Pullqit™ Anchor Test™ System

The Pullqit™ Anchor ™ is designed for testing fixings, fasteners and anchors. It consists of a mechanical screw arrangement acting through a hydraulic load cell, which measures the load applied to the anchor directly. The resulting load value is then indicated on the dial type analog gauge. A maximum load indicator on the gauge provides reliable results whether the anchor is tested to failure or can be set for load verification purposes.

The Pullqit™ Anchor Test System involves bonding a circular steel disk to the surface by means of an epoxy resin adhesive. A controlled tensile force is then applied to the disk and failure will occur at the weakest point: either in the host material, or in the bond between overlay and host material.

The alignment plate has two 360 degree bubble levels built in to facilitate set up, allowing a direct tensile pull from the surface of the material under test. The level can be easily adjusted by utilizing the thumb screws attached to the adjustment legs.

There are also two magnets that hold the pull assembly to the plate. This eliminates the tedious need for screws to keep the two assemblies together when transporting the system from one test to another. Yet it still keeps the system compact for storage and transportation.

For Proper testing, it is first necessary to cut through the overly under test directly to the substrate underneath. In the case of paints, thin coatings and overlays this can simply be accomplished with a fine exacto knife or similar sharp tool. In the case of concrete overlays, asphalts, tiles or similar repair mortars this can only be accomplished by coring saw or drill.

Failure can typically occur in either one of three modes:

• in substrate
• at the substrate overlay interface
• in the overlay.



Tests can also be performed for verification purposes and not to failure. This will assure the engineer that both the overlay and substrate have 'bonded' and further work or use can proceed.

Pullqit™ Anchor Test System features a ball joint pull disk design. This assures that the pulling force is always in tension even if the pull disk is uneven due to irregularities in the overlay surface. This also creates a rapid test setup as the ball end of the disk simply slide into the Bond Test Puller.

  Frequently Asked Questions :

  Q. Bond disk will not stick to surface
  

  A. The Epoxy may have been mixed with unequal parts of Resin & Hardener; causing it to not cure fully. Also, the temperature may be too cold for the epoxy to harden. Thus, more time or a higher temperature is needed for the epoxy to cure.
  

  
  

  Q. disk pops off surface at a low strength
  

  A. Surface may not have been cleaned properly. A good indication of this would be little bits of concrete stuck to the bottom of the disk. You may also not have a level surface.
  

  
  

  Q. When doing a test to check bonding strength on a roadway, do you have to take the test to failure?

  A. Yes and no. Make sure you follow the specs for each job you do, some may want you to take it failure, while others may want you to just take it to a certain strength.

  
  

  Q. When I crank the handle down, the gauge does not move.

  A. Chances are you need to fill the puller with oil.

  
  

  Q. How much epoxy do I put on the bond disk?

  A. You need just a thin layer, about 3 for 4 sheets of paper.
