Title: Hydraulic circuit of industrial vehicle
Inventor: ISHIKAWA KAZUO
IPC: B60G17/005
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent damage to a damper by an excessive load without enlarging the damper. SOLUTION: A damper 12 is arranged between a body frame 1a and a rear accelerator 11 to supply and discharge a hydraulic fluid according to the rocking of the rear accelerator 11. A controller C controls the damper 12 so as to lock it as occasion demands and fix the rear accelerator 11 to the body frame 1a. A shut-off valve 13 switches each piping P1-P3 for carrying the hydraulic fluid supplied and discharged from the damper 12 to interrupted state and communicating state according to the control of the controller C. When the hydraulic pressure within the damper 12 reaches a relief pressure in the state where the pipings P1-P3 are laid in the interrupted state by the shut-off valve 13, first and second valves 19, 20 reduce the pressure so that this hydraulic pressure does not exceed the maximum resistant hydraulic pressure of the damper.
