A moving body includes a housing, a traction motor, a plurality of elevator motors and a battery. The traction motor allows the housing to travel along a traveling surface. The plurality of elevator motors actuates an elevator unit, the elevator unit being configured to be elevated and lowered with respect to the traveling surface. The battery supplies electric power to the traction motor and the plurality of elevator motors. In the moving body, the plurality of elevator motors, the traction motor, and the battery are distributed when viewed perpendicularly to the traveling surface. The moving body further comprises at least one driving wheel to support the housing on the traveling surface. The plurality of elevator motors, the traction motor, and the battery fall, in a direction perpendicular to the traveling surface, within a range defined by a diameter of the at least one driving wheel.

The present invention relates to a lifting column and a first and second mast for lifting a vehicle, a lifting system including one or more of these lifting columns and a method for lifting a vehicle. The lifting column according to the invention includes a frame provided with a first mast and a second mast; at least one carrier configured for engaging the vehicle, with the at least one carrier moveable relative to the first and second mast; and a lifting mechanism with a drive for moving the at least one carrier and lifting the vehicle. The first and second mast are positioned on the frame at a mast distance, with the mast distance enabling access to a wheel of the vehicle.

The present disclosure relates a device for lifting objects. The device comprises a pair of arms, a horizontal bar, a slide bar, and a housing. The pair of arms are configured to be in an open state to lift an object and in a closed state when the pair of arms are not being used. The device is configured to be elongated to a length for providing ease of loading and unloading of an object. The device further comprises a locking mechanism for providing stability during transit. The housing comprises a roller over a screw for providing easy displacement of the slide bar with respect to the housing.

A lifting structure operating precisely and stably at all stages of a lifting and lowering action includes a lifting assembly and a driving assembly. The lifting assembly includes two first links, two second links, and two seats. A first connecting arm of each first link has first and second ends, the first end having a first gear structure. A second connecting arm of each second link has third and fourth ends, a second and complementary gear structure being provided on the third end. The first gear structures are engaged and the second gear structures are engaged. The second end is rotatably connected to the fourth end through one of the two seats. The driving assembly can drive the two seats towards each other to perform lifting or drive them away from each other to perform lowering.

A fully electric lift device includes a base assembly, a lift assembly, a platform assembly, tractive elements, an energy storage device, and a control system. The lift assembly is coupled with the base assembly and is driven by an electric linear actuator for a lifting function. The platform assembly is positioned at a top of the lift assembly and can be raised or lowered as the lift assembly performs the lifting function. The tractive elements are rotatably coupled with the base assembly and can be driven by an electric wheel motor to perform a driving function. The control system includes a controller that operates the electric wheel motor and the electric linear actuator to perform the driving function and the lifting function using power drawn from the energy storage device. The lift assembly and the tractive elements use only electrical energy to perform the lifting and driving functions.
