Abstract

PURPOSE:To prevent the instant lowering of a boom during switching period as well as suppress the occurrence of vibration during traveling of vehicle by a method in which an accumulator is connected through a mode-switching valve and a reducing valve to an oil-pressure cylinder for operation by an outside pipe. CONSTITUTION:An accumulator 19 for suppressing vibration is set through a mode-switching valve 18 and a reducing valve 20 on the auxiliary load holding side oil chamber 8a of an oil-pressure cylinder. A throttle valve 31 is also pro vided on the primary side of the valve 20 as needed. The valve 18 is designed to be switched to an interruption position (operation mode) or to a communica tion position (traveling mode). The comfortable ride feeling can thus be im proved by reducing vibration during traveling, and the safety during operation can also be raised due to smooth suppression of the vibration of the accumula tor.
