Traction wheel, brake shoe and brake wheel are usually the only components that will wear.
Among them, the brake wheel is most unlikely to wear. Brake pads are more likely to wear but
can be monitored with feeler gauges. Refer to the brake section of this manual for brake
inspection procedures.
The winding working temperature of traction machine shall not exceed 130
℃
. It can be
controlled by the thermal switch in the main machine. When the temperature reaches 130
℃
,
the traction machine shall be stopped.
When the traction machine rotates under the passive condition, it will be in the state of power
generation. At this time, high voltage will be generated at the host terminal. Attention shall be
paid to avoid electric shock and equipment damage.
Grease and other impurities shall be avoided between the brake pad and the brake wheel to
avoid the decrease of braking force of the brake system. If the residual thickness of the brake
pad is less than 5 mm due to wear, the brake pad shall be replaced.
Traction wheels are the most likely item on the machines to wear. Periodic measurements of
rope depth and the evenness of wear for all ropes (groove depth should wear evenly) should
be monitored. Cable should not be more than 0.125 inch (1/8”) below the outer rim of the
traction wheel. If cable(s), are below 0.125 inch, or if wear is uneven, replace the traction
wheel and cables.
Check machine guarding and rope retainers for clearance and attachment hardware for
tightness. Adjust as necessary.
