mine winder

The firm was one of largest suppliers of coal mine winders.

The towering concrete structures (photo req'd) located at the top of the shafts contained the 3 'Mine Winders' each winder motor rated 3300 horse power.

By 1948 the company had built more than 200 steam and electric winding engines and associated machinery for the home and export markets including a mine winder with a 34 feet diameter drum, 7 feet larger than the ones which made William Oliver move to new premises.
