Water Balanced Incline and Drumhouse

The Water Balanced Incline and Drumhouse is located at the top of the incline between levels 5 and 6 of the quarry. The drumhouse features gabled walls that rise to a pitched roof, which currently lacks slates. Inside, there is an internal offset that supports bearing beams for the drum shaft. The drum itself has a diameter of approximately 1.6 meters and is 2.76 meters long between the iron disk flanges, and it is battened with timber. It is equipped with a rim band brake that is operated from an extended lever at the southern end. A twisted steel cable, measuring 25 millimeters in diameter, secures a riveted iron plate water vessel that measures 1.86 meters by 2.16 meters and has a depth ranging from 1.65 to 0.63 meters. This water vessel is mounted on a wooden frame with two axles and curved spoked flanged wheels that engage with top-hat section rails, which are spiked to timber sleepers set flush into the slate-on-edge surface of the incline. Additionally, a water delivery pipe, 78 millimeters in diameter, runs through the drumhouse to discharge water over the water vessel. There is also a ruined lean-to adjacent to the drumhouse.
