ABSTRACT:
Improved coupling means for connecting a logging truck and a trailer to provide the relative longitudinal movement therebetween to negotiate turns wherein the reachpole of the trailer has a cylindrical sleeve at the forward end thereof and a spring loaded telescopic reach member rotatably mounted therein with its free end connected to the hitch of the truck. These coupling means reduce tight turning and danger of load binding on sharp curves, where most of the accidents happen due to trucks not being able to get around sharp corners. This compensator is easy to maintain, due to fewer moving parts. It remains attached to the trailer, reducing replacement costs of truck, with truck replacement needed twice as often as trailer's. It can also be removed from an old trailer and be re-assembled on a new unit.
