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.

The utility model relates to a pluggable two-way tire slip stopper, which is used for solving the problem of sliding when a vehicle is parked. The pluggable two-way tire slip stopper includes two slip stoppers, the back portions of the two slip stoppers are plugged together via a slot in a protrusion manner, the two slip stoppers are identical in structure, and the slip stopper includes the anti-slip portion of a front end and the plug portion of a rear end, the anti-slip portion is integrally formed with the plug portion, the plug portion is in the shape of a square, the plug portion is a triangular column shape with an obliquely upward surface, and the anti-slip portion is provided with a plurality of anti-slip belts, and the anti-slip belt is disposed at a certain distance, the upper surface of the anti-slip belt is inclined, and the anti-slip belt is provided thereon with a plurality of anti-slip protruding strips. The two slip stoppers of the utility model can be combined and plugged together, can be used in combination, and uses a two-wheeled vehicle to prevent slippage, whose effect is very good. The utility model has the advantages of scientific design, convenient use and good use value. The utility model is light and durable, convenient to carry, safe and convenient.

A tipping prevention unit that prevents tipping of an image forming apparatus includes shafts holding a wheel of the image forming apparatus, a shaft that abuts the image forming apparatus at a position higher than the shafts, and a shaft that contacts a floor surface on which the image forming apparatus is placed at a position further protruding to the outside of the image forming apparatus than the wheel of the image forming apparatus.

The wheel chock handling unit includes a base, an articulated cantilever arm assembly, a main spring assembly and a force-compensation mechanism. The arm assembly has a first end pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position. It also has a second end receiving a wheel chock. The main spring assembly extends between the arm assembly and the base. The force-compensation mechanism includes a lever pivotally mounted to the base for angular displacement in a plane that is substantially parallel to that of the arm assembly.

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.

A wheel chock system comprising at least one wheel chock for supporting a vehicle, detecting a load imparted by the vehicle, and displaying information indicative of the load imparted by the vehicle is described herein. In some embodiments, the wheel chock detects a load imparted by a vehicle with a load sensor and displays the load. The wheel chock may be in communication with other wheel chocks supporting the vehicle. The wheel chocks may display the loads detected by all wheel chocks and may determine and display a load distribution across all wheel chocks.
