A universal chassis frame is disclosed having a ladder-frame construction that is configurable to position the rear axle(s) at variable set of preset distances from the back of the cab of the vehicle to provide for customized rail/bed lengths over a range of medium/heavy classes of electric trucks. In various embodiments, the chassis frame includes a central frame having a pair of main frame rails configured to support at least two battery modules substantially within an intra-frame space defined between the pair of main frame rails. A front subframe is configured to support a cab, the front portion including a pair of upper frame members mounted above the corresponding pair of the main frame rails, and a front axle unit mounted under the front subframe. A rear subframe is configured to support at least one rear axle unit mounted under the rear subframe and any of a set of multiple configurable rear payload units via a common connection interface affixable to the main frame rails such that the location of the rear subframe with respect to the main frame is longitudinally variable at different sets of predetermined distances from the back of the cab.

A foldable vehicle may include a chassis comprising a static support a dynamic chassis frame that includes at least two substantially opposite frame parts and a folding mechanism for decreasing or increasing a distance between the at least two substantially opposite frame parts across a lateral axis of the vehicle between a folded state and an unfolded state; and a controller to control the folding mechanism.

The present application discloses a pallet truck backrest assembly for handling half-size pallets. A first half-size pallet support is pivotally coupled to a backrest of the backrest assembly at a first height and a second half-size pallet support is pivotally coupled to the backrest at a second height with the second height being less than the first height. The half-size pallet supports pivot between first positions against the backrest and second positions extending over the forks of the pallet truck to accommodate half-size pallets.

The present application discloses a wheel beam type axleless vehicle frame that comprises five sections in sequence from front to back, including a front hanging rack, a front wheel carrier, an intermediate coupling rack, a rear wheel carrier, and a rear hanging rack. Every two adjacent sections amongst the five sections are manufactured and connected in a unified and standardized integrated mode; a modular combination structure is used; and the five sections, which are independent respectively, may be assembled and adjusted according to requirements, and have sufficient strength and stiffness as well as completely independent interchangeability. The vehicle frame has the advantages that match with the needs of an electric vehicle, and thus may be used as the optimum configuration frame for the electric vehicle; and the vehicle frame may be improved according to requirements to be applicable to various fuel and hybrid electric passenger vehicles and commercial vehicles.
