    Abstract: A camper jack for mounting on a camper body, the jack having an extensible leg projectable from a hollow jack housing and attached to the camper body along the length of the housing. A piston cooperating in a cylinder in the extensible leg extends the leg from the housing. A hydraulic fluid reservoir is formed in the extensible leg in an annular space surrounding the cylinder. A valve block is coextensive with the extensible leg at the foot of the leg and contains the valves and pumping piston for the jack. Valving in the valve block permits manual extension and retraction of the extensible leg. Grooves are provided in a novel needle valve allowing control of the rate of flow of the hydraulic fluid. Pumping motion is controlled by a pump handle receiver.

    Abstract translation: 一种用于安装在露营器本体上的露营器插座，所述插座具有可从中空千斤顶壳体移出并且沿着所述壳体的长度附接到所述露营器本体的可伸展腿部。 协作在可伸缩腿中的气缸中的活塞将腿从壳体延伸出来。 在可伸缩的腿部中，围绕气缸的环形空间形成有液压流体储存器。 阀块与腿部的可伸缩腿共同延伸，并且包含用于千斤顶的阀和泵活塞。 阀门阀门允许伸缩腿的手动伸缩和缩回。 在新颖的针阀中提供槽，允许控制液压流体的流量。 泵送运动由泵手柄接收器控制。

    Abstract: The invention relates to a semitrailer (1) comprising devices (6) for shifting a load, such as a container (9), to the support of the trailer (1) and away from the support thereof; as well as devices (3) for shifting the bogie (2) in the lengthwise direction of the trailer. According to the invention, the trailer (1) comprises devices (10; 12) for raising and lowering both the front end (1a) and rear end (1b) of the trailer. By employing the said devices, the front and rear ends of the trailer can be raised and lowered irrespective of each other in order to load and unload the trailer.

    Abstract: The frame of a load-bearing vehicle has two beams extending one on each side of the frame and pivotally mounted to the frame. Between each beam and the frame is an air bladder, or other cushion. At the end of each beam is a linkage carrying a tag axle, wheel and tire. A power actuator rotates the linkage to bring the wheel and tire into ground engaging position at the end of the beam, and a second power actuator pivots the beams upwardly to raise the wheel-and-tire set; or pivots the beam downwardly to lower the wheel-and-tire set into ground engagement. Fluid motor actuators for the linkages and the beams respectively, are remotely operable so that the extra flotation wheels and tag axle can be brought into ground engagement when additional ground support is desired for the weight borne by the vehicle frame; or, the extra flotation wheels and tires can be raised to an elevated transport position, also by remote operation of the fluid motor actuators associated with the beam and linkage respectively.
