IPC: B66F19/00
Filed: 1990-06-20
Abstract: PURPOSE:To manually conduct only the switching operation of an operation valve manual and simplify the operation by providing such a constitution as automatically switching a weight memory valve to manual mode when an actuator is raised and lowered by the operation valve, and to balance mode when the operation valve is in the neutral position. CONSTITUTION:An operation valve 6 is switched to any of three positions 6a, 6b, 6c. The position 6a is an up position, the position 6b is a neutral position, and the position 6c is a down position. A weight memory valve 7 is switched to two positions 7a, 7b. When a pressure oil is guided to a pilot port 7c, the weight memory valve takes the position 7a, but when the pressure of the pressure oil of the pilot port 7c is lowered, it is automatically shifted to the position 7b by the force of a spring 7d. When the operation valve 6 is in the neutral position, the weight memory valve 7 takes balance mode as the pressure of the pilot port is removed. When the operation valve 6 is in the position 6a or 6c, the weight memory valve 7 is automatically switched to manual mode since the pressure oil is guided to the pilot port 7c through a pipeline 24.
