Hoisting

Full Text

Early Hoisting The first whims operated by having the horse pull forward to hoist the bucket and back up to lower it. Later units employed a bull gear, pinion, and shaft; this shaft was built into the single drum hoist. The horse circled one direction to hoist, then reversed his position to lower. A hand brake controlled by the top man was an added safety feature.
