How do bridge overhead travelling cranes supply power ?

The flexible cable is the first option. An AC power source provides power to the hoisting overhead travelling crane. Because the overhead travelling crane's job is movable, the overhead travelling crane and the power cannot be connected in a fixed manner. Typically, the flexible cable is utilized to supply power. As the overhead travelling crane system and trolley move down the track, the flexible cable can stretch and roll. A sliding wire and an electric brush are used in the second procedure. Three phase AC power is fed to the cabin's protection box through three main slide wires and an electric brush, and then to the overhead travelling crane system's motor, electromagnet, and AC control station via wire route.
