The rotary table is also called a turntable. Most rotary tables are chain driven. These chains resemble very large .
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm). AlternativesMost recently manufactured rigs no longer feature rotary drives. These newer rigs have opted for technology. In top drive, the drill string is turned by mechanisms located in the top drive that is attached t. [pdf]
Rotary drills, on the other hand, make the bit penetrate the bedrock by quasi-statically pushing the bit into the bedrock. It is therefore the down pressure (thrust) on the bit that contributes significantly to. [pdf]
Rotary impact drilling tools have the effect of impact force in drilling, and have higher ROP than traditional PDC and RCB bit. However, the tool has a high requirement for the strength of the bit and needs. [pdf]

This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but. .

The first offshore mobile drilling platform was the Breton Rig 20, first operated in 1949. This rig had evolved from the inland drilling barges which were used to drill in marshes and protected waters in up to 10 feet of water. The Breton Rig 20 was 160 feet by 85 feet, and could work in 20 feet water depth. [pdf]

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 with sprockets and chains provide. .
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. .
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. .
