An automatic wheel chock device includes a motion unit and a mounting bracket for engaging a vehicle or trailer. The motion unit is connected to a swing arm having a wheel chock located along the distal end thereof. The motion unit transitions the swing arm between a retracted and extended position to secure the wheel chock against the vehicle tire.

A device for combining with a vehicle to prevent movement of a wheel. Multiple links are pivotably connected in series and in a loop. In the loop configuration, two spans of the loop may be placed at an angle to one another between a few degrees and 30 to 60 degrees. A third span may connect the first two spans to form a triangle or another shape that may be placed with a first span resting on the surface the wheel is resting on and the second span in contact with the wheel. A third span may connect the other spans. A pin may be removed from the links and disposed in an un-looped configuration for use under a wheel on a low traction surface, such as snow or mud. The links may be rolled up for storage or attached to a vehicle and used as a mud flap.

A light, hand-held, generally block U-shaped rubberized stopper for manually-operated, wheeled hand trucks or pallet trucks. The stopper is placed on the floor surface and is guided, by the operator's hand or foot, toward the front pivot wheel or wheels of the pallet truck, once the front wheels of the pallet truck have been rotated 90 degrees in either direction. The wheels fit into the open end of the block U-shaped stopper, and the stopper is pushed in so that the prongs and the closed bracket end of the stopper enclose the front wheels of the pallet truck, in order to prevent movement and “park” the pallet truck in place. The distance between the prongs, and the stiffness or resistance of the prongs, are designed to grip the wheels of the pallet truck when in use and lock them in place, preventing movement. Additionally, each prong of the stopper has one or more raised ramp or wedge features on its top face that act to cradle the pivot wheels of the pallet truck when in their locked position, further restraining their movement. The stopper has a tab or handle that allows it to be hung from the handle of the hand truck, or on a wall or in a cabinet, when not in use. The stopper is constructed of light, durable, portable, PVC-grade moulded rubber, with a corrugated or sandblasted underside surface to further prevent movement of the stopper when in use. The stopper's construction meets all environmental and safety requirements, and is structurally able to withstand repeated use under a wide range of environmental conditions.

A convex wheel chock includes a contact surface generally facing a vehicle tire, a support element connected to the contact surface to transfer a tire load from the contact surface, and a base portion coupled to the support element to provide structural support to the wheel chock and transfer the tire load to a ground surface. The contact surface includes a convex surface to be engaged by the tire, extending generally upwards from the base portion to the support element. The convex wheel chock may further include a concave extension surface joined to an upper end of the convex surface.

Described herein is a vehicle cone placer and chock assembly. The vehicle cone placer is equipped with collapsible traffic cones, a motorized linear actuator, and may have LED safety lights. The vehicle cone placer is telescopic, remote controlled, and mountable to a vehicle. The vehicle cone placer and chock assembly includes at least two chock systems and adjustable brackets hydraulically operated and with at least one motorized assembly. The vehicle cone placer and chock assembly is remotely operated and self-contained as components of the vehicle.

A compression wheel chock system is disclosed. The system is comprised of two, triangular-shaped devices having longitudinal channels and a lanyard. An object of the apparatus is to enhance wheel chocking by preventing a wheel from moving both fore and aft while chocked. During installation, the lanyard is fed through a channel in each chock and is drawn tight by the user. As the lanyard is tightened it compresses the chocks around the wheel while at the same time compressing the channels and securing the lanyard therein.
