Anchor testers measures a wide range of anchor strengths in construction materials.
Two models, each with two different gauge capabilities enable precision readings over a wide range of applications - from light to heavy duty loads. The standard system has a pull stroke of two inches with an option to extend to four inches. The longer pull stroke allows for complete extraction of most fixings in one simple operation. A load diffusion bridge and pyramid are available to keep reaction loads away from the anchor point.
Shown above, from left, is the Super Anchor Test System with Load Diffusion Bridge, and the Standard System with the Load Diffusion Pyramid.
The tensile load is applied to the fixing mechanically; hydraulics are used to register the load only. This enhances the systems reliability as it is not prone to hydraulic leaks. Also, mechanical loading provides smoother operation, eliminating hydraulic backlash.
The load application is achieved via a ratchet handle driving a 4:1 hydraulic multiplier; the applied load is recorded directly on a gauge mounted on the tester body. This compact design is lighter and more convenient to use than that of separate hydraulic pump and ram arrangements.
An integral movement indication is provided allowing “First Movement” to be identified as well as total displacement before failure.

Applications
Expansion,resin and undercut anchors.
Frames,anchors and screw fixings.
Structural anchors for safety harness eyebolts.
Scaffolding ring-bolts.
Safety anchors for ladder restraints.
-------------------------------------------
Reaction Load Diffusion In order to test correctly and avoid damage to the host construction material, reaction loads must be absorbed by the structure well away from the fixing under test. This can be achieved by either a load diffusion bridge or, if greater distance is required,by a load diffusion pyramid. Both of these optional accessories have large feet to minimize bearing pressure and are height adjustable to accommodate different adaptors.
-------------------
Long Pull Stroke The Standard Anchor System has a pull stroke of 2 inches (50mm) with an option to extend to 4 inches (100mm). The increased stroke has the following advantages:
Complete extraction of most fixings after test in one simple operation. When fixings are tested to failure, they usually need to be fully extracted from the base material. With plastic and other types of anchors, which fail by pulling from the base material, the extraction can be carried out without readjustment of the bridge legs.
Faster set-up saves time on multiple testing projects.Initial adjustment of the height of the Tester relative to the fixing can be made with the loading handle rather than moving the bridge legs.

Maximum load indicator.
Rubber casing for protection against shocks.
Shatter proof glass.
Built-in protection against sudden load release.
