ABSTRACT:
The present invention is directed to mechanical handling machinery and equipment or load handling devices (manipulators).
The device of the invention comprises a housing accommodating a number of distributors made as spring-opposed directional control spool valves movable from an actuating member. One group of the control spool valves forms an angle with the longitudinal axis of the actuating member, while the other group has one arranged coaxially with the longitudinal axis of the actuating member, and the other valve is situated lengthwise of the axis.
The actuating member has two articulately interconnected levers of which one is provided with a knob and a ring for cooperation with one of the control spool valves in the first group of the directional control spool valves. The other lever is locked-in with the control spool valve arranged coaxially therewith and is provided with a pinion which is kinematically associated with the other control spool valve in the first group of the directional control spool valves.
In order to impart motion to the control spool valve arranged lengthwise the longitudinal axis of the actuating member, provision is made in the housing for an additional pinion to interact with the gear racks with which the control spool valves of the second group of the directional control spool valves are provided.
