This cable/hoist drum was manufactured for a cable/ hoist that is used by various heavy industries. Composed of carburized 8620 forged steel, and 1045 flame hardened steel, it measured 175" in length with an outside diameter of 36". The drum assembly was comprised of brake sheels, cable sheaves, sheaves pins, and axles and was precision CNC machined in our facility. Heat treating and tempering where applied using carburizing which provided a case depth up to 1/8" per side at 60-62 Rc. Flame hardening provided case depths of .90" at 55-58 Rc, and quenching produced tempering of 60 Rc. Dimensional testing was performed throughout to verify that we maintained the required tolerances of ±0.001".
