In all oil field hoists or drawworks for heavy duty drilling below 5,000 feet, it is desirable to provide water cooled brake flanges for the hoisting unit to prevent overheating of the brakes under heavy loads which cause a large amount of wear on the brake flanges and lining, thus requiring frequent replacement of the parts. The most convenient arrangement for cooling the brake flanges is to introduce water through drilled passages in the end of the drum shaft, and circulate it through jackets on the inner surfaces of the brake flanges. Air clutches are commonly used on the drum shaft of modern hoists or drawworks which necessitates the introduction of compressed air to the drum shaft for actuating the clutches.
