A vehicle step device includes: a movable step that is provided in a door opening of a vehicle; and a drive controller that drives the movable step so that the movable step operates in deployment and storage directions. The drive controller includes a sidewalk detection unit that detects a sidewalk provided in parallel with a traveling road surface of the vehicle, a separation distance detecting unit that detects a separation distance between a side edge portion of the vehicle in which the movable step is stored and the sidewalk, and a deployment amount setting unit that sets a deployment amount of the movable step extending in a width direction of the traveling road surface from the side edge portion of the vehicle based on the separation distance. The deployment amount setting unit sets a deployment amount of the movable step to be larger as the separation distance increases.

A drop deck trailer is provided with a deck that has the ability to raise and lower to conveniently load and unload goods and materials on the deck. A pneumatic system can raise and lower the deck and also serve as a suspension system for the trailer to dampen the relative movement between a frame and the deck. In addition, some embodiments of the trailer have a deck with a movable carriage that can move along the deck to automatically load a vehicle such as a golf cart. The carriage has rollers that secure the front wheels of a vehicle, and the carriage moves along the decks to pull the vehicle onto the deck. Moreover, various embodiments of a trailer frame can selectively connect to different decks to allow each deck to be specialized for particular goods and materials.

The rack and pinion lift for a tailgate is configured for use with a pickup truck. The rack and pinion lift for a tailgate is a moving platform. The rack and pinion lift for a tailgate is configured for use as a cargo lift. Specifically, the moving platform formed by the rack and pinion lift for a tailgate: a) raises and lowers cargo between the ground and an elevation that is roughly level with the bed of the pickup truck. The rack and pinion lift for a tailgate comprises a port structure, a starboard platform, and a loading platform. The port structure mounts on the tailgate. The starboard structure mounts on the tailgate. The loading platform attaches to the port structure and the starboard structure. The port structure and the starboard structure vertically raise and lower the loading platform.

A mountable elevator system includes one or more horizontal bearing frames and one or more vertical frames, each vertical frame being connected to one of the horizontal bearing frames. One or more step stringers extend between the one or more horizontal bearing frames and the one or more vertical frames. A multi-piece platform includes multiple step pieces mounted on the one or more step stringers. The cabling is configured to extend and retract the multi-piece platform. One or more step support locking structures can be configured to secure a top step piece of the multi-piece platform, wherein the multiple step pieces of the multi-piece platform separate into multiple vertical levels as the multi-piece platform extends. The multi-piece platform is configured to raise and lower relative to an entry door of a vehicle.

A portable lift device that includes a portable lift column assembly having a lift column including a first end, a second end, and a length there between. The second end of the lift column has at least one column attachment system. The lift column assembly further includes a riser assembly coupled to the lift column and movable with respect to the lift column. The riser assembly includes a riser attachment device. The portable lift device also includes a platform assembly movable with the riser assembly and having a platform structure coupled to at least one platform attachment system.
