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.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end of the chassis, a second actuator coupled to the first end of the chassis, a third actuator coupled to the opposing second end of the chassis, a fourth actuator coupled to the opposing second end of the chassis, and a control system. The control system is configured to fluidly couple at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator, and fluidly decouple and actively control the at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator.

A trailer has a frame for lifting, transporting and lowering loads. The trailer is towed by a suitable towing device and includes a lifting device for lifting and lowering the load. Means compatible with the type and weight of the load are coupled with the lifting device. The means are forks in the case of stationary loads such as boxes, or a plane surface in the case of a movable loads. The trailer moves in a stable manner because the lifting device is stably secured on a part of the front side of the trailer and wheels are arranged on either side of the trailer. The trailer has a crossbeam on the rear side, which supports part of the weight of the load once it has been lifted and prepared for travel, and one or more support beams across the width inside the trailer.

A shelving system comprising at least one guide track and at least one shelf assembly, the guide track and shelf assembly comprising mutually interacting means to provide for the shelf assembly being carried by the guide track while carrying a load. The guide track provides for a displacement of the shelf assembly along the guide track while carrying the shelf assembly, and allow releasably fixing the shelf assembly to a plurality of different positions along the at least one guide track. The shelf assembly comprises at least two displacement elements for displacing the shelf assembly along the guide track, and the displacement is effectuated by an actuator controlling a motion of the displacement elements. Following release from a first position along the at least one guide track and displacement to a second position along the guide track, the shelf assembly is releasably fixed at the second position.

A vehicle includes a frame and a debris hopper including a door disposed along a side of the vehicle. The vehicle also includes front and rear lift assemblies supporting the debris hopper on the frame and configured to lift and tilt the debris hopper relative to the frame. Each lift assembly includes a transverse support mounted across the frame. A lift arm including a first end and an opposite second end, with the first end of the lift arm pivotably coupled to one end of the transverse support. A leg extending below the debris hopper and disposed proximate the door, with the second end of the lift arm pivotably coupled to one end of the leg opposite of the debris hopper. A first fluid actuator extending between the transverse support and the lift arm, and a second fluid actuator extending between the lift arm and the leg.

A lift system for supporting cargo on a vehicle comprising a vehicle frame, the lift system comprising a cargo platform assembly and a displacement system. The displacement system comprises a lift frame assembly, a drive system, at least one drive link assembly, and at least one stabilizer link assembly. Operation of the drive system causes axial rotation of the at least one drive axle. Axial rotation of the at least one drive axle causes the at least one drive link assembly to pivot about the drive axle axis. Pivoting of the at least one drive link assembly the drive axle axis displaces the cargo platform between a stowed configuration and a lowered configuration. Displacement of the cargo platform between the stowed configuration and the lowered configuration causes rotation of the at least one stabilizer link assembly.
