摘要

A hitch apparatus is provided for use on a first mobile machine such as a conveyor vehicle to be used with a second mobile machine connected to the first machine. The apparatus includes a track member adapted for mounting at an end of the first machine, this member providing a track having two opposite sides and bent to form a circular arc having a centre of curvature. A hitch unit is mounted for rolling movement on the track and can pivotably connect the end of the first machine to the second machine. The hitch unit includes rollers for engaging both of the opposite sides so that the track is captured between the rollers. The first machine is able to pivot about a substantially vertical axis extending through the center of curvature relative to the second machine and is connected to the second machine for movement therewith.
