Massive tensile testing machines

These massive machines have load capacities of 500 kN up to 15 000 kN.  Smaller size, vertical hydraulic testers are also available.

This series of hydraulic tensile testing machines are suitable for tensile tests for anchors and anchor chains used on ships, steel-wire rope, cables and other flexible specimens.    The load frame for this series is of a horizontal construction, and the testing space can be adjusted according to the requirements of the user.

The PC and electro-hydraulic servo system controls the actuator to add the testing load, so it can automatically perform tests requiring constant load rate,  constant displacement rate, cycling, creep (constant load), or stress relaxation (constant displacement).  The user can also use the automatic control to create more complex load sequences through the intelligent programming system. The Windows software will automatically collect the testing data and curves, display results with automatic processing, and stored the data onto disc.  The machine is also equipped with an Ethernet system interface.

A 2000kN machine with tensile clearance of 17000mm and ram stroke of 1000mm is shown in the picture, set up for one customer’s application.   The accuracy of the specimen elongation is to within 1% FS, and test load accuracy can be 0.5% of the indicated value. The resolution of crosshead displacement is 0.02mm.  

These hydraulic tensile testing machines are available in Australia and New Zealand from Technical and Scientific Equipment.
