The invention is an apparatus and method for lifting objects onto the bed of a pickup truck. The device includes a rack assembly, a swing arm assembly, and at least one hydraulic arm. The invention can be optimized and adapted to fit on a standard pickup truck or a flatbed truck.

A dumper vehicle includes: a frame comprising a front end and a rear end; front and rear wheels mounted to the frame; an operator seat mounted to the frame; and an open topped container for carrying a load therein mounted to the frame between the front and rear wheels, wherein the container is moveable between a transport position for transporting a load and a discharge position for discharging of a load; wherein the container defines an upper extent thereof, and wherein said upper extent of the container decreases in height with respect to a lower extent of the wheels towards the front end of the frame, when the container is in the transport position.

A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a rear wheel assembly, a front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position. At least one of the wheel assemblies is powered by a selectively engageable drive assembly including a motor, transmission, driveshaft, selectively engageable clutch and hub, to drive the rotation of at least one of the wheels.

The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a steerable rear wheel assembly, a steerable front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

A pickup truck can include a bed that is configured to be rotatable. The bed can be defined in part by a first side wall, a second side wall, a front wall, a back wall, and a floor. The bed can include a standard position in which the first and second side walls of the bed can be substantially parallel to a longitudinal direction of the pickup truck. The bed can be selectively rotatable about an axis of rotation into one or more rotated positions. In a rotated position, the first and second side walls can be angled relative to the longitudinal direction. The bed can also be raised in an elevational direction such that a lowermost point of the bed is located above a chassis frame of the pickup truck. A rotatable bed can expand its uses and allow for convenient access to the bed from a desired position.

A tiltable trailer that can assume a high, or road, position, and a low loading position in which the trailer is tilted with respect to the ground. The trailer includes wheels; a chassis mounted on an axle that pivots with respect to the wheels; an actuator for actuating the pivoting of the axle relative to the wheels to vary the position of the chassis with respect to the ground, the actuator including a flexible element secured to the axle and a tensioner attached to the chassis for adjusting tension of the flexible element; and a lock for locking the trailer in the high position, which is separate from the actuator. The lock includes a sliding locking bar, a first end of which is secured to the axle and a second end of which cooperates with a locking mechanism, mounted on the chassis, when the trailer is in the high position.

A lift system for supporting cargo on a vehicle comprising a vehicle frame, the lift system comprises a cargo platform assembly and a displacement system. Operation of a drive system causes axial rotation of at least one drive axle. Axial rotation of at least one drive axle causes at least one drive link assembly to pivot about a drive axle axis. Pivoting of the at least one drive link assembly about the drive axle axis displaces the cargo platform between a stowed configuration and a lowered configuration. First and second distal axes are forward of the drive axle axis when the lift system is in the stowed configuration and rearward of the drive axle axis when the lift system is in the lowered configuration.
