• a fixed set of pulleys at the top of the derrick of a drill rig over which the drilling line is threaded.

  Crown block
• The pulleys are assisted by travelling blocks that together are capable of hoisting heavy loads with the use of 3/4 inch to 1 1/2 inch diameter drilling line.

  Crown block
• Crown blocks help lift heavy loads even in rough weather conditions offshore when the drill vessel experiences heaving. Crown blocks are part of drill rigs that are used for oil and gas drilling operations.
• The fixed set of pulleys (called sheaves) located at the top of the derrick or mast, over which the drilling line is threaded

  Crown block
• The drawworks is a mechanism commonly known as a hoist. The main purpose of the drawworks is to lift the drill string out of and to lower it back into the borehole.
• Cathead is a spool shaped attachment on a winch, around which rope is wound. This can be used for hoisting operations on the rig floor.
• The set of sheaves that move up and down in the derrick. The wire rope threaded through them is threaded or “reeved“ back to the stationary crown blocks located on the top of derrick.

  Traveling block
• A traveling block is the freely moving section of a block and tackle that contains a set of pulleys or sheaves through which the drill line (wire rope) is threaded or reeved and is opposite (and under) the crown block (the stationary section).
• Components of a traveling block: Sheaves, Hook, Frame
• The primary function of the traveling block is to provide the mechanical advantage necessary to lift and lower the drill string, casing, and other heavy equipment in and out of the borehole. It works in conjunction with the crown block and the drilling line.
• The deadline anchor is a fixed point on the drilling rig where the end of the drilling line, known as the deadline, is securely anchored. This component ensures that the drilling line remains taut and properly aligned during drilling operations.
• Deadline Anchor provide accurate weight measurements secure deadlines.
• Deadline anchor is used to tie down the drill line and measure the load suspended from the top drive.
• Components of a deadline anchor: Anchor Point, Tension Monitoring System, Attachment Mechanism
• The primary function of the deadline anchor is to provide a fixed point for the drilling line, ensuring it remains in place and maintains the necessary tension during hoisting and drilling operations.
• Wireline is a multi-thread, twisted wire rope that is threaded or reeved through in typically 6 to 12 parts between the traveling block and crown block to facilitate the lowering and lifting of the drill string into and out of the wellbore.
• A wireline refers to a length of thin, flexible, high-strength wire used for various tasks related to well logging, intervention, completion, and maintenance operations. Wireline operations are critical for gathering data and performing various downhole tasks without the need to remove the drill string or production tubing
• The drawworks is a part of the system that rotary drilling rigs use for hoisting, or lifting, the drill stem and casing out of the hole. A compounding transmission, or compound, sends power from the engines to the drawworks, the rotary table, and the mud pumps.
• The primary function of the drawworks is to reel out and reel in the drilling line, a large diameter wire rope, in a controlled fashion.
• Drum Brakes are mainly used in oil industry services. They equip the brake bands of the drawworks, air clutches of the different transmissions of the drilling rigs and other wellhead equipment.
• Drawworks is a machine on the rig consisting of a large-diameter steel spool, brakes, a power source, and assorted auxiliary devices.
• FIVE MAIN PARTS OF MODERN DRAWWORKS: Drum, Power Source, Reduction Gear, Brake, Auxiliary Brake
• • Hoisting Tackle is a system comprised of two or more pulleys with a rope, cable, or chain between them.
• Hoisting tackle is typically used as a tool for lifting and lowering heavy loads.
• Storage reel stores and spools drilling line and is hydraulically powered to ease slip-and-cut operations.
• Storage reels are made to wind and unwind, with controlled tension, the drill line as the rig requires.
• The storage reel are designed for easy transport with certified lifting eyes and forklift pockets.
• A derrick is a lifting device composed of one mast or pole which is hinged freely at the bottom. It is used for lifting heavy loads and is commonly employed in construction, oil drilling, and shipping.
