A transportation assembly for transportation of an object on a surface comprises at least four rolling devices, a transportation body and at least one interface element for each rolling device. The interface element is adapted for connecting the rolling device to the transportation body. The interface element for mounting or integration of a rolling device to/into an object comprises an upper part and a lower part, where the upper part and the lower part comprise complimentary shaped guiding means.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.

An apparatus configured to convert between a cart and a lounge chair comprising a bottom portion, backrest portion, a leg rest portion, first and second removable side portions. The backrest and leg rest potions rotatably coupled to the bottom portion and movable between open and upright positions. The first and second removable side portions being coupled to the backrest and leg portions when in the upright positions, wherein an open carton of the cart is formed by the bottom portion and the leg rest and backrest portions when in the upright positions, and the first and second removable side portions when connected to the leg rest and backrest sides, and the leg rest and backrest portions, when in the outward positions, form a seat, a leg rest and a backrest of the lounge chair, respectively, the lounge chair being configured to support a person in a sitting or lounging position.

A service table for transporting a battery pack comprises four frame members arranged end-to-end in a circuit, four hinges between adjacent frame members, and wheels. The service table further comprises a support bed mounted to at least one of the frame members and configured to support the battery pack. At least one hinge lock is disposed between adjacent frame members and arranged to be rigidly fixed to both of the adjacent frame members in a locked configuration and arranged to be decoupled from at least one of the adjacent frame members in an unlocked configuration. The frame members are arranged in a service configuration having a first width when the hinge lock is arranged in the locked configuration for transporting the battery pack thereon and in a storage configuration having a second width, less than the first width, when the hinge lock is arranged in the unlocked configuration.

A height adjusting structure includes a coupling member configured to couple a caster to a casing, and the coupling member has a fixing part to which the caster is fixed, an extended part extended upward from the fixing part and penetrating through a bottom wall of the casing, and a meshing part formed at a portion within the casing on the extended part and having a plurality of engaging portions aligned at a predetermined pitch in a vertical direction. The height adjusting structure further includes a restraining member meshing with the meshing part formed on the extended part to restrain the extended part so that the extended part is unable to move vertically.

A reusable handling device is specially designed for transporting components of a checkout station to a location within the store where the checkout station is installed. The handling device includes casters and is designed to removably mount to a checkout station component (e.g., bagger) having adjustable feet when there is a need to move or transport the checkout station component (e.g., during installation). Generally, the handling device is configured to extend between and engage two of the adjustable feet of the checkout station component. Two or more handling devices can be mounted to the checkout station component to move the checkout station component during installation and can be removed when finished. After the installation is complete, the handling devices can be returned to the manufacturer or supplier of the checkout station component for use in another installation.

This application relates to a wheel steering angle adjustment device for a vehicle operated by manpower. The device may include a fixed body including a rotation support, a rotation body, a lift member coupled to the rotation support, a locking switch coupled to the lift member, and a plurality of fixing groove portions in the outer peripheral surface of the rotation support. The device may also include a fixing protrusion protruding from the locking switch and configured to be detachably coupled to the fixing groove portions, a rotation range limiting stopper provided on a lower portion of the lift member, and a rotation guide groove portion provided concavely in an upper surface of the rotation body. As the rotation range limiting stopper becomes stuck on an end portion of the rotation guide groove portion, an angle by which the rotation body is rotatable relative to the fixed body is limited.

A modular fork assembly for a pallet truck includes a discrete elongate body, a discrete load wheel module, and a discrete fork tip that may be detachably connected by the same or different types of interlocking mechanisms that are adapted to inhibit sheer forces. The load wheel module includes a frame and a load wheel assembly that includes a load wheel that is operatively connected to the frame.

An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.
