GRAB BUCKET EQUIPPED WITH COLLISION PREVENTING DEVICE

摘要

PURPOSE: A grab bucket equipped with a collision preventing device is provided to improve the driving efficiency of a crane without a direct operation of a driver by automating the process of gathering and carrying wastes. CONSTITUTION: A collision preventing device comprises:the sensor(6) for detecting a distance; a sensor bracket(7) for fixing and supporting the sensor(6); a sensor cable(10) connected to the sensor(6); a protective tube(8) for wrapping the sensor cable(10); the sensor cable(10) connected to a crane control unit, so the signal corresponding to a critical height which is previously settled input; the sensor cable(10) preventing a high speed collision with wastes(4) and a grab bucket(3) even in case of a manual driving by a driver by braking a rope(2)connected with the grab bucket(3).
