ABSTRACT:
An equipment trailer, and more particularly a trailer adapted for hauling large boats and similar objects which has self-lifting framework, is adjustable in lateral width so that it can be used for hauling wide loads, and may be converted to a narrower width for empty transport merely by operation of a hydraulic cylinder that operates through linkages to cause the side rails to be moved in or out relative to a central axis. The unit includes removable cross members and specifically designed removable hangers for such cross members that are attachable to the longitudinal side frame members when the unit is to be used, and which are quickly attached and detached from the side frame members.
