The answer is: TRUE.

Explanation:

  • The statement describes a typical operation of a crane's hoisting mechanism. When power is supplied to the hoisting motor, it is common for the disc brakes to be released. This allows the motor to transmit power to the gear reducer, which in turn drives the rope drum. This is a standard process in crane operations to lift or lower loads. Therefore, the statement is true.
