No.2 Colliery Wheel, Woodhorn Museum
This was constructed between 1899 and 1901 by Head, Wrightsons & Co. of Stockton-on-Tees. The Heapstead held the winding gear to raise and lower cages along the upcast shaft, to a depth of 887 feet. The heapstead was tightly controlled with airlocks to help the effectiveness of the fans to expel the air from underground.
