About our Scaffold Tester
The new NASC/CFA Guidance Note TG4:04* Anchorage Systems for Scaffolding sets out requirements for PRELIMINARY TESTS of scaffold anchors (to check the suitability and allowable loads of an anchor type in a particular base material) and PROOF TESTS (sample tests to check that anchors have been installed correctly – to be carried out on all jobs).

This will enable you to satisfy the HSE SCAFFOLDING PROTOCOL pre-start checklist.

The new Proof Load testing requirement is for a tensile test of 1.5 x the design load. For heavy duty ties with a capacity of 12.2kN this means a test load of 18.3kN.
TG4:04 also describes six types of anchor most commonly used for anchoring scaffold ties. The Hydrajaws Scaffold Tester Kit will test all types to a maximum tensile load of 20kN.
