The entire hoisting installation comprising draw-works, drum, and brakes is shown schematically in Figure 2. Factors to be considered when a hoisting system is designed or chosen are: 1. The maximum required hoisting load. 2. The maximum speed at which we can pull the loads. 3. The strength of the line.

Figures 3 & 4 are pictures of a draw-works with an auxiliary electro-dynamic brake. The drive can be either diesel mechanical or diesel electrical. Shafts.

The drum is an essential part of a hoisting system. The size depends on the height of the derrick or mast. Its surface should be grooved so that.

We can divide the drawworks brake systeminto: 1. Main brakes; these are the mechanical brakes on the drum flanges or a hydraulic/mechanical disc brake system. 2. Auxiliary brakes; can be hydrodynamic, electrodynamic, or magnetic particle brakes.

The sheaves in drilling rigs have a large diameter, often 1.5m (60″) or more, to reduce fatigue in wire ropes and increase the endurance of the cable. The diameter depends on the size of the wire rope used. Generally, the sheave diameter is vital because bending the line around the sheave will cause a wear on the line (see Figure 11).
