Mobile Roof Supports Underground


Mobile Roof Supports (MRS) are designed to increase pillar recovery rates in retreat operations, and improve gate road protection in longwall entries. Radio-controlled units normally work in two pairs, with collapsed heights as low as 32” (813mm), and load capacities of 600T or 800T (544 or 727 metric tonnes). Available in extended heights as high as 16’ 8” (5m). When utilizing a set of Fletcher MRS, customers can expect reduction in exposure to: injuries associated with lifting and setting timbers, roof and rib falls, and hazards associated with unexpected caving. Optional tilting lemniscate and roof support assembly accommodate uneven seam conditions.
