ABSTRACT:
A tractor-trailer combination is used in a method of constructing a building wherein the trailer has an elongated rectangular walled space (divided longitudinally into three spaces) for hauling walls, construction materials or mold parts to the building site. In the after portion of the trailer and to the rear but near its after wheels, a discharging device is mounted on a support so as to be rotatable about a vertical axis. The discharging device, which is hydraulically controlled, has an arm with three parts, the middle part being the shortest. The outer part which has a coupling member at its end is adapted to lift the walls or mold parts from the trailer and place them at their approximate desired locations on the building site. A mobile auxiliary jack connectable to a hydraulic system of the tractor-trailer combination is used to position the walls or mold parts more accurately. A floor, previously cast, has projections for spacing the mold parts at their bottoms. Stabilizing members pivot outward from the discharging device to engage the ground and provide bracing beyond the trailer's wheels when the discharging device is in use. When not in use, the discharging device rides centrally along the longitudinal axis of the trailer with its outer end on a support, its coupling member above the cab of the tractor, and the stabilizing members are folded adjacent the support for mounting the discharging device. The discharging device has sufficient reach whereby with the rear of the trailer in a single location adjacent the building site, all the walls or mold parts can be positioned by the discharging device substantially in their predetermined locations so that they can be connected to form the building's walls or a mold for casting the walls of the building with minimal further adjustments.
