ROCK BOLT PULL OUT TEST APPARATUS AZA1006
AZA1006 Rock Bolt Pull Out Test Apparatus is a high-precision, field-grade hydraulic testing system designed to determine the anchoring strength and load-bearing capacity of rock bolts, anchor bars, and grouted tendons directly in-situ. It is widely used in mining, tunneling, underground excavation, dam construction, and slope stabilization projects to verify the safety and performance of installed support systems.
This rugged and portable apparatus allows engineers to apply a controlled tensile load to rock bolts and measure both ultimate pull-out force and displacement. By simulating real-world tensile stresses, it helps evaluate grout bonding quality, rock mass interaction, and overall installation effectiveness before final commissioning of underground structures.
As underground infrastructure grows, ensuring the reliability of anchoring systems is critical. AZA1006 delivers dependable performance through its hydraulic pull mechanism, precision pressure monitoring, and easy-to-deploy field design, making it an essential tool for geotechnical safety assurance.
Description
What is a Rock Bolt Pull Out Test?
A pull-out test measures the maximum tensile force a rock bolt can withstand before failure or excessive deformation. The test helps assess:
-
Anchoring strength of the bolt
-
Bond integrity between grout and rock
-
Load-transfer behavior of the anchoring system
-
Quality of installation workmanship
This test is performed directly at the site, making portability and durability critical — both of which are core strengths of AZA1006.
