The invention relates to a suction excavator having a vehicle chassis, a suction fan, and a dumpable material collection container. The material collection container has a collection chamber and is swivelable about a tilt axis that extends parallel to the vehicle longitudinal axis, between a working position and an emptying position. Furthermore, a filter unit is provided which is situated in a filter chamber in the material collection container and through which suction flow passes. The filter unit is rotatably mounted on a rotational axis that extends parallel to the tilt axis of the material collection container, wherein in an unlocked state, swiveling of the filter unit about the rotational axis is enabled in order to swivel the filter unit out of the filter chamber, at least in sections.

A dump trailer and system for a semi-trailer truck are disclosed. The dump trailer and system includes a tub, a coupling plate configured to engage the dump trailer to the tractor, a first hydraulic cylinder hinge, a second hydraulic cylinder, and a draft arm attached to the coupling plate and the tub that cooperate to improve manufacturing economics and/or dumping of a load carried by the dump trailer.

A collar for a telescopic cylinder with a cap includes the terminal portion of the cap that presents the opening of the cap, such that the collar includes in the following order a first annular element with a contoured profile, which surrounds the terminal portion and is welded thereto, and a second annular element, which can move with respect to the terminal portion and to the first annular element.

The collar further includes an O-ring, made of rubber, surrounding the terminal portion and a third annular element surrounding the terminal portion and welded thereto.

The first annular element has, at its internal circumference, an annular guide with a curved internal circumferential surface, the internal circumferential surface having, at each point of its circumference, a vertical cross-section with a shape that is concave as it progresses toward the outside of the collar.

A dump trailer and a hydraulic cylinder assembly for the dump trailer are described herein. The cylinder assembly includes a first barrel, a second barrel rigidly coupled to the first barrel along a longitudinal axis of the cylinder assembly, and a piston assembly. The first barrel includes an inlet port for receiving vehicle hydraulic fluid and an outlet port for providing the vehicle hydraulic fluid to the vehicle. The second barrel includes an inlet port and an outlet port for providing dump trailer hydraulic fluid to a hydraulic lifting mechanism of the dump trailer. The piston assembly includes a first piston and a second piston coupled to the first piston by a shaft. The piston assembly is configured to provide the dump trailer hydraulic fluid to the hydraulic lifting mechanism to lift a box of the dump trailer when the cylinder assembly receives hydraulic fluid from the vehicle.

An agricultural dump cart including a frame, ground conveyance devices carrying the frame, a dump bed, a dumping mechanism and at least one live wall mechanism. The dump bed is coupled to and carried by the frame, and the dump bed has a non-dumping position and a dumping position. The dumping mechanism is connected to the dump bed, and is configured to move the dump bed between the non-dumping position and the dumping position. The at least one live wall mechanism is operatively located along a side of the dump bed. The at least one live wall mechanism is configured for moving a crop material out of the dump bed.
