Technical features of mechanical drive drawworks :
  •Bearings all adopt roller ones and shafts are made of premium alloy steel.
  •Drawworks positive gears all adopt roller chain transmission and negative ones adopt gear transmission.
  •Driving chains with high accuracy and high strength are forced lubricated.
  •The drum body is grooved. The low-speed and high-speed ends of drum are equipped with ventilating air tube clutch.
  •The brake drum(or disc) adopts water cycle forced cooling. And the surface is intermediate frequency quenched, which increases its long service life.
  •The main brake adopts belt brake or hydraulic disc brake, while the auxiliary brake adopts configured electromagnetic eddy current brake(water or air cooled).
  Basic parameters of mechanical drive drawworks:
