A material transport cart includes a cart body, a material support body coupled to the cart body, a wheel coupled to the cart body, a motor operable to drive the wheel, and a powered lift assembly. The powered lift assembly is coupled to the cart body and to the material support body. The powered lift assembly is operable to lift the material support body relative to the cart body. A removable battery is electrically coupled to and operable to supply power to both the motor and the powered lift assembly

A hand truck with main wheels and a toe plate also includes a handle assembly that is mounted to the frame of the hand truck so that the handle assembly is able to rotate and slide relative to the truck frame. The hand truck may be arranged in a first upright dolly position in which the handle assembly is generally aligned with the truck frame and a second cart position in which the truck frame is generally horizontal and the handle assembly is extended and rotated so that it is upright and normal relative to the truck frame. A latch assembly mounted to the truck frame is able to releasably receive and secure the handle assembly in the first upright dolly position.

A flatbed truck with a foldable caster unit, comprising a load-bearing plate, a load-bearing support frame and a caster unit, and further comprising a caster unit rotation driving device. The caster unit rotation driving device comprises an operating handle, a connecting rod, a front linkage mechanism and a rear linkage mechanism, wherein the operating handle is pivotally connected with the load-bearing plate and is rotatable around a pivot axis of the operating handle. The operating handle is capable of linking with the front linkage mechanism and the rear linkage mechanism via the connecting rod to respectively drive the front caster unit and the rear caster unit to be rotated from the folded storage position to the unfolded rolling position, when the operating handle is rotated from a first position to a second position.

A mobile welding cart designed to incorporate and integrate components to lift the welding unit, and to provide power for accessory components and tools, is provided. The cart comprises a base frame, supported by four wheels, connected to a lifting platform by way of a scissor lift mechanism. The lifting platform is operable between an expanded position and a retracted position. A storage compartment is located on the lifting platform and a welder is located on top of the storage compartment. The cart also includes a power box connected directly to the rear of the storage compartment that is designed to receive power from a single extension cord connected to the input power of choice. This power box may provide power to all required components and may be equipped with components to convert the power emanating from a power supply in the power box.

A collapsible maintenance cart includes a lower structure and an upper structure that are movable between a stowed configuration and a working configuration. In the working configuration, the lower structure and the upper structure together define an interior workspace, and the upper structure is movable relative to the lower structure between a raised position and a lowered position. In the stowed configuration, a height of the collapsible maintenance cart in the stowed configuration is less than a height of the collapsible maintenance cart in the lowered position of the working configuration.
