Abstract

A mine roof support system is disclosed having sets of laterally spaced pairs of elongated support members adapted to be moved into and out of abutting relation with a mine roof. Wheel supported frames extend between and connect adjacent end portions of each pair of support members with adjacent wheel supported frames at the ends of the support members being in spaced tandem relation and connected to each other by connector members. Extensible prop members are connected to and move the wheel supported frames and the elongated support members connected thereto selectively toward and away from the mine roof.
