The present invention provides a vehicle leveling device with an upper arcuate support presenting a substantially planar surface and a lower support with an arcuate groove configured for rotational receipt of the upper arcuate support opposite said substantially planar surface, a rotational axis aligned with the arcuate groove and extending between a front and a rear associated with the upper arcuate support and parallel to the substantially planar surface; the upper arcuate support configured for rotation about said rotational axis.

A floor jack locking assembly is presented. The locking assembly may include a locking pin used to mechanically lock out the jack at a specified lift height. The locking assembly may avoid the hydraulic lift cylinder being the only stabilizing component of the jack when supporting a significant load. The locking pin may be coupled to lifting link arms, avoiding the need to have the locking pin inserted into or through the lifting arm of the jack.

A rotating container dumper includes a bin assembly having at least one opening configured to receive a container, a frame that is configured to receive the bin assembly, and a linkage system that is operably coupled to the frame and the bin assembly. The linkage system is configured to rotate the bin assembly between a home position and a deployed position. In the home position, the bin assembly is disposed within the frame and a first opening of the at least one opening is positioned at a top of the bin assembly. In the deployed position, the bin assembly is disposed outside of the frame and the first opening of the at least one opening is positioned at a bottom of the bin assembly.

A camera dolly includes a folding arm having a lower end of a first arm section pivotally attached to the chassis, and a lower end of a second arm section pivotally attached to an upper end of the first arm section. A hydraulic system includes a pump, an accumulator and a hydraulic cylinder connected to the first arm section. An arm drive system in the first arm section rotates the second arm section relative to the first arm section. The arm drive system may use chains and sprockets. An electrical system includes a battery contained within a lower rear opening of the chassis. The motor and an AC to DC converter are electrically connected to a motor mechanically connected to the pump. The pump is operated by the motor, and the motor is electrically powered by the battery and/or the AC to DC converter.

A jack has a lifting post, a pair of side legs, adjustable leg extensions, and leg locking mechanisms for locking the leg extensions with respect to the side legs. The lifting post has a bottom element and a top element that slide with respect to each other, and a vehicle engaging hook mounted on the top element. A lifting mechanism lifts the top element with respect to the bottom element, once the side legs have been adjusted.

A method of retrofitting a trailer having a crank jack with a jack housing and a jack leg into a hydraulic jack includes removing mechanical components from within the jack housing, the mechanical components comprising gearing of the crank jack, placing a hydraulic cylinder within the jack housing, wherein the hydraulic cylinder comprises a main cylinder and a ram piston extending outwardly therefrom as the main cylinder is filled with pressurized fluid, securing the hydraulic cylinder by fastening a top portion of the hydraulic cylinder to the jack housing using a fastener inserted through a hole in a platform positioned within the jack housing, and further securing the hydraulic cylinder by fastening the ram piston to the jack leg using a bolt extending through a pre-existing hole in the jack leg.
