A constructive arrangement in mechanical coupling device applied in vehicles for tow traction is described comprising a square tubular structure (10) arranged horizontally provided in its ends by through-holes (11) receiving the fastening fitting structures (20) next to the vehicle chassis, said square tubular structure (10) showing in the central portion a set of fastening through-holes (12) of a “T”-shaped structure (30) enabling to fit an end cap (40) in a sinuous shape, describing technical improvements by reducing the number of parts, simplifying the constructive process and fast coupling system between the bracket and the end cap, facilitating the use, manufacture, installation, and maintenance of the equipment.

A quick hitch attachment device for coupling the attachment element of a truck bed type system to a quick hitch. The attachment device includes a mounting member tube, a ball hitch assembly and two or more coupling members adapted to mount a mounting member to the quick hitch. The ball hitch assembly includes a stem configured to be slidably received in the tube.

A high visibility retractable safety strap and a method for securing a trailer to a towing vehicle is disclosed. The retractable safety strap is coupled to either the trailer or the towing vehicle. The high visibility nature of the strap increases safety for other motorists by making the presence of the coupling between the trailer and towing vehicle more perceivable. The safety straps also provide redundancy should the main coupling between the trailer and towing vehicle become detached.

A mechanism for clamping a drawbar in a receiver hitch uses a clamp pad to engage two adjacent interior surfaces of the receiver hitch tube. The clamp pad presses outwardly on the receiver hitch tube causing the opposing corner of the drawbar to engage the other sides of the receiver hitch tube. The clamp pad is extended and retracted by a shuttle member disposed inside the drawbar tube. The clamp may be self-aligning with respect to the receiver hitch. An adjustment mechanism is described for translating the shuttle member. An extendable pin mechanism may be actuated by the shuttle assembly. A locking mechanism may be provided to prevent an unauthorized person from releasing the clamp pad and the extendable pin.

A vehicle includes a controller and a frame having a receiver including an electrical connector configured to connect to a trailer having a plurality of chains. The plurality of chains each includes a sensor configured to transmit a position of the chain relative to a winch disposed on the trailer. The controller is configured to, in response to data from the sensors indicating a position of the chains, display via an interface a connection status of the chains.
