Water well drilling rig AC circuit diagram

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. . 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,. . 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). . 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 Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. [pdf]

Drilling rig traveling block

This block is a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the sheaves on the crown and through the sheaves in the traveling block. This provides a significant mechanical advantage to the drill line, enabling it to lift heavy loads of pipe and casing. The. . The size of the groove should be the same as the diameter of the drilling line to deliver the proper support. A tiny pulley groove could cause high friction. Furthermore, it can cause. . Periodic inspections: The Rig Traveling Block, as with all Hoisting equipment, must be inspected according to the manufacturer’s recommendations and API RP 8B or related ISO (International. [pdf]
