Spring-Set Hoist Brake Test Procedures
The following are recommended methods for spring-set
brake testing. Consult the crane manufacturer for additional
information relative to the proper method and desired torque
ratings.
1. Apply torque with a suitable torque wrench at the end
of the shaft for hoists with an integral motor and brake.
2. For hoist with a band brake or internal load brake
detach the motor without disconnecting the non-mechanical
lines. Apply torque with a suitable torque wrench at
the exposed countershaft end.
3. Power hoist motor with the brake applied.
