Abstract
A tension indicator used on a guy line system of an inclined oilwell derrick, comprising a hydraulic compression load cell, a pair of interlocking U-shaped yokes housing the load cell between the bases of the U-shaped portions, a plunger connected to the load cell bearing against the base of one interlocking yoke, the load cell bearing against the base of the other interlocking yoke, a walking load binder mounted on the outer end of a first interlocking yoke and providing an initial tension load to the guy line system, a threaded nut and screw adjustment assembly affixed to the outer end of a second interlocking yoke and providing a finer adjustment of the tension provided by the walking load binder, a pair of attachment hooks rotatably mounted on the outer ends of the tension indicator device for inserting the tension indicator device between a set of intermediate chains connected in a guy line, and a calibrated pressure gauge directly attached to the load cell; whereby the interlocking yokes transfer a linear tension load in the guy line into a compressive in the load cell; by and wherein the compressive force is transmitted as a pressure signal to the pressure gauge.
