WOODHORN MUSEUM COLLIERY WHEELS RECEIVE INSPECTION

About the Job…

The colliery wheel (Heapstead) 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.


Issues…

Warren Access’s customer BGP Tyneside requested their free site survey service, as they were unsure of the ground conditions and outreach required to be able to complete a full structural inspection. An access platform was required due to a metal fence has been erected at the base of the Heapstead tower protecting the structure however this also prevented a machine from setting up directly next to it.


Solution…

The tower leading up to the wheel was thought to be unsafe for pedestrian access due to aged, worn walkways and access ladders so a team was put together to inspect the walkways and structural integrity. Several teams from different companies with their own particular expertise were involved in this project to ensure every aspect of the colliery wheel fixtures and walkways were inspected. Together with Warren Access’ operator and the 33m Ruthmann truck mounted platform, the job was a complete success!
