ABSTRACT:
Essentially L-shaped housing modules used to construct a multi-level apartment building are transported to an erection site on a flat bed trailer drawn by a winch-equipped towing truck. An identical truck is used to tow a construction crane tower to the site on a trailer vehicle which is later utilized as a counterweight for a simplified fixed radius non-rotating crane based on one of the trucks and erected by use of the second truck. Twin opposing cranes are employed to lift and manipulate housing modules at the site. A special lifting truss with hinged transverse extensions is employed in conjunction with the twin cranes and has means for coupling to each housing module so as to add to the rigidity of the latter. Worker platforms on the crane towers have manual winch means for making fine adjustments in the attitude of each module so that the module can be correctly set into place on underlying modules or on a prepared foundation.
