A method and a system including a catcher tire abutment device is described for restraining road vehicles transported on a support surface of a transport vehicle. Primary wheel restraining devices are secured to the support surface on outward sides of pairs of wheels of each road vehicle adjacent the thread surface of the wheels. A catcher tire abutment device is also secured to the support surface an approximate predetermined distance spaced adjacent the thread face on inward sides of front and rear pairs of wheels of the vehicle. When the road vehicles are subjected to an impact force, from either a front or rear direction, kinetic energy from the impacted vehicle is absorbed and dissipated softly in a sequential manner by (a) contact of the tires of one of the front and rear pairs of wheels against an arresting surface of the primary wheel restraining devices and (b) by the tires of the other pair of wheels contacting the arresting surface of the catcher tire abutment devices.

A wheel chock (10) configured for placement under a resting rubber tired wheel (W), such as a wheel found on a powered vehicle, to maintain the wheel (W) at rest is disclosed. The wheel chock (10) broadly includes a body (12) that defines an internal chamber (14) in communication with an open face (16) presented by the body (12). The body (12) presents a prism-like configuration having a generally triangular shape and includes a pair of oppositely spaced sidewalls (18, 20), a rear wall (22) extending between and adjoining the sidewalls (18,20), and a wheel-supporting surface (24) extending between and thereby enclosing the walls (18,20,22). The wheel-supporting surface (24) presents a low profile, arcuate leading tire-engaging edge (34). The arcuate leading edge (34) substantially complements the contour of the tire and enables the chock (10) to be easily placed under the wheel (W) in an optimal operating position i.e., in close adjacent alignment with the wheel (W) so that at least a portion of the majority of the circumferentially extending treads of the rubber tire of the wheel (W) engage at least a portion of the chock (10) with a minimal exertion of force and effort by the user. The internal chamber (14) in communication with the open face (16) enables the body (12) of the chock (10) to be stackably nested within another similarly configured wheel chock to provide a compact, space-efficient storage of the chocks that facilitates ready portability for transportation of a pair or more of the chocks in the vehicle.

A supplemental restraint for a primary vehicle restraint system for an auto-rack railroad car which reduces or eliminates movement of the vehicle in the auto-rack railroad car. The supplemental restraint is adapted to be positioned on a grating between the tire of the vehicle and the primary restraint. One embodiment of the supplemental restraint includes a body and an expander connected to the body. After the primary restraint is locked in place on the grating, the expander of the supplemental restraint is expanded. The expansion causes a more secure engagement between the tire and the primary restraint. This causes a high level of engagement between the tire and the primary restraint system indirectly through the supplemental restraint. The supplemental restraint also maintains a higher contact area on the tire regardless of the position of the primary restraint.

A trailer is described, defining a floor extending from a first end, and comprising at least one first displaceable platform onto which goods can be loaded from the first end of the trailer. The first platform is supported such that it can be elevated when loaded and advanced away from the first end of the trailer when loaded. The first platform is preferably rolled forwards onto support tracks provided on the sidewalls of the trailer. The trailer may also include a load-carrying well with its own moveable cargo platform or platforms, and the first platform is loaded and moved up and over the well, thereby increasing the capacity of the trailer. Corresponding cargo-carrying vehicles, and loading methods are described and claimed.

A wheel chock for restraining movement of a vehicle tire on a supporting grating during transit includes a base, a grate lock mechanism for locking the base to the grating, and a ramp on the base for engagement with a circumference of a vehicle tire. A strap connected with the base is extensible around the vehicle tire to help restrain movement of the tire on the grating. The chock includes a retractor for retracting the strap and for taking up slack that forms in the strap during transit.

A wheel chock mounting plate assembly that can be easily attached to and removed from the load surface of a trailer or other transporting vehicle. The wheel chock mounting plate assembly attaches to a logistic track, standard in the field of cargo control systems, that is fixed to the load surface. The wheel chock mounting plate is precisely drilled and machined to receive a wheel chock. The mounting plate assembly has a fitting adapted to engage the logistic track attached with a logistic strap to the rear end of the mounting plate. At least one longitudinally slideable key is adapted to extend below the mounting plate to fit in a transverse opening of the logistic track to prevent the mounting plate from moving in a direction transverse to the length of the logistic track. The front of the mounting plate has a fitting adapted to engage the logistic track and secure the mounting plate assembly in the longitudinal direction of the logistic track.

A configurable wheel lock comprising a rigid chock and an adjustable fork pivoted to the chock that engages a wheel seated within a cradle. The fork projecting from the control portion mounts a pair of separate arms pivoted to opposite ends of an axle that is slidably captivated within guide slots in the chock sides. Projecting arm stubs are inserted within the wheel to be captivated for locking. The fork arms rotate in a first plane that is coplanar with both arms and the axle, and they may be rotated about the axle. These combined rotational features enhance the positional abilities of the arms, and the dexterity of the wheel lock. Rigid locking-links pivoted to at least one of the arms are extended to the opposite arm to lock it in a selected locking position about the wheel.

A wheel clamp includes a clamp body, a movable rod pivotally connected to the clamp body, a connecting rod fitted on the movable rod, and a rotating unit disposed in a lock core seat of the clamp body. The connecting rod has a threaded section for connecting with a screw. The rotating unit has a rotating rod to be inserted into an accommodating trough of the screw. A first engaging member is secured to the accommodating trough of the screw. A second engaging member is secured to the rotating rod of the rotating unit. The second engaging member has a second engaging block to mesh with and drive a first engaging block of the first engaging member so the connecting rod is able to be moved relative to the screw.

An apparatus for supporting a motorcycle in an upright position. The apparatus includes a base and a wheel stop coupled thereto. A cradle is pivotably coupled to the base and includes a pair of clamp members slidably coupled thereto. The pair of clamp members are biased away from each other. In other embodiments, a chock apparatus and a method of holding a motorcycle in an upright, stable position using a chock apparatus are provided.
