A transportation dolly can have a frame, two axles pivotally coupled with the frame, each axle having two distal ends and a wheel assembly coupled at each distal end and a synchronous steering system. The synchronous steering system can include an intermediate link pivotally coupled with the frame, the intermediate link having a two distal ends, and a first push-pull rod coupling one of the two axles with the intermediate link, and a second push-pull rod coupling the other of the two axles with the intermediate link. The first push-pull rod is coupled to one distal end of the intermediate link and the second push-pull rod is coupled to the opposing distal end of the intermediate link. The first push-pull rod, the second push-pull rod, and the intermediate link provide counter phase synchronous pivoting of the two axles relative to the transportation dolly.

A collapsible, motorized cargo cart includes an electric motor and a foldable frame that folds down flat for storage and transport. The frame member includes upper and lower frame portions in pivoting relation, and they can be positioned and locked at any desired angle with respect to each other. The lower frame member includes an extension that may be extended or retracted, as desired. Handlebars are provided on the upper frame member, and a throttle controls the speed of the cart, which is capable of transporting at least 300 pounds over rough terrain. Two large wheels are positioned on either side of the cart, and a removable caster wheel may be attached to a front portion of the frame. An electric motor and rechargeable battery are disposed on an underside of the frame's lower portion, and include a drive assembly to power the side wheels.

A hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform. A platform enclosure is also disclosed.

A folding handcart includes: a main body provided with a supporter configured to extend vertically from a lower portion thereof; and a loading plate provided with at least one loading plate wheel unit, connected to the supporter of the main body through a hinge unit, folded while being rotated toward the main body by the hinge unit, and stowing an article or a folding box, wherein, when the loading plate is folded while being rotated toward the main body, a predetermined stowing space is provided between the main body and the loading plate in accordance with an area of the supporter such that the folding box is folded and stowed therein.

A device and method of using a Multi-functional utility cart comprising a base, an axle and wheel assembly, a lower structure, and an upper structure, wherein said axle and wheel assembly are attached to base, base is pivotally attached to lower structure, two upper structural vertical tube frames are slide ably connected to two lower structural vertical tube frames, a rotational tray connected to the upper vertical structural tube frames, a foldable base is connected to the two lower structural vertical tube frames; wherein a user elects to collapse said multi-functional utility cart for easy storage and folding, wherein user would minimize the size of said collapsible frame by sliding two upper vertical tubes into two lower vertical tube frames and user would fold up said base; and wherein said multi-functional utility cart has four types of wheel designs and locations that can be utilized for different tasks.

A cart includes a fixed platform having a first edge and a first top surface for carrying cargos, a foldable platform having a second top surface for carrying cargos and a second edge pivotally attached to the first edge, the foldable platform pivoting between a horizontal position and an upright position, the first and second top surface being in the same plane when the foldable platform being at the horizontal position, a support structure extended from the fixed platform to beneath the foldable platform, and a support rod pivotally attached to a bottom surface of the foldable platform and pivoting between a first and second angle to the foldable platform, the second angle being different from the first angle, when at the second angle, the support rod, the support structure, the fixed platform and the foldable platform forming a triangle holding the foldable platform at the upright position.

A cart includes a chassis and attached wheels; an upper basket attached to the chassis; and a lower basket attached to the chassis. In some embodiments, the cart includes no widthwise push bar in a rear of the cart such that access is unobstructed to the upper and lower baskets from the rear of the cart by a person. In some embodiments, the chassis defines on each lateral side of the cart a pair of vertically spaced handles, each handle surrounding and defining an opening. The handles preferably include handle bars shaped in an oval. On each cart side a curved elongate member extends between and connects the handles, and the curved elongate members represent the rearmost part of the cart. The rear area of the upper basket defines a seat for an infant, and a rear ledge of the lower basket defines a seat for a toddler.

According to an example aspect of the present disclosure, there is provided a novel chassis (100) for a roll container (1000). The chassis (100) features a first arm (121), a second arm (122), and a crossmember (110) for connecting the first arm (121) to the second arm (122) so as to form the chassis (100). The crossmember (110) is formed to be less resistant to mechanical strain than that of the first and second arm (121, 122). The crossmember (110) is such that it can be repeatedly attached to and detached from the first and second arm (121, 122).
