ABSTRACT:
A support for the forward end of a log trailer serves to hold the fifth wheel hitch plate of the trailer clear of the ground, thus obviating the need to clean and regrease the plate before each occasion the trailer is hitched to a truck tractor for towing. Such log trailers have articulated booms, which allow them to be folded for transport on the back of a truck tractor. The forward hinge at the hitch plate fails to provide rigidity for the structure when the empty trailer is unhitched, however, thus allowing the hitch plate to fall to the ground unless otherwise supported. The present support comprises a pair of stands having horizontal support members which removably engage mating receptacles affixed to the forward log bunk of the trailer, to which the hitch plate is also affixed. The support members and receptacles preclude rotation of the receptacles, and thus the log bunk and hitch, about the support members, thus keeping the hitch plate and attached structure upright. The telescoping support members allow the space between the stands to be adjusted for different truck tractors, and the height of the horizontal support members is also adjustable for different truck tractors as well. Before an empty trailer is unhitched from its truck tractor, the stands are installed to either side of the rear wheels of the tractor, to support the trailer. The tractor is unhitched and driven clear, with the trailer remaining upright and supported by the stands.
