Abstract
Improvements in lifting systems for truck boxes, characterized in that they comprise a fluid control pump of a tank, through a distributor, equipped with a pressure valve, which has one of its positions, a step of fluid to a driving piston, in whose displacement it sends the same impulse or, at least, four connected pistons that transmit the pressure to the lower chamber of as many double-acting pistons, placed under the truck's box, while in another position of the distributor, the fluid passes through a duct to the upper chamber of the double-acting cylinders, at which time these lower dragging in their movement to the box of the truck, and because the front part of the driving piston, for where the fluid penetrates, it is in communication with the valve that regulates the stroke of the driving piston, so that when the maximum displacement of the piston takes place, in operation the valve passes through it a quantity of fluid towards a return pipe to the tank.
