Abstract
A gooseneck hitch is held in coupled relation with a trailer platform by a pivoted link which is adapted to be rocked rearwardly by hydraulic actuators to raise the forward end of the platform to a transport position and rocked forwardly to lower the forward end of the platform to the ground and permit removal of the gooseneck from the platform. During towing of the trailer with the platform in a normal transport position, the actuators are hydraulically unloaded and the link is held against forward rocking by a pair of compression cams. The cams are manually released from the link during removal of the gooseneck but are automatically re-engaged with the link during re-installation of the gooseneck so as to relieve the trailer operator of the re-engagement task. The cams may be selectively adjusted to change the transport height of the forward end of the platform and/or to compensate for variations in the height of the fifth wheel coupler of the towing vehicle.
