ABSTRACT:
Trailers for use in hauling logs and adapted for use in tandem have fore and aft bunks each of which has a pair of horizontal members that are connected by a central pivot to the trailer and have vertical stakes at their outer ends. An air operated piston-cylinder unit is provided for each bunk with its rod connected by links to the members to enable them to be pivoted between a first position in which transversely aligned stakes are spaced apart a minimum distance to provide a minimum trailer width and a load-receiving position in which the distance between corresponding stakes is increased to establish a maximum trailer width.
