Replace the contactor of the
direction

(2)

Replace the push-button of the
direction

23. Motor has burnt

(Main hoist, trolley, end-
carriage)

(1)

3 phase sequence are not correct
(a contacting point of a phase is
failed)

(2)

Short-circuit (motor wiring error)

(3)

Over-loading (heavier than its
capacity, and/or overtime)

(4)

Electric breakdown due to
overheating, incurs a short-
circuit between phases (over
duty cycle)

Contact the supplier or the regional
distributor

24. The gear box has
abnormal noise

(1)    Bearing trouble
(2)    The planetary gear or inner gear
          is worn
(3)

The gear-shaft is bent or
deformed

Contact the supplier or the regional

25. The motor has abnormal
sound
(main hoist, trolley, end-
carriage)

(1)

The bearing is scuffed

Contact the supplier or the regional
distributor

26. Abnormal sound when
the end-carriage is
traversing

(1)

The bearing of trolley wheel is
worn (driving wheels or driven
wheels)

(2)

The front and rear wheel are not
in the same line

(3)

The trolley rail is bent or
deformed

Contact the supplier or the regional
distributor

27. Abnormal sound when
the end-carriage is traveling

(1)

The bearing of end-carriage
wheel is worn (driving wheels or
driven wheels)

(2)

The front and rear wheel are not
in the same line

(3)

Span or girder is deformed,
causing an over-loading

(4)

The specification of rail has not
met its standard. For example
five-ton hoist uses a rail for
three-ton hoist

Contact the supplier or the regional
distributor

28. Oil leaking from gear
box

(1)
