Abstract
A system for mechanically or hydraulically driving or powering equipment in underground mines off an advance flight of a belt conveyor, in which an assembly of a spaced and drivably connected drive roller and pump and a common base is releasably mountable on wire ropes or other supporting members at opposite sides of the conveyor for selective positioning longitudinally of the conveyor beneath the conveyor belt's advance flight and is vertically adjustable relative to the advance flight for adjusting the driving engagement of the drive roller with that flight for either continuous or intermittent drive of the drive roller and pump while the belt is running.
