The machines digital indicator, loading control valve and hydraulic pump are positioned on the right side of the load frame for easy accessibility, increased productivity and safer operation by positioning the operator to the side of the load frame opening during testing. Featuring superior rate of load control, its unique quiet running continuous duty hydraulic pump and pressure compensated loading control valve, are manufactured to ISO 9100 international quality standards.

Available with four different digital load indicating systems to choose from. Select a basic budget minded unit or an advanced system that will automatically calculate and display stress test results at the end of a test.

The CM-2500 Series machines are available in two model styles, the standard self-contained machine in models CM-2500-DI, DIR, LXI and iD or with a separate freestanding console model CM-2500-D.

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.
