巻防止装置。 A winch and a boom are installed on the main body of the excavating machine, and the excavating rig is suspended from the lower end of a wire rope that hangs from the winch through a pulley attached to the upper end of the boom, and the excavating rig is prevented from falling.
In an excavation machine that excavates and removes earth by lifting, an electromagnetic switching valve installed in the brake circuit of the winch detects slack in the wire rope of the winch and sends a detection signal obtained at that time to the electromagnetic switching valve. A wire winding prevention device for an excavating machine, comprising a slack detection device that operates the brake device of the winch by switching the electromagnetic switching valve.
