Abstract
포크를 미리 설정된 자세로, 소망하는 때에 자세를 제어할수가 있는 포크틸트 동작 자동정지장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a fork tilt motion automatic stop device capable of controlling the posture when the fork is in a preset position when desired.
포크(3)의 기울음 각도를 검출하는 틸트각센서(14)를 가짐과 아울러 틸트레버는 틸트동작 자동 정지/해체 모드 절환용 누름버튼스위치(14)를 가지며, 연산처리장치(25)는 상기 틸트각 센서가 출력하는 포크틸트각 θ를 감시하며, 상기 누름버튼스위치가 틸트동작 자동정지모드신호를 출력하고 있는 동안은, 상기 포크틸트각이 미리 상기 연상처리장치의 메모리부(26)에 설정된 포크틸트각 θ0와 일치한 때에 상기 틸드실런더에의 압액 공급을 정지시킴을 특징 으로 한다.In addition to having a tilt angle sensor 14 for detecting an inclination angle of the fork 3, the tilt lever has a push button switch 14 for automatically switching the tilt operation / release mode, and the arithmetic processing unit 25 is The fork tilt angle is monitored by the tilt angle sensor, and the fork tilt angle is set in advance in the memory unit 26 of the associating apparatus while the push button switch outputs the tilt operation automatic stop mode signal. It is characterized in that the pressurized liquid supply to the tilt cylinder is stopped when the fork tilt angle θ 0 coincides.
