Overview
XH-1T/2T/3T bolt tension meter (drawing instrument) is suitable for the detection of the anchoring force of anchors, anchor cables, steel bars, anchors and other anchors. It is one of the instruments required for mass inspection of bolt construction support engineering. The tension meter is composed of manual pump, hydraulic cylinder, digital pressure gauge and high voltage hose. The pump body is made of precision cast steel and has a long service life. The hydraulic cylinder is hollow self-reset type. It has a lifting handle and can be connected with the high voltage hose through a quick connector. The digital pressure gauge reads intuitively and can directly read the bolt tension value. The structure is compact, easy to carry, small size and light weight.

Principle
The Working Principle of the bolt tension gauge is: when the center hole of the jack covers the rod to be tested, select a suitable fixture to clamp the part of the rod to be tested that is exposed to the center hole; under the action of the hydraulic force of the pressure pump, the oil pressure is transmitted to the jack cylinder through YouTube, and the piston rod moves outward against the special collet; the pressure acts directly on the anchor shell, and then is transmitted to the clip. After the clip is stressed, the measured rod is clamped, and finally the rod is subjected to the outward pulling force; at this time, the pressure gauge on the pressure pump shows the corresponding force value, that is, reflects the size of the pulling force on the measured rod. If the rod is a steel bar, the size of the anchoring force on the steel bar can be measured.
Steps
1. The center hole of the jack covers the rod under test
2. Select a suitable fixture to clamp the part of the tested rod that is exposed to the center hole
3. Operate the pressure pump to generate hydraulic force
4. Observe the force value displayed by the pressure gauge
5. After the test is completed, remove the anchor manually with less force shaking and vibration
Step 6 Remove the pulling jack
