Manual Compression Testing Machines
CM-3250 Series
Meets ASTM C-39, E-4 and AASHTO T-22 specifications.
Available in Automatic and Manual Control
- Testing range of 3,250 to 325,000 lbs. (14.45 – 1,445.67 kN) with an accuracy of ±.5% of indicated load.
- Choose a basic budget-minded digital or an advanced indicator that automatically calculates and displays stress test results.
The CM-3250, with its American-made, rigid steel welded load frame, is built to last. The upper and lower crossheads are 4 inches thick with a ram that is 7 inches in diameter. These features make the CM-3250 one of the strongest machines in its class.
The load frame is manufactured with structural steel side members and solid steel crossheads. Also featuring our wrap-around box construction design with each corner fully welded on both the inside and outside crosshead seams. Which provides rugged stability needed for accurate and repeatable test results year after year.
The CM-3250 comes ready to test 6x12 concrete cylinder. With additional spacers and accessories it can test 2x4,3x6, and 4x8 cylinders, beams, 2-inch cement cubes, and conduct splitting tensile strength tests.
The digital indicator, loading control valve and hydraulic pump are positioned on the right side of the load frame for easy access, increased productivity and safer operation. Featuring superior rate of load control, its quiet running, continuous-duty hydraulic pump and pressure compensated loading control valve are manufactured to ISO 9001 international quality standards.
Available with four different digital load indicating systems, you can select from a basic budget-minded unit or an advanced unit that will automatically calculate and display stress test results and transfer all the test data required for a C-39 test report to a PC.
Standard safety features include steel fragment guard doors on both frame openings and a high pressure hydraulic safety valve which prevents the machine from operating beyond its maximum capacity. Optional safety features include a piston over-extension limit switch (available on all models) and an electronic overload protection switch. This switch automatically turns the hydraulic pump off when the machine reaches its maximum capacity or at sample failure, and is available on iD models only.
Optional accessories include test platen sets, spacers, machine mounting stand, test cylinder loading shelf and ¾ hp (.6kw) hydraulic pump package.
Warranty 2 years on parts and labor.
