SWING SAFETY DEVICE FOR EXCAVATOR

摘要

PURPOSE: A rotation safety device for an excavator is provided to reduce crash accidents by generating vibration at a rotation controlling lever according to distances with obstacles to inform a driver of danger. CONSTITUTION: A rotation safety device for an excavator(1) comprises a motion sensor(110), a control unit(120). A signal unit(130), and a power supply unit(140). A plurality of motion sensors is installed at an edge of an upper rotator(20) and a front attachment(10) of the excavator. The control unit generates an electrical signal according to access of obstacles in rotation of the excavator. The signal unit generates vibration at a rotation controlling lever with the signal of the control unit. The intensity of the vibration is controlled according to distances of the obstacles.
