Title: Operating reaction force control device
Inventor: HIDAKA YUKIO
IPC: B66D1/44
Filed: 1989-11-10
Abstract: PURPOSE:To securely sense the beginning of movement of a load when the fluctuation of the load is small during the operation of lowering of the load by making the pressure receiving area of an operating reaction force cylinder on the lowering side larger than the pressure receiving area of the other operating reaction force cylinder on the lifting side. CONSTITUTION:When lowering of a suspended load is started, the pressure of an lowering feed side oil passage 32 of a motor 3 is inputted through an oil passage 8' to a reaction force chamber 73' to energize a rod 72' to project and allow the projecting force to act as an operating reaction force on an operation unit 62' on the lowering side of a lever 6. In this case, the load pressure during the lowering operation is low and the region of pressure change is small, but control gradient of lowering operating reaction force becomes larger than the control gradient of lifting operating reaction force because the pressure receiving area A' of a piston 73' on the lowering side is set larger than the pressure receiving area A of a piston 73 on the lifting side. Very small changes in the lowering load pressure are thus converted into the changes in large operating reaction force, and these changes can be sensitively sensed through a lever 6 by an operator.
