Rock Bolt Pull Out Test Machine . Application. PZ Series rock bolt pull out test machine applies to test pullout resistance of various kinds of rock bolt, anchor cable, rebar, embedded steel bars, expansion bolt, chemical anchor bolt, railspike and other anchoring parts.
Currently, it is not possible to test all rock bolt types utilising a single pullout testing system. Usu ally a special type of pullout test device has to be prepared for each kind of rock bolt since the head and manufacturing principles of each type of rock bolt are different. In this paper, a unique 45toncapacity, pull .
BS8539 Standard. We adhere to one of the most important codes of practice to affect the pull out testing industry, BS8539 Standard. Designed to provide recommendations for the safe and effective selection and installation of anchors for use in masonry and concrete, this code of practice improves the level of safety and eliminates the potential for fixing failure.
Further, our equipment comprises of the following: • Loading frame with 100kN capacity, having a base and a cross head joined together with two solid pillars with nuts. ... We offer rock bolt pull out test, which are made as per the 11309, ASTM D4435, ISRM standards. These are used to measure the working and ultimate capacities of rock ...

Mark10 Pull Testers consist of several components, each of which are available separately. These pull testers are suitable for applications such as wire terminal and wire crimp testing, connector removal testing, peel testing, and more. Configure your pull tester from a wide range of test stands, force gauges, grips, and accessories.
2013 Coal Operators' Conference The University of Wollongong 144 14 – 15 February 2013 ROCK BOLT CORROSION AN EXPERIMENTAL STUDY Naj Aziz1, Peter Craig2, Jan Nemcik1 and Faisal Hai1 ABSTRACT: The effect of long term exposure of full size bolts to corrosive environments is presented. A special test rig was used to test four bolts under different loading conditions.
Table 1 shows the summary of retrieved data of the bolt pull testing with subsequent analysis. The bond strength (kN/mm) was determined as the peak (maximum) pull load divided by the encapsulation length. Figure 4 shows the average pull test loaddisplacement profiles of the different set of test methods.
High Capacity Anchor Bolt Pull Testing Service. Pull Tests on anchor bolts for structures like cell towers, wind generation towers, communication sites, light poles. Cell tower pull tests.
Pull Out Test Apparatus. Pull Out Test Apparatus is used to measure short term strength of an installed rockbolt under field conditions. The strength is measured by a pull test, in which bolt head displacement is measured as a function of applied bolt oad to give a loaddisplacement curve.
Humboldt manufactures construction materials testing equipment for use with soil, concrete, cement and asphalt materials. Humboldt has geotechnical and soil mechanics equipment like triaxial, consolidation and direct shear involving ASTM standards.
Stressing Equipment. DSI has a large fleet of stressing equipment that enables our customers to test and lock off anchors of any size. The stressing jacks are complemented by stressing chairs, pulling heads and hydraulic pumps for safe and efficient stressing operations.
the test a pullbolt is threaded into the disc from the surface and attached by a coupling to the testing machine. The counterpre s s u r e ring of the testing machine is placed against the surface of the concrete and load is hyd r aulically applied by turning the handle of the testing m a c h i n e .
