ABSTRACT:
A vehicular mounted pipe presser includes a pipe-pressing assembly for pressing pipe through a medium wherein the assembly is movably supported by a vehicle and positionable between surfaces which are transverse to the direction of forces employed to press the pipe. The assembly includes a frame having projectable and retractable feet for engaging the transverse surfaces to stabilize the assembly. Movably carried by the frame is a housing for receiving the pipe and a clamping mechanism which floats with the housing for clamping a portion of the pipe. Two clamp jaws of the clamping mechanism are captured within the housing and pressing forces are limited to the housing and the clamp jaws. The projection and retraction of the feet, reciprocable movement of the housing, and clamping of the pipe within the housing are each separately controllable from a stage carried on the housing by hydraulic systems. The hydraulic system for projecting one of the feet is interconnected to the hydraulic system for applying the forces needed to press the pipe through the ground so that an increase in the pressing force results in a corresponding increase in an opposed force being applied by the foot against an engaged surface to continuously balance the two opposing forces.
