Abstract
A multidirectional runner assembly for positioning a carrier pipe within a surrounding casing pipe. Each multidirectional runner assembly has at least one ball transfer assembly at least partially protruding from the runner assembly, in order to contact an inner surface of a surrounding casing pipe. The ball transfer assemblies reduce static and/or kinetic friction forces during installation of a carrier pipe within the central bore of a casing pipe, permit multidirectional orientation of the runners within the casing pipe, and provide greater load support.
