Provided is a rear axle movement device for a truck with a lowerable bed, comprising: a front axle, a driver's cab, a rear axle, a cargo container, a sub-frame, a first lifting device, a second lifting device, a first guiding device, a second guiding device, and an electric motor. According to the present invention, the rear axle movement device utilizes a chain and a sprocket.

In a vehicle lift device (100) including a pair of right and left lifting frames (10) installed on right and left sides of a maintenance work area (A) of a vehicle to be serviced (1), and a pair of front and rear swing arms (20, 50) supported at two respective front and rear positions of a lifting platform (11) included in each of the lifting frames (10), and allowed to be lifted and lowered along with the lifting platform (11), each of the swing arms (20, 50) includes a link coupling body (20A, 50A) obtained by connecting a plurality of links, a base link (21, 51) included in the link coupling body (20A, 50A) is fixed to the lifting platform (11) of the lifting frame (10), and a distal link (22, 52) included in the link coupling body (20, 50A) includes a vehicle holding tool (30, 60).

An electrically powered gear box for a semitrailer stabilizer, comprising a gear box housing; the housing is internally provided with a drive gear (10), a power output shaft (2), and a clutch mechanism ensuring transmission connection or disengagement between the drive gear (10) and the power output shaft (2); the housing is externally provided with a motor (20); and the shaft of the motor is in a transmission connection with the drive gear (10). The electrically powered gear box for the semitrailer stabilizer can be manually or electrically controlled. In the case of electrical control, the clutch mechanism causes the drive gear (10) to be in a transmission connection with the power output shaft (2); upon activating the motor (20), the motor (20) drives the power output shaft (2) to rotate via the drive gear (10) and the clutch mechanism, thus ensuring easy operation. In the case of manual control, the clutch mechanism causes the drive gear (10) and the power output shaft (2) to disengage from power, such that the power output shaft (2) can be rotated by turning a handle (9), thus being usable in the absence of a power source.

A system for supporting a vehicle. The system may include a vehicle jack in mechanical communication with a jack foot and a striker plate. The jack foot is rotatable relative to the vehicle jack on a rotation axis disposed on the vehicle jack and perpendicular to a long axis of the vehicle jack. The jack foot includes a base at a distal end of the jack foot. The jack foot also includes a cam surface at least in part at a proximal end of the jack foot. The cam surface is aligned with the striker plate and interacts with the striker plate to rotate the jack foot in response to movement of the vehicle jack from a lowered position to a raised position.

A camper that is hauled by a vehicle. The camper is collapsible into a compact easy traveling position that is connected to a hitch receiver on the vehicle. The camper in the collapsed travel position fastened to a vehicle hitch does not have any wheels making contact with the roadway or ground. The camper in its collapsed position has an equal or higher ground clearance as the ground clearance of the vehicle it is attached to so as not to encumber off-road or roadway travel. The camper is not mounted on a trailer and does not require a trailer.
