Abstract: Loadhandling equipment enables a vehicle to put down on the ground or pick up a load such as a dumpster and to tip the load, which is provided on a front face with a lifting bar. The equipment includes a deformable and tilting handling arm which can assume, in addition to a transport position and a putting down on the ground or picking up position, a tipping position in which a hook interengages with the lifting bar on the load on being pivoted by a tilting actuator about a transverse pivot axis at the rear of the equipment and spaced downwardly from the longitudinal section of the handling arm. The transverse rear pivot axis is behind and under the side members of the chassis frame of the vehicle and the frame of the equipment has an L-shaped profile with a first branch on top of the side members of the chassis frame. An upper portion of the second branch is against the rear of the side members.

Abstract: A device includes a handling structure which has an end portion and a remaining part. The device also includes a driving arrangement which drives the handling structure between (i) a position of transportation in which the remaining part is disposed along a chassis of the vehicle and in which the end portion is at the front, and (ii) a position of picking up a load or placing it on the ground where the end portion is at the rear of the remaining part and behind the vehicle with its free end at a certain height with respect to the ground, in order to cooperate with a load whose gripping means is lower. In addition, the device includes a connecting arrangement which connects the free end of the end portion to the gripping arrangement and a controlling arrangement which controls the distance between the gripping arrangement and the end of the end portion using which the later is attached to the remainder of the handling structure.

Abstract: An apparatus which includes a tilting jack of which the axis on which it is articulated to the tilting structure is in front of the axis on which it is articulated on the frame and in which the tilting structure and the frame are so adapted that the effect of actuating the tilting jack is to cause a lifting hook to tilt about a first transverse tilting axis between a position for starting or finishing tilting and a position for changing the axis, and about a second transverse tilting axis between the position for changing the axis and a position for picking up a load from, or setting down on, the ground.

Abstract: Hydraulic actuators are fed by a single flow-rate generator, each being connected to it through a proportional directional valve, the unit including a device for detecting the highest of the pressures prevailing upstream of the throttle provided by a controlled spool in the respective proportional directional valves, and, in each of these an actuation device to cause the compensating spool to respond to the highest of the upstream pressures thus detected.

Components for locking the lifting cradle to the chassis include a shaft fixed to the chassis and disposed along the vertical axis for pivoting, two attachment arms disposed on either side of a longitudinal plane of symmetry and mounted on the shaft to pivot between an unlocking configuration and a locking configuration, the arms including noses projecting laterally each adapted, in the locking configuration, to engage between two substantially transverse sides of a housing provided on the side beams of the lifting cradle and, in the unlocked configuration, to be outside the housings. Elements to control and guide the movement of the arms and to block the arms in the locked configuration are attached to the arms.

Abstract: Safety valve for a hydraulic circuit supplying a hydraulic receiver having an inlet and an outlet connected to the receiver which includes between the inlet and the outlet a non-return module which has a non-return valve and a selectively operable valve having an unoperated position in which the non-return valve prevents any reverse flow of fluid from the outlet to the inlet and an operated position in which such reverse flow is made possible. A control inlet is provided for applying control pressure to the selectively operable valve. A pressure relief valve is provided between the outlet and the control inlet which is adapted to enable flow from the outlet to the control inlet from a predetermined pressure threshold.

Abstract: A hydraulic valve is adapted to be connected between a pressurized supply line and first and second lines feeding respective first and second circuits with different functions, such as the steering and braking functions of an automobile vehicle. It comprises a first control member adapted to connect the supply line to the first feed line, a two-way distributor device for the second feed line and a second control member adapted to apply to the second feed line a pressure proportional to the force exerted by the user damped by virtue of a dashpot effect.

Abstract: A valve for retaining a jack which retains a drive load. The braking valve includes a pressure reducing valve and safety valve, one of which ensures that the pressure in the chamber is retained, while the other modulates the pilot-control pressure P.sub.p. Thus, at each moment, the pilot-control pressure P.sub.p is adjusted to the value of the retaining pressure P.sub.l.

Abstract: A removable support with a transverse hooking bar for equipping a front panel of a container, having a front panel and an upper panel, to receive a hook of a swinging cross piece bracket, adapted to fit a transportation and handling vehicle, wherein a transverse hooking bar of the movable support receives a handling hook which is connected to the vehicle. The hooking bar is thereby disposed on the front panel, connected to the removable support. The container is locked into place by an eclipsible lock, but at the same time the removable support can be unlocked, allowing access to the front panel of the container. The removable support can pivot about an axis to a horizontal position on the upper panel of the container where it may be locked into place. The support is vertically moveable on the front panel and may be secured at the top or bottom of the panel by means of the eclipsible lock. A swinging door located on the front panel is made accessible by use of the removable support.

Abstract: A proportional type hydraulic distributor incorporates a distributor slide valve including a feed chamber. It is provided with a pressure compensator device for regulating the feed pressure to the feed chamber according to the output (load) pressure of the slide valve. This device includes an inlet channel, an outlet channel communicating with the feed chamber and a stator communicating with the inlet and outlet channels. A compensator slide valve slides in a housing in the stator. A spring exerts an axial force on the compensator slide valve in the same direction as the force exerted on it by the output pressure and in the opposite direction to the force exerted on it by the feed pressure. An annular obturator member on the compensator slide valve isolates the inlet and feed channels and is acted on by a return spring on the compensator slide valve. The latter has a recessed part on which the obturator member slides without clearance.
