The McHitch Uniglide Trailer Coupling has been developed to be an all purpose coupler for all types of caravans and trailers including, off road campers, car trailers, horse trailers, tipping trailers and every type of tow situation out there.
The most important feature of our couplings is the use of a universal joint incorporating roller bearings to handle all of the horizontal/vertical movements, well past 90 degrees horizontally AND vertically (nothing else on the market comes close) with the twisting being handled in the rear body by shock absorbing graphite impregnated polyurethane bushes. The 2 and 3.5 tonne universal joint itself is the same found in all 4wd Landcruisers (industry part no RUJ-2041). The 4.5 and 6 tonne unis are out of a 10 tonne truck (industry part no. K5GB22R). The joint itself is held in place by registers and opposite threaded plugs/end caps which remove any end play and provides enough pressure on the cross to prevent the front section falling down.
The McHitch Uniglide Trailer Coupling goes back to the drawing board and alleviates this problem by separating the point of attachment and the point of wear (the tapered pin is the point of attachment, the universal is the point of articulation) To understand the breakthrough of the McHitch is to understand a fundamental shift in towing technology. Every other type of coupling on the market pivot AND connect to the towing vehicle at the same point. This introduces wear, which introduces play and hammer which creates noise and the potential for the coupling to ‘jump’ off the point of attachment with catastrophic consequences.
Some couplings in common usage have articulation angles as low as 18 - 28 degrees which can cause huge stress and breakage in some instances. McHitch, however, boasts articulation angles in excess of 90 degrees in all directions
