Control block to position platform on goods vehicle - gives combination of rapid movement and braking functions

摘要

The control block is used to actuate several hydrualic drives. It has directional flow valves of which one valve has a braking piston in a bore in the control piston. The rapid movement valve (54) is built into the valve control block (50) and hydraulically parallel to the directional control valve (52) so that on operating the rapid movement valve the directional control valve is reset in the neutral position. USE/ADVANTAGE - Control for the swivel cylinder of a load-carrying platform on a goods vehicle which combines a braking function and a rapid movement valve within a single valve block.
