Deadline Anchor

Deadline anchor is used as a display instrument for indicating and recording the drilling string changes in weight and pressure, helping the driller to master the working parameter and judge the drilling state in drilling operation. It’s mainly composed two parts: Body and Senor. It work together with the Weight indictor.

●Designed for ease of service and maintenance.

●Various models to accommodate common wire line sizes from 5/8 to 1-7/8 inches.

●Adjustable wire outlet direction for both floor and derrick leg mounting.

●Dual strain gauge in load cell.

●Handy service pocket.

●Rotatable drum to minimize wear and tear during slip-and-cut.

●Various models available for deadline loads up to 200,000 pounds

●Custom-made deadline anchors are also available.

Safety Benefits

●Provides a safe handling distance from the unit.

●All drum surfaces are machined to extend wire rope life.

●No chance of line jumping or crossing.

●Bit weight indicator uses a 4:1 sensitivity movement to provide a highly accurate indication of bit weight.

●Easy to use, especially with larger wire rope.

●Anchors are designed and tested for high strength, long life and exceptional accuracy.
