Troubleshooting 

Remarks 

Suspended  platform 

slides down in static 

condition

 

1. Motor electromagnetic brake fails. 

2.  The  spacing  between  brake  and 

armature is over too big.

 

1.

 

Replace 

electromagnetic 

brake. 

2. Adjust the space.   

 

See 

5.1.3   

 

Suspended  platform 

cannot 

stop 

in 

ascending 

The  main  contact  point  of  AC 

contactor disengages. 

Press emergency stop button or 

pull the limit switch to stop the 

moving 

of 

the 

platform, 

replace the contactor. 

 

Control button fails. 

Press emergency stop button or 

pull the limit switch to stop the 

moving 

of 

the 

platform, 

replace the control button. 

 

Suspended  platform 

cannot 

stop 

in 

descending 

The  main  contact  point  of  AC 

contactor  disengages  or  the  control 

button fails. 

Press emergency stop button or 

pull the limit switch to stop the 

moving 

of 

the 

platform, 

replace the contactor or control 

button. 

 

The  electromagnetic  brake  is  out  of 

order: 

1.

 

The 

space 

between 

the 

electromagnetic 

disk 

and 

the 

armature is too big. 

2.

 

Too small contact area between the 

friction disk and the armature. 

3.

 

Slipping  between  the  friction  disk 

and  the  armature  because  of  the 

water or oil. 

4.

 

The  steel  rope  is  slipping  in  the 

hoist. 

1.

 

Adjust  the  space.  If  it  is 

can’t  be  done,  replace  the 

brake disk. 

2.

 

Check  if  the  space  between 

the  friction  disk  and  the 

armature  is  well-distributed; 

otherwise,  replace  the  disk 

or the armature. 

3.

 

Clean. 

4.

 

Repair the hoist. 

See 

5.1.3

   

 

Suspended  platform 

cannot  ascend  and 

descend 

Power supply is abnormal: 

1. Leakage breaker disengages. 

2. Phase lacking. 

1. Check to see if any leakage, 

and 

take 

preventive 

measures. 

2.  Check  if  the  3-phase  power 

is normal and reconnect. 

 

Failure of control line: 

1.

 

Control  transformer  or  control 

button damaged. 

2.

 

Thermal  overload  relay  breaks  or 

damages. 

3.

 

Universal  switch  not  in  good 

contact. 

1.

 

Replace. 

2.

 

Wait  3-5  minutes  before
