ANTI-TIPPING DEVICE OF EXCAVATOR

摘要

means (1) for sensing a weight of a material which is to be lifted by the excavator; means (2) for sensing an operating position and an operating speed of the actuator; means (3) for sensing a tipping angle of the car frame of the excavator, and an alarm driving circuit (5) electrically connected to an output port of the controller so as to drive a buzzer (6) and an alarm lamp (7) each electrically connected there to upon receiving an electric alarm signal from the controller. The operator is alarmed to overweight of the material to be lifted in case of sensing the lift weight of the material over a level. And the lifting operation of the excavator is stopped irrespective of the handling of the operator in case of sensing an overweight over another level capable of tipping the excavator.
