A vehicle system includes a chassis and a lift assembly. The chassis includes a frame defining a first aperture and a second aperture. The lift assembly includes an adapter assembly and a lift device. The adapter assembly includes (a) an adapter defining a first pin aperture, a second pin aperture, and an adapter aperture, (b) a first pin extending through the first aperture and the first pin aperture and a second pin extending through the second aperture and the second pin aperture to selectively couple the adapter to the frame, and (c) a cross member configured to be received by the adapter aperture. The lift device includes a pair of receivers configured to engage the cross member of the adapter assembly to support the cross member. The first pin aperture and the adapter aperture each extend laterally when the adapter is coupled to the frame.

A jack stand includes a base having a jacking surface which receives a jack thereon, in which the jack has a main body and a lifting head which can be jacked up. Two support columns extend perpendicularly upward from the base parallel to and spaced apart from one another by a fixed lateral spacing to receive the jack therebetween. A jack body is slidably supported along the two columns and includes a jacking surface on a bottom side thereof so as to be arranged to operatively receive the jack between the two jacking surfaces of the jack body and the base respectively such that operation of the jack displaces the jack body relative to the base. A jack post, upon which an object to be jacked is supported, is slidably supported on the jack body to be adjustable in height independently of a height of the jack body.

An oil pressure mobile device for a wood working machine is provided in a wood working machine, including a power mechanism and a lifting mechanism. The power mechanism is provided with an oil hydraulic cylinder having its inner wall annularly mounted with a piston fixed with a telescopic rod. The lifting mechanism is disposed with two wheel pressing plates at the underside of the wood working machine. The two wheel pressing plates are jointly provided with a connecting link connected with the telescopic rod, and respectively installed with a moving wheel. Thus, the telescopic rod is driven by the power mechanism to extend or retract and actuate the wheel pressing plates to produce angular variation to make the moving wheels stretch out of the housing of the wood working machine for facilitating shifting of the wood working machine with less labor.

A lift device includes a chassis, a boom pivotally coupled to the chassis, a first leveling assembly pivotally coupled to a first end of the chassis, a second leveling assembly pivotally coupled to an opposing second end of the chassis, and a control system. The first leveling assembly includes a first pair of actuators positioned to facilitate a first pitch adjustment and a first roll adjustment of the first end of the chassis. The second leveling assembly includes a second pair of actuators positioned to facilitate a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis. The control system is configured to (i) actively control the first pair of actuators and the second pair of actuators during a first mode of operation, and (ii) actively control the first pair of actuators and facilitate passive control of the second pair of actuators during a second mode of operation.

A lift arm of a floor jack is composed of a number of components made from metal bar stock. The lift arm is adapted to transfer power and motion from a power unit to a saddle, which is adapted to be placed at a lift point of the vehicle, thereby applying pressure to the lift point and raising the vehicle.

A wheel lift comprises a frame having ground engaging elements, a four bar linkage structure supported by the frame, lifting arms extending from the four bar linkage and for receiving and supporting a wheel and a handle for operating the four bar linkage to raise and lower the wheel. The frame defines an open space for receiving a wheel, for example a vehicle wheel. The lifting arms may be raised and lowered and locked in position to aid in removing and/or mounting vehicle wheels.
