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.

Deadline anchors work for drilling rigs and workover rigs. Lines pull capacities from 30.000 pounds to 100.000 pounds. It can indicate and record the variation of hook load and weigh on bit in order to help driller judge the operation Status of the rig and obtain the proper drilling parameters during or well service operation.
