Abstract

Remote control for hydraulic cranes, characterized because, being applicable preferably to hydraulic cranes governed by spring-centered valves that control the hydraulic actuation of the functions of the crane, including generally horizontal movement, extension or deployment and lifting of the boom and unwinding and dragging the crane cable, comprises remote control means for driving the control valves of the crane, including a master cylinder for each control function, with its piston position sensitive to manual control by means of a control lever, slave cylinder for each master cylinder, and identical to it, including holes on opposite ends, in direct and constant communication with the holes of the opposite ends of the corresponding trail cylinder, and with a piston hydraulically coupled to the piston of the said master cylinder, to reflect its movements, said cylinder piston being slave, mechanically coupled to the corresponding control valve of the crane, so that the movement of the said control element, relax the movement of the control lever of the master cylinder.
