A reversible ramp adapted for use with a trailer or truck that has an elongate rigid structure with a hook on one end for a trailer and a lip on the opposite end for a truck. The lip has a curved portion that protrudes beyond the elongate rigid structure and terminates at an edge with a lip plane extending from the edge to a corner of the elongate rigid structure. The hook terminates at an edge with a hook plane extending from the edge to a corner on the other end of the elongate rigid structure. The hook plane is at a larger angle with respect to the elongate rigid structure compared to the lip plane. In use, the hook plane aligns with the ground when the lip end is on the truck. Likewise, the lip plane aligns with the ground when the hook end is on a trailer.

A ramp deployment system for deploying and securing first and second ramps to the entrance of a container-type vehicle using a ratchet strap arrangement. The ratchet strap arrangement includes first and second ratchet strap devices each having a tightening strap coupled to a respective hook and collar mechanism that includes a closable hook operable to engage a collar to form a loop portion by the tightening strap around the undercarriage of the container-type vehicle. A ratchet mechanism is operatively coupled to the tightening strap for tightening or loosening the tightening strap relative to the first and second ramps when the ratchet strap mechanism is actuated. The ratchet mechanism is also engaged to a fixed length strap having a hook portion configured to engage the cross rungs of the first and second ramps and secure the ratchet strap arrangement securely between container-type vehicle and the first and second ramps. In some embodiments, a pair of connecting bars may be coupled between the first and second ramps to provide structural reinforcement between the first and second ramps.

A ramp system is disclosed which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.

A height adjustable loading ramp installed at a tail of a car, for loading or unloading goods, includes: a slope plane and a supporter. The two ends of the slope plane are respectively supported on the ground and the supporter. The supporter includes: two supporting legs adjustable in length, a beam horizontally provided between lower portions of the two supporting legs, wheels for making the loading ramp move conveniently, and a scissor jack for adjusting the height. The scissor jack includes: four scissor jack arms equal in length, and an adjusting-locking device for adjusting and locking the height of the height adjustable loading ramp. In addition, the supporting leg comprises an auxiliary fixing unit for fixing the relative position between the upper and the lower supporting legs and providing an extra security protection, in such a manner that the height of the height adjustable loading ramp is locked.

A pet ramp system has a central pier and at least one ramp with an axle that is received in an axle receiver disposed near the top of the pier. The axle is disposed inwardly, in both a fore and aft direction and in a transverse direction, from a base perimeter of the pier. The pier's axle receiver(s) permit installation of the ramp axle when the ramp is in a vertical orientation, but the receiver(s) will not permit separation of the ramp from the pier when in use.

A portable slope comprising at least a plate member and a first reinforcing part, and configured in a manner such that the first reinforcing part extends in the longitudinal direction of the slope, a hollow part is formed between the plate member and the first reinforcing part, the shape of the cross-section perpendicular to the longitudinal direction of the first reinforcing part is quadrangular, and the like. Provided is a portable slope to be used to bridge a difference in step produced between buildings and train car bodies, the portable slope being lightweight and exhibiting excellent load bearing characteristics and durability, making it possible for a wheelchair-user to safely travel on the slope by the positioning of derailment prevention walls on both lateral surfaces of the slope, and further exhibiting excellent portability as a result of the slope itself being lightweight.
