MOUNTING STRUCTURE OF LIVE-LOAD-DETECTING PRESSURE SENSOR OF FORK LIFT AND FORK LIFT

摘要

PROBLEM TO BE SOLVED: To make it easy to prevent early deterioration and loss of functions by resisting impacts and thermal impacts from the outside during cargo handling operations. SOLUTION: Hydraulic fluid is supplied to and discharged from the oil chamber 16r of a right lift cylinder 16R and the oil chamber 16l of a left lift cylinder 16L via a flow regulator 37 assembled and fixed to the cylinder bottom of the right lift cylinder 16R. A pressure sensor 32 is provided within a space portion 30 in a vehicle body 11 isolated from the outside. A high-pressure hose 42 having one end assembled and secured to the cylinder bottom of the left lift cylinder 16L and communicated to the oil chamber 16l and extended from a mast 13 to the vehicle body 11 is connected to the pressure sensor 32 at the other end. Hydraulic pressure closer to the oil chambers 16r, 16l than to the flow regulator 37 is introduced into the pressure sensor 32.
