Abstract
A pipe section positioning apparatus may be located partially below ground surface level, for example, in a trench to accurately lower and position heavy pipe sections, for example, concrete drain pipe sections, under control of a single operator who has an unobstructed view of the interior of the apparatus. The apparatus includes a body which may be positioned partially beneath ground level, an operator's platform attached to the body above ground level, an elevator within the body, a pipe cradle which is raised and lowered by the elevator and which temporarily holds a pipe section, a horizontally aligned track which is partially positioned beneath the pipe cradle to receive the pipe section and which is horizontally aligned, a ram which moves the pipe section horizontally on the track, and a pipe clamp assembly which clamps the pipe section and which then may be moved, under operator control, horizontally to accurately position and pipe section so that it may be joined with a previously laid pipe section.
