Features:
  1.Altogether there are 16 versions of JZ Series Weight Indicating Systems ranging from 500 tons to 40 tons for different types of drilling / workover rigs. Each set of weight indicating system is composed of a JZG deadline anchor, a JZ weight indicator and a JZJ recorder. According to the way of installation, deadline anchors can be classified into two types, namely, vertical   type and horizontal   type;
