A typical drawing showing a Robey undertype semi-portable engine coupled to winding drums. The 1881 quarry plans show a plan view of this sort of arrangement, with two drums and a crank. The 1913 inventory for the Old Robey reads as follows (apart from electrics): 1 20 NHP Undertype Robey engine & Loco Boiler 2 drums x 6 ft dia Ropes 7/8" x 485 yards and 350 yards
