Abstract
A hitch assembly for connecting a front end 21 of a low-loader trailer to a tow vehicle 10 is disclosed. The hitch assembly includes: a first mount 22 located at the front end 21 of the trailer; a second mount 25 longitudinally spaced towards the rear end of the trailer from the first mount 21; a gooseneck frame 40 having a front end and a rear end, the front end connectable to the tow vehicle 10; a latch connectable 50 to the front end 21 of the trailer by engagement with the first and second mounts 22 and 25, the latch 50 pivotally connected to the rear end of the gooseneck frame 40; and a means for rotating the latch 50 with respect to the gooseneck frame 40. The assembly is such that in use, the front end of the trailer 21 is liftable by the action of a force couple imparted entirely through the latch 50 to the first and second mounts 22 and 25. The pivotal connection between the latch and the gooseneck frame is positioned on the gooseneck such that, in use, rotation of the latch 50 to lift the front end 21 of the trailer, moves the trailer forwards with respect to the rear end of the gooseneck.
