2.2 Unpacking
After unpacking,pls careful check over the appearance of the cable, gear box and motor
shell.
Check the quantity of the bellowing items as well.
Every set of our hoist should including the bellowing standard spare parts：
1．Chain bag（box）
1pcs
2．Control cable
1mtrs
3．Button switch
1pcs
2.3 Supply voltage
If the supply voltage exceeds ± 10% compare to the standard
voltage, operation may cause damage to the motor under this
abnormal voltage. Thus operator have to confirm whether the
power supply voltage within the operating range of the standard
firstly before operating the hoists.
2.4 Installations
Strictly prohibited connecting to the power before
the completion of the installation process.
（1）Chain bag assembly

ELECTRIC CHAIN HOIST
11
（2）Switch on the power supply to the hoist and operate the push button（operated by
professional）.
（3）Operation test
（a）Press the button indeed，let the hook down untill the limit spring touches the limit switch,the
motor will stop automatically.
（b）Press the button indeed untill the chain is collected into the chain bag completely, and the
motor stops.
c）Test the function of the emergency stop switch (if the optional emergency stop switch is
purchased)Press or button, meanwhile press the emergency stop switch. Check if the hoist
stop running immediately or not after press the emergency stop switch, and make sure the hoist
can not be started again when press this button. Rotate the emergency stop switch clockwise,
make the emergency switch back to the original place. When it bounces back, the hoist can be
started again. If any of tests above is failed, please check the distribution circuit and the automatic
locking of the emergency switch.
（d）Check the lubricating condition of load chain ( the load chain has been lubricated before delivery,
but could be dried when delivery). Any lubricant you have can be used to lubricate the chain. We
suggest that infunde a little of lubricant into the chain bag to protect the load chain.
（e）Check the direction of the chain eyes. All welding points should be of the same direction. The hoist
can not be operated properly and utterly unless all welding chain eyes are in the same line.

2.5 Installation of the trolley
（1）Install the trolley
1）Insert the suspension pin into the lateral plate G and lock it with suspension pin bolts and nuts.
2）Install the suspension pin with adjusting disk.
3）Install the suspension pin into the hanger T. The nameplates of hoist and trolley should be in the same
direction.
4）Install more gaskets into the suspension pin before insert it into the lateral plate S.
5）Install the outside adjusting disk and spacerpin into the suspension pin, and insert the cotter pin into
the spacerpin. When install the spacerpin, check if the cotter pin can be seen at the left side from the
front of the trolley switch box.
（2）Adjust width of the trolley
Please adjust width of the trolley according to below drawing to get appropriate clearance.
Size A is the dimension when two side plates stretch outside completely.
Size A must be approximate B (the width of rail flange) +4mm.
Please adjust size A by increasing or decreasing adjusting disk. Insert the cotter pin into the spacerpin
and bend two branches of cotter pin if the size A is ok.

ELECTRIC CHAIN HOIST
13
The nut must be fixed and strong, insert cotter pin and bend it completely.
（3）Install trolley into the beam.
1）Install the trolley at the end side of the beam and than slip the trolley which has been connected with
hoist already to the appropriate place. This is the most convenient method.
2）If first method is unavailable, please follow drawing 5-9.
a）Unload the brake stopper from hole A on the suspension pin, and insert it into hole B. Insert cotter
pin again and bend it completely.
b）Pull the side plate S and G outside then lift the trolley untill the orbit wheel and orbit surface is in the
same horizontal. Put the orbit wheel of side plate G onto the surface of the orbit.
c）Hold the side plate G and stop it from dropping from the orbit. Push side plate S harder and put its
orbit wheel onto the surface of the girder.
d）Unload the brake stopper from hole B and insert into hole A. Do not forget to bend the cotter pin.
