottom hook load chain
vertically static after completion of operation, never leave them at any position,
which may allow them swing or slip.

9
(6) Sling must be applied to load evenly and centrally to ensure correct balance.
Never lift any object which is insecure or out of balance.
(7) Never use hoist to end or side pull a load. (Illust. 3)
(8) Never wrap around and hook back the load chain as a sling to lift a load. (Illust. 4)
Illust. 3 Illust. 4
Do not use the hoist chain as a welding electrode.
Never stand under a raised load (Illust. 5)
Illust. 5
(9) Lifting must always be personally attended, never leave a raised load unattended.
(10) Over-capacity-load lifting is hazardous and should not be undertaken.
(11) Never lift a load when the load chain is twisted.
(12) Regularly inspect and check the condition of load chain. Do not operate with
damaged chain.

4. INSTALLATION
4.1 Unpacking Information
After removing the hoist from its packing box, carefully inspect the external condition
of the electrical cables, contactor, gear box and motor casing for damage.
Check and ensure that these items are present.
Each hoist is supplied as standard with the following accessories.
1. Chain bucket 1 piece
2. Power cable 3 meters
3. Separated control cable with PBS and male plug 1 set
Table. 4-1
4.2 Voltage
If power supply deviates from standard by more than ± 10%, abnormal
operation or damage to the motor may result. It is imperative to ensure
correct voltage supply before commencing operation.
4.3 Installation
Connection to power supply before installation procedures having been
completed is strictly prohibited.
The equipment safety earth connection on the plug must NEVER be removed.
(1) Prior to installation check and ensure that the top hook assembly is securely attached
to the hoist by means of the lock bolt (key No.1~6, page.24).
NOTE: If the hoist is to be installed under a trolley, remove the top hook and install the
trolley on the hoist.

11
(2) Assemble chain bucket.
CHAIN BUCKET
HEX. RECESS BOLT LOCK NUT
Illust. 6
(3) Plug power supply to hoist and operate the push button switch. This operation must
be carried out by a trained person.
Illust. 7

12
(4) Operation Test
(a) Firmly push switch button to lower load chain until the chain end buffer touches
the limit switch. Power should be cut off automatically.
(b) Firmly push switch button to check the collection of load chain into chain bucket.
(c) Check load chain lubrication. (It has been lubricated at our works, but the lubricant may
dry out during transportation) Any readily available lubricant is recommended.
It is further advisable to keep a small amount of lubricant in chain bucket to allow chain
in oil bath.
(d) Check the emergency stop device function :
While holding down either or button on the push button switch, push the
emergency stop button. Check that the hook stops when the emergency stop button is
pushed. Also, check the hoist does not move in response to the push button switch.
Finally, check that the emergency stop device pops out when turned to the right and
that operation can be resumed thereafter. If the equipment fails to pass another above
checks, check the wiring and automatic locking function of the emergency stop device.
5. OPERATION
After running test and checks have been completed, the hoist will be ready for normal
operation.
(1) On connection of power supply allow 15 seconds to initiate start up.
(2) The operator must have a clear and unobstructed view of the entire working area
before operating the hoist.
(3) The operator must check that the entire working area is safe and secure before
operating the hoist.
(4) When using the hoist with a plain trolley, the operator must take care to prevent
excessive load swinging by sympathetic push trolley movements.
Since dealing with heavy loads may involve unexpected danger all of the
"SAFETY RULES" (Ref 3.) must be followed and the operator must be aware of the
following points while using the hoist.

13
6. MAINTENANCE AND INSPECTION
6.1 Maintenance
(1) Check the level of gear box lubricant after first 100 hours of operation, thereafter every
3 months and lubricant accordingly. Lubricant use ISO VG460 or equivalent.
(2) Always keep the hoist unit dry and never misuse it in a manner likely to reduce its
durability.
(3) When it is necessary to keep the unit outdoors, a protective covering should be fitted.
6.2 Inspection
(1) Daily inspection: Before starting daily operation, check the following,
(a) Correct power supply.
(b) "Up" , "Down" and "Emergency stop" (where fitted) test runs under no load.
(c) Correct motor performance.
(d) No abnormal or excessive noise.
(e) No malfunction of the bottom hook safety latch.
(f) Proper function of moving/turning parts, limit switches and brake.
(g) Well lubricated load chain.
(2) Monthly inspection
Do not perform maintenance on the hoist while it is carrying a load except monthly
checking for the brake, limit switch or slip clutch.
Before performing maintenance do not forget to affix tags to the power source and
the push button switch reading : "DANGER", "EQUIPMENT BEING REPAIRED".
Always use the hoist manufacture’s recommended parts when repairing a
hoist.

14
(a) Load chain:
Distorted, elongated or worn chain link will not sit properly on the load sprocket wheel
and may cause chain breakage and/or damage to hoist unit. To ensure safe and efficient
operation, the chain links must be checked for their pitch (inside length, inside width) and
outside width monthly according to following table.
Chain Gauge – Wear and Stretch Measuring
(1) The chain gauge is useful and convenience for measuring.
(2) Please use a chain gauge to measure the chain pitch and diameter, such as illustrations
(1) and (2).
(3) Every chain ring must be measured, and the chain must be replaced when one of chain
ring is wear or stretch.
(4) It will be a cutting-out possibility if you use a chain fall either wear or stretch during
operation.
(5) Do not replace a chain fall by yourself and do please contact specific either service
centers or contractors to help you out.
(6) The chain fall must be replaced whole instead of a partial part.
(7) The load sheave, regulator, and chain compressing wheel must be replaced the same
time as you do a second time replacement.
Remark :
(1) Chain must be perfect condition without any defects and attachments.
