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. [pdf]
