  • Test blocks, masonry prisms, pavers and retaining wall units.
  • Testing range from 1% to full machine capacity, with an accuracy of ±.5% of indicated load.
  • Optional accessories for testing a full range of concrete and cement products.

Masonry series machines are available in two load frame configurations for testing single or two block masonry prisms of full sized block up to 12" (304 mm) wide. The heavy duty load frames use the same proven design and manufacturing process found in all of our machines, with a wide horizontal opening and large compression platen table for easier loading of heavy specimens. The machines mounting stand also places the lower platen at a convenient working height.

The unique lower dual-platen system features a through hardened wear platen. It is designed for fast and easy maintenance, unlike the cumbersome single platen systems used in competitive units. Changing test platens and spacers is quicker, easier and safer with our draw rod and carrier bracket system. The draw rod uses slide on spacers to adjust the load frames inside vertical working height. The optional carrier bracket features a heavy-duty swing arm mounted on the rear corner of the load frame. The arm pivots on two hinged joints, allowing it and the block platen to rotate smoothly into and out of the load frame. When the block platen is not being used, it is conveniently stored on the bracket.

Their quiet running continuous duty .75 hp (6 kw) hydraulic pump and loading control valve are manufactured to ISO 9001 international quality standards.

Available with three different digital load indicating systems, select from a basic budget-minded unit, or an advanced unit that will automatically calculate and display stress test results and will transfer to a PC all of the test data required for a C-39 test report.

Machines are available in two model styles, as a fully self-contained machine with indicator, hydraulic pump and loading control valve mounted on the right side of the load frame. Console model machines feature a free standing console positioned on the right side of the load frame. The console houses the indicator, loading control valve, hydraulic pump and electrical system.

Standard safety features include steel fragment guard doors, a high-pressure hydraulic safety valve which prevents the machine from operating beyond its maximum capacity, and a piston over-extension limit switch on all models. Optional safety feature is an electronic overload protection switch that automatically turns the hydraulic pump off when the machine reaches its maximum capacity or at sample failure. This option is available only on machines equipped with iD and LXI indicators

Optional test platens and spacers are available for testing a wide variety of specimen types. Machines meet ASTM C-39, C-140, C-1314, E-4 and AASHTO T-22 specifications. All models have a two year warranty on parts and labor.
