ABSTRACT:
A compensator mechanism for coupling a logging truck and trailer together to allow for relative longitudinal movement between them during turning. A compensator tube is extensibly mounted within a sleeve affixed to the leading end of the trailer reach pole. The forward end of the tube is adapted to be coupled to the truck hitch. A spool shaped roller having a surface which conforms to the compensator tube is mounted on the reach pole in sliding contact with the upper portion of the tube. In operation, as the truck moves along a curved path the roller absorbs lateral thrust loads exerted on the compensator tube and reduces wear between the tube and sleeve.
