Hydrajaws - About Us

What we do

At Hydrajaws we develop, manufacture and sell a range of portable testers for testing the crucial holding force of anchors and fixings in construction materials.
 
For over thirty years our testers have been confirming the on-site safety of fixings in countries worldwide. With our extensive knowledge and expertise, we are regularly approached to provide solutions for a particular testing requirement.
 
 
Our wide range of testing models can confirm a wide variety of vital items including: anchors, material bond strength, adhesives and lifelines.
 

Our Products

The Hydrajaws fixing tester comprises of a hydraulic cylinder contained within an aluminium body and connected to a turning handle. At the opposite end is an attachment for securing the fixing, while a dial type pressure gauge with maximum load pointer gives a reading of the loading as it is progressively applied through rotation of the handle. Several models are available including the popular medium duty model with maximum capacity of 25 kN and the heavy duty version of 145 kN.
 
 
The testers are designed to suit the requirements of various testing procedures and standards including BS5080 and the Construction Fixings Association (CFA) in respect of installed fixings. Testers are in kit form complete with carrying case and all the necessary accessories including a load spreading bridge. The latter item is of special significance as it provides an unsupported area around the fixings, so giving a true value of both the mechanical efficiency of the anchor itself and the strength of the concrete or masonry into which it has been installed. This is of special importance where old buildings are concerned.
 
Fixings which may be accommodated include stud projections, threaded inserts, eyebolts for safety harnesses, scaffold ring bolts, remedial wall ties and other fixing systems for which selection of adaptors are available.
 
We also provide an annual calibration service to ensure the gauges are kept accurate and working correctly to ensure confidence in testing results.
 

Our reliability

Hydrajaws products are built to last and built to cope with the job they were designed for. Breakdowns and malfunctions are rare and it is not unusual for a tester to come back to us for calibration after 20 years - still working and still in use!
 
Any problems with a tester, or any testing problems, are looked into by our experienced technical team who will find a solution quickly to provide a satisfactory answer.
 

Our future

At Hydrajaws we are constantly looking into new technology and methods to improve and upgrade our products to improve usability and accuracy without compromising safety. 
 
Our basic original testers, adaptors and bridges have all undergone improvements and changes to reflect the needs of the testing market. Even our more advanced Bluetooth digital gauge has been refined and enhanced, and is currently in its third generation.
