Warning 

a)

 

Ensure the hoist has correct earth connection before operation. 

b)

 

Before lifting a load, examine the load chain to ensure that there is no twist, kink, and 
no turn-over of bottom hook for multi-falls. 

c)

 

The hoist is only used for load within capacity, any application for over rated capacity 
is forbidden. 

d)

 

Ensure to lift a load vertically, diagonal lift or tow a load is not allowed beyond 
10degree. 

e)

 

While operating, personnel are prohibited to stand or work underneath the load. 

f)

 

Do not lift any load with the load chain acting as a sling. 

g)

 

Never apply any load to the tip of hook for lifting. 

h)

 

While lifting, do not operate the hoist rapidly up and down & repetitively. 

i)

 

Don’t run the hoist out of the limit position. 

j)

 

Never lift a load using 2 or more than 2 hoists simultaneously. 

k)

 

Don not dismantle and adjust the limit load device.   

l)

 

Measuring the load by load limit device is forbidden. 

m)

 

The load chain should be properly lubricated with suitable oil or grease before applied 
to lifting purpose, and periodic lubrication is necessary in normal operation. 

n)

 

When lifting, the slings should be properly put into the hook throat with the safety latch 
properly closed.

Application 

TECH series electric chain hoist is 

based on Japanese and Germany technology 

with the 

features of compact structure, light weight, easily operation with load limit and thermal 
protection. The hoist is widely used in factories, workshops, mines, ports, warehouses etc, 
and can be used together with cranes as an integral part of an overhead craning system, 
serving as a highly efficient method of operation.

Features 

 

1)

 

Safe and reliable 

a)

 

Brake: adopting D.C. normal close brake, without asbestos. Once the motor 
stops, the brake can hold the load safely and    continually . 

b)

 

This hoist is equipped with an electronic limit load device, which prevents chain 
failure and stretching.   

c)

 

Friction clutch: prevents motor damage due to overloading and chain stretching.   

d)

 

The motor is equipped with a thermal protection device, which preventing the 
motor being damaged due to overheating. 

e)

 

Top and bottom hooks are made of high tensile alloy steel with special heat 
treatment. It prevents the hook from breaking and being deformed gradually 
under a sudden extra-load. 

f)

 

Load chain is carbonized to ensure good wear and long life. 

g)

 

Chain container serves as a storage bag, keeping the load chain clear of dirt and 
dust, and without tangles while falling down freely.
