Our standard load frames are available in configurations for testing many different sizes and types of concrete strength specimens and can be equipped with high-accuracy and easy-to-operate Pro or Pro-Plus electronic controllers. Both exceed industry standards for accuracy.

Load Frame capacities range from 250,000 to 500,000lbf (1,112 to 2,224kN) for our standard 250, 300, 400, and 500 series, or we can help you design a custom compression machine with capacities up to 1,000,000lbf (4,448kN) to test a wide range of concrete sample types and sizes. Each frame can be fitted with a number of fixtures to allow testing of different concrete specimen types. Our frames exceed the American Concrete Institute (ACI) recommendations for stiffness with solid steel crossheads from 3 to 6in (76 to 152mm).

  • Pro Controllers simultaneously display live load and rate of load during testing and are accurate to ±0.5%. The peak load and average load rate are shown at the end of the test. Up to 600 tests can be stored in memory for later downloading to a PC or serial printer.
  • Pro Plus Controllers display load, load rate, and stress during a test and final load, average load rate, and peak stress at the conclusion. Test results are automatically stored for hard copy documentation and the Pro-Plus performs live X-Y plotting of load vs. time. The Pro-Plus features options for sending data to a printer for plotting, graphing, and reporting. Up to 500 tests can be stored in memory and printed in a spreadsheet format.
