2.2Mechanical Classification (Grade) and Life
Safety and life of electric chain hoists are guaranteed only when the equipment is operated
in accordance with the prescribed grade.
Pacific electric chain hoists have been designed for grade 2m in the FEM Regulations
(FEM 9.5.11). Details are provided in Table 2-2. Average daily operating time and total
operating time are determined by load distribution.

2.3 Safety Devices
(1) Motor brake
The “Electro-Magnetic Brake”unique design, it features simultaneous motor braking upon
switching off power even under full load condition, quick action and high frequency use.
(2) Mechanical Brake w/Clutch & Overload protection device
The unique design includes mechanical brake & overload dual protection. Mechanical clutch
operates with motor brake, which can offer exactly, very limited slipping & quick braking. OL
device prevents over loading to damage goods, and ensure secure operation and product’s
life-span.
(3) Hook and hook latch
The hook is drop-forged from high tensile steel and heat treated for strength and toughness.
The bottom hook is capable of 360∘rotatable and fitted with a safety latch for added security.
(4) Phase Error Relay
To test 3 phases if any wrong phases connection. It can stop power once any abnormal
situation to protect the hoist.
(5) Limit Switch
Upper and lower limit switches are fitted for switching off power automatically in case of over
lifting or over lowering.
(6) Emergency Stop Device
This button is used to quick stop the hoist in an emergency situation. It is a red, mushroom

7
shaped swivel button, located at the uppermost position of the pendant. When pressed, power
to the equipment is switched off and the button locked automatically. Turn it clockwise can
release the lock and enable re-start. (Illust.1)

3.SAFETY RULES
This hoist 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.
Only trained personnel are allowed to operate the hoist.
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.
Do not use the hoist in explosive atmosphere.

9
(Illust. 2)
Firm and steady button operation is required. Never push the button switch intermittently.
Always avoid excessive inching operation.
Always make sure the hoist motor completely stops before reversing.
Always leave the push button switch cable and bottom hook vertically static after completion of
operation, never leave them at any position which may cause swing or slip.
Slings must be applied to load evenly and centrally to ensure correct balance. Never lift any
object which is insecure or out of balance.
Never use hoist to end or side pull a load. (Illust. 3)
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)

10
(Illust. 5)
Lifting must always be personally attended. Never leave a raised load unattended.
Over-capacity-load lifting is hazardous and should not be undertaken.
Never lift a load when the load chain is twisted.
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, gearbox 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 set
2. Power cable 0.5 meter
3. Push button control switch 1 piece

11
Table. 4-1
4.2 Voltage
4.3 Installation
Prior to installation check and ensure that the top hook assembly is securely attached
to the hoist by means of the lock bolt.
NOTE: If the hoist is to be suspended from an electric trolley, assembly may be eased
by firstly removing the top hook, attaching it to the trolley load plate, them refitting the
top hook to the hoist.
Assemble chain bucket –
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.
Connection to power supply before installation procedures having been completed
is strictly prohibited.

Operation Test
(a) Please reverse any two connections while the direction is incorrect.
(b) Firmly push switch button to lower load chain until the limit spring touches the
limit switch. Power should be cut off automatically.
(c) Firmly push switch button to check the collection of load chain into chain
bucket.

13
(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 any of the
above checks, check the wiring and automatic locking function of the emergency stop
device.
(e) Check load chain lubrication (It has been lubricated at our works, but the lubricant
may dry out during transportation). It is also advisable to keep a small amount of
lubricant in the chain bucket to keep the chain in an oil bath.
(f) Check chain position. Weld joints on links must face the same direction (Illust. 8).
Correct chain operation can only be achieved when all joints are vertically in line.
Illust. 8 Illust. 9
5. OPERATION
The bottom hook on multi-fall hoist must never be rotated as shown below. (Illust.
9)

14
After running test and checks have been completed, the hoist will be ready for normal
operation.
(1) The operator must have a clear and unobstructed view of the entire working area
before operating the hoist.
(2) The operator must check that the entire working area is safe and secure before
operating the hoist.
(3) When using the hoist with a motorized trolley, the operator must take care to
prevent excessive load swinging by sympathetic use of the trolley controls
6. MAINTENANCE AND INSPECTION
6.1 Maintenance
(1) Check the level of gearbox lubricant after the first 500 hours operation, thereafter
check every 3 months and lubricate accordingly.
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.
Do not perform maintenance on the hoist while it is carrying a load except
monthly checking for the brake or limit switch.
Before performing maintenance do not forget to affix tags to the power source
and the push button switch reading : “DANGER”, “EQUIPMENT BEING
REPAIRED”.

15
NOTE: We recommend using lubricant oil equivalent to SHELL S4 WE460.
(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 followings:
(a) Correct power supply.
(b) “Up”, “Down”and “Emergency Stop”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 and brake.
(g) Well-lubricated load chain.
2. Monthly inspection
(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.

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 in part.
(7) The load sheave, regulator, and regulator plate wheel must be replaced the same time as
you do a chain replacement.
Note : Chain must be in perfect condition without any defects.
