The drawworks reels in and reels out the drilling line. The drilling line is connected to the traveling block and hook which connect to the drill string. The drill string runs over the crown block and setup like a block and tackle pulley system.

[pdf] The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. It is, therefore, essential. .
In conclusion, Figure 11 shows draw-works brakes’ speed/torque characteristics. 1. Friction brakes may have very high static friction, but with a limitation of dynamic friction. 2. Hydraulic. .
Auxiliary brakes control the descent rate of the traveling block carrying a heavy load. They serve to: 1. Ensure that the load comes down slowly and smoothly. 2. Reduce the wear of. The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake.
