Claims

[Scope of utility model registration request]

By operating a hand switch attached to an operating cable suspended from a hoist that runs along the girder or a moving body installed separately from the hoist, the running of the girder and the hoisting up, down, and traverse are controlled. In the overhead crane, the hoist or moving body is provided with a switch that is normally opened by a spring and closed by pulling a rope connected to the hand switch, and the terminal of the switch is connected to a power cutoff device, When the garter or the hoist, or both, malfunctions due to equipment failure, such as runaway, the switch closes by pulling the rope downward, and a power cutoff device is activated to turn off the power. An emergency stop device for overhead cranes.
