An improved coupler for a tongue on a towed vehicle that attaches to a tow hook mounted on a towing vehicle to either pull the towed vehicle over a road or to pull the towed vehicle located on an elevated surface. The coupler includes an elongated tongue tube attached to the end of the tongue attached to the towed vehicle. Upper and lower rings are axially aligned and mounted or attached to the front surface of the tongue tube. The rings are spaced apart on the tongue tube to allow the towing vehicle pull or push the towed vehicle over the same roadway or over an elevated surface. Brackets are used between the tongue tube and the trailer tongue to prevent compression, collapse, and prevent fore to aft or aft to fore movements. An adjustable jack is attached to the side of the tongue tube. An optional lid is provided over the top opening of the tongue tube that covers a storage compartment inside the tongue tube. An optional chock holder plate and a pair of compatible chocks may be placed inside the storage compartment.

A vehicle wheel torque brace for inhibiting rotation of a vehicle wheel includes a brace body including a relatively thick stopper portion and a relatively thin wedge portion that is stepped down in thickness relative to the wedge portion. The wedge portion decreases in thickness from one side of the brace body to an opposite side of the brace body. A contact pad is carried by the wedge portion. The contact pad and wedge portion are shaped and sized to be wedged between a tire of the vehicle wheel and a strut assembly to inhibit rotation of the vehicle wheel.

The wheel chock (100) is designed to prevent a vehicle (104) from moving in an unauthorized or accidental manner. The wheel chock (100) includes a longitudinal extension (200) to further improve resistance to rollover and tipping when the wheel (102) is pressed forcefully against the wheel chock (100). The extension (200) includes a protruding portion (210) that can extend over a relatively long distance along the tire sidewall (126) and allows the wheel chock (100) to create a latching engagement between a tooth (160) and a blocking element (112) on the base plate (110) beyond the front end of its main body (150).

A wheel chock includes a base member defining a generally triangular prism shape having two triangular side and three faces joining the edges of the sides. A gripping surface defined on at least one of the faces. A handle, for being grasped by a user, disposed on either one of the sides or one of the faces adjacent the face defining the gripping surface. A magnet disposed along one of the sides of the base member, such that at least a portion of the magnet is recessed within the base member. The magnet allows the chock to have a stowed position in which the device is magnetically coupled with a ferrous surface of an equipment, and an in use position in which the chock is positioned near a wheel.

A folding wheel chock has a stop ramp having a front face shaped to interface with a vehicle wheel, extending from a first support base to a first vertex, and a support wall extending from a second support base to a second vertex. The stop ramp and the support wall are hinged by a pivot pin at the respective first and second vertexes to rotate between an in-use or working configuration and a non-use or resting configuration. The folding wheel chock has a tip acting as a portion of the first interface with the vehicle wheel, the tip associated with the stop ramp and movable from an extracted or working configuration, in which it protrudes towards an associable wheel as an extension of the stop ramp, to a retracted or resting configuration in which it is arranged at least partially folded or aligned on the stop ramp and/or support wall.

A wheel locking device comprising a number of interlocking components that are adapted to receive a wheel (or a wheeled apparatus), and said components can be adjusted to accommodate a variety of wheels of different diameters. The wheel locking device further comprises a rotatable and adjustable bar that is utilized to secure the wheel in place. In further embodiments, the device comprises a lock receiving bore which is adapted to receive a lock.

A wheel chock has a body with a shell and filled core construction capable of supporting high chocking loads while being relatively lightweight and portable. The chock includes walls sized and shaped to support large-diameter wheels such as wheels of large haul vehicles and mining trucks. The chock can be sized proportional to the radius of the wheel to be retained or based on the radius of curvature of a wall configured to primarily support the outer surface of the wheel. The chock can have a cut off or flattened toe or front surface that reduces weight and helps to ensure that the entire chock is load-bearing when in a chocking position. The chock can also have a flattened top surface to support the outer surface of a tire that deforms around the chock while it is being retained by the chock.
