ABSTRACT:
A hydraulically operated trailer for transporting heavy equipment to a remote operational site, and for lowering the trailer platform and equipment to ground level for operation. A plurality of hydraulic jack assemblies raise or lower the trailer platform. The trailer has a hydraulically operated rear truck dolly which is moved within a track-lined guideway by a push-pull hydraulic ram, so as to be readily moved from under the trailer platform for lowering of the platform. The truck dolly remains pivotally attached to the trailer platform when the same is lowered to ground level.
