Gin

nounStandard termMining

A historic vertical hoisting drum used to raise ore, coal, or workers from a shaft.

This traditional winding engine consisted of a large wooden drum mounted vertically and turned by a horse walking in a circle. Ropes wound around the drum passed over pulleys at the shaft collar to lower and raise buckets or corves. It was the standard method for hoisting in shallow mines before the widespread adoption of steam power.

Heard on the job

The old shaft collar still has the circular track worn into the bedrock where the horse turned the gin.
