Abstract: According to one embodiment, a ramp for loading an animal carcass into a vehicle includes a ramp body having a top surface, a bottom surface, a first end, a second end, a first side, and a second side. The ramp body is curved, and the first end is separated from the second end by a length. The ramp body is designed to be positioned at a sloping angle between a portion of the vehicle and a ground surface so as to allow the animal carcass to be slid upward along the top surface of the ramp body into the vehicle. The ramp further includes a first flange and a second flange coupled to the bottom surface of the ramp body. The first flange is designed to be positioned against the portion of the vehicle, and the second flange is designed to be positioned against the ground surface.

Abstract: Disclosed is an air jack system having at least one air spring with solid plates on each end and an inflatable bag in the center. Each end is capable of attaching to one of multiple devices, and the air spring is operable to push against various items.

Abstract: An air hitch includes an air spring, a mounting base, and a head unit. The air spring is configured with a first and second end, and an inflatable bag configured between the two ends. A pivot unit within the bag allows for up-and-down sliding and pivoting. When the inflatable bag is under pressure, mechanical shocks and other destabilizing forces are substantially dampened.

Abstract: An adjustable trailer hitch for use with automobiles, trucks, tractor-trailers, and other vehicles, and adapters for interfacing the trailer hitch to various trailer-vehicle combinations. The trailer hitch includes a first support member with least one generally vertical track, a second support member with a slide block assembly configured for slidable movement in the track, and a multi-directional dampening system operably connected between the first and second support members. In use, the trailer hitch interfaces the vehicle and the trailer, providing multidirectional dampening that mechanically isolates them from each other.
