Abstract This invention relates to prefabricated elements of relatively large dimensions, of reinforced or like molded concrete, incorporating all the necessary equipments, appliances and piping and wiring systems, these elements being adapted to be easily connected at the building site to other similar elements and to be constructed at a manufacturing plant and transported by road within the limits of exceptional transport dimensional tolerances. The invention also includes a trailer adapted to transport these elements and comprising to this end a wheelmounted platform responsive to hydraulic jacks for steering the trailer axles, longitudinal beams of telescopic type and provided with means for locking them in the selected longitudinal dimension, whereby the trailer may be returned to the plant under no-load conditions without exceeding the prescribed transverse dimensions of ordinary transport vehicles.
A trailer comprising; a chassis, an element handling platform on the chassis, steerable rear wheels on half-axles controlled by transverse hydraulic cylinder and piston actuators mounted thereto, hydraulic jacks vertically mounted on the half-axles for supporting said platform and independently controlled for varying the cant of the platform relative to the ground, a gooseneck mounted to the front of the trailer, an arm pivotally attached at one end to the gooseneck, a pintle mounted to the arm at the other end and a hydraulic cylinder and piston unit pivotally attached to the gooseneck and arm for vertically adjusting the orientation of the platform in cooperation with rear half-axle mounted jacks.

Claim 3
Dependent Claim
51 words
Trailer as set forth in claim 1, wherein said platform comprises a plurality of transversely movable cross-members adapted to project beyond the normal width of said platform and to support the element to be transported, said cross-members being adapted to be actuated by means of transverse hydraulic cylinder and piston units.
Claim 4
Dependent Claim
38 words
Trailer as set forth in claim 1, wherein said chassis is longitudinally extensible in that it comprises a pair of telescopic longitudinal members adapted to be locked in the selected position by means of pegs accessible from outside.
