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. It also features our wrap-around box construction design with each corner fully welded on both the inside and outside crosshead seams, which provides the rugged stability needed for accurate and repeatable test results, year after year.
The CM-3250 comes ready to test 6" x 12" concrete cylinders. With additional spacers and accessories, it can test 2" x 4", 3" x 6", and 4" x 8" cylinders, beams, and 2-inch cement cubes. It can also 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 a 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.
Standard safety features include steel fragment guard doors on both frame openings and a high-pressure hydraulic safety valve that prevents the machine from operating beyond its maximum capacity.
Optional safety features include: a piston over-extension limit switch for all models and an electronic overload protection switch that automatically turns the hydraulic pump off at either sample failure or when the machine reaches its maximum capacity (iD model only).
Optional accessories include test platen sets, spacers, and machine-mounting stand.
Warranty is 2 years on parts and labor.
