Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can pull is dependent on the height of the derrick. .
The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. .
The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. .
The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. .
Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing).
