Anchor Pull Test Strength Testing
Testing the pull out strength of construction fixings is becoming an essential and legal part of health and safety in the building industry.

Hydrajaws has built and developed a range of Pull Test Equipment and Accessories to determine the reliability and load capacity of fixings including Pull Test Kit for Scaffold Anchors, Anchor bolt testers, Scaffold Tie Tester Kits, Safety Lifeline Testers, Material Bond Testers and Rebar Testers.

See our product page for the full range of Testers and Accessories or call Hydrajaws on +44(0)1675 430 370 for advice on your requirements.

There has been a major increase in the use of testers, particularly with local authorities who demand that a specific testing programme should be carried out on site by the contractor which is then endorsed by recorded evidence. 

It is therefore essential that all such site personnel should be thoroughly familiar with the use and understanding of testing equipment, especially if you have recently purchased a Pull Test Kit for Scaffold Anchors or any tester in our range. In this respect Hydrajaws offers an operator training scheme and issues certificates of competence which are recognised by local authorities and others in the industry.


Hydrajaws construction safety products, including scaffold safety equipment, used in conjunction with the Hydrajaws Bluetooth Digital System can provide reassurance and confidence in the building and erecting of scaffold systems.

See the original Hydrajaws Model 2000 Scaffold Tester for a specialist tester designed to ensure your scaffolding ONLY comes down when YOU want it to.

 Tester not working?  

It is rare for our testers to breakdown and most of the time the answer is an oil refil.
