An extendable vehicle jack includes a horizontal frame having a rear section with a front section extendable therefrom. Within the front section is a lifting mechanism including a plate that engages the lower surface of the vehicle as it is being raised and lowered. The lifting mechanism includes a hydraulic pump and cylinder that expand and contract a scissors jack. The front section is automatically extended from the rear section with either a hydraulic or pneumatic cylinder. Accordingly, a worker can position the lifting mechanism any desired location beneath the vehicle frame.

A vertical reciprocating conveyor that can be transported in a storage condition and assembled at a work facility in an operating condition. The vertical reciprocating conveyor includes a carriage assembly that is movable along a pair of spaced vertical rails of a support frame. The carriage assembly includes a pair of spaced uprights and a carriage deck designed to support material moved along the pair of spaced vertical rails of the support frame. The carriage deck is movable between an operating condition and a storage condition, where the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition. The movement of the carriage deck allows the overall size of the vertical reciprocating conveyor to be reduced for shipping.

A powered side panel system is used in conjunction with a loading bed found on trailers and other flatbed vehicles. The system includes a side panel having a vertical member. The side panel is configured to pivot about a panel axis in communication with the trailer. A lever arm extends between the side panel and the trailer. The system includes a reciprocating assembly to operate the lever arm between a lowered and raised orientation. The reciprocating assembly communicates with the lever arm through a cable. The lever arm controls the rate of radial motion of the side panel about the panel axis. A control unit is configured to regulate the operation of the actuator device.

A jack with a protecting structure of a pump piston and a method for using the same are provided. The jack includes a housing, a base located inside the housing, and the protecting structure. An oil cylinder and a pump body are installed on the base. A pump piston is installed on the pump body. A spring is installed on the pump piston and the pump body. A stop protrusion is arranged on the pump piston. The protecting structure includes a dustproof sleeve and a wool felt. The dustproof sleeve is installed on the base and the pump piston. One end of the dustproof sleeve is detachably fixed on the base through a fastener. The other end of the dustproof sleeve is connected to an end portion of the pump piston. The shape of the dustproof sleeve is set into a wavy type.

Disclosed is a vehicle jack device. The vehicle jack device according to an exemplary embodiment of the present invention includes: a base portion in which an inserting hole into which a hinge shaft is inserted is formed and which is supported on a bottom side; a pair of lower arms of which a first portion is installed in the hinge shaft of the base portion in a rotatable way and in which a reinforcing rib is formed in a lengthwise direction; a pair of upper arms respectively installed in a second portion of the lower arm, and on which a reinforcing rib is formed in a lengthwise direction; a bracket member for fixing a first portion of the upper arm in a rotatable way; and a driver installed between the lower arm and the upper arm and providing a tucking driving force to the lower arm and the upper arm. Herein, multiple reinforcing ribs are formed with different heights in a lengthwise direction of the lower arm and wherein the upper arm, the base portion, the lower arm, the upper arm, and the bracket member are made of a plastic material.

The invention relates to an in-ground lifting system and corresponding methods for lifting a vehicle. The lifting system includes: a pit provided with a pit frame; two or more moveable lifting devices configured for moving in the pit; and a system controller configured for defining at least one set of lifting devices for lifting a vehicle.

The present invention provides a tire lifting device that allows an operator to lift vehicle and remove vehicle tires remotely, thereby providing a more efficient and effortless vehicle tire removal operation to the operator. The device is configured to capture, remove, replace, and minutely position vehicle wheel and tire for easy re-installation without involving lifting by the technician. The device further is powered by hydraulic and or electric operation. The device comprises a steel frame with at least at least two fixed wheels, at least one steerable wheel and drives for steering the device over surface. The device further comprises a remote control unit to perform complex motions of the device remotely. A main jack and roller stand raises and lowers the wheel and tire for height positioning, while a support tubes and tire guide hold the tire erect either for removing or remounting the vehicle tire.

A vertical reciprocating conveyor that can be transported in a storage condition and assembled at a work facility in an operating condition. The vertical reciprocating conveyor includes a carriage assembly that is movable along a pair of spaced vertical rails of a support frame. The carriage assembly includes a pair of spaced uprights and a carriage deck designed to support material moved along the pair of spaced vertical rails of the support frame. The carriage deck is movable between an operating condition and a storage condition, where the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition. The movement of the carriage deck allows the overall size of the vertical reciprocating conveyor to be reduced for shipping.

The invention provides a knuckle boom loader having a knuckle boom, an operator seat, and a hydraulic system. The hydraulic system comprises a hydraulic fluid reservoir, a hydraulic pump, and hydraulic fluid lines. The knuckle boom loader further comprises an operator elevator having an elevator platform. The operator elevator has both a lowered position and a raised position. The elevator platform is closer to the operator seat when the operator elevator is in the raised position than when the operator elevator is in the lowered position. Also provided are methods for operating such a loader.
