Manual Compression Testing Machines

CM-3000 Series

CM-3000 Series CM-3000 Series

Meets ASTM C-39, E-4 and AASHTO T-22 specifications.

  • Testing range of 3,000 to 300,000 lbs. (13.3 – 1,334 kN) with an accuracy of ±.5% of indicated load.
  • Load frame stiffness of 10.5 million lbs/in, stronger than any competitive machine in its class.
  • Choose a basic budget-minded digital or an advanced indicator that automatically calculates and displays stress test results.

The CM-3000 features a rigid load frame, increased testing capacity, easy to use load indicator, and large lower compression platen. With this configuration, cylinders with pad cap rings can be slid into place without being lifted. These features make the CM-3000 one of the most versatile and affordably priced testing machines available in its class when compared to competitive models.

Built to last, compare its many proven design features to those of lighter competitive machines; its crossheads are 25% thicker, larger diameter piston with longer stroke and dust shield, a thicker lower platen table through hardened to HRC 55 or greater and steel fragment guard doors.

Its load frame is manufactured with structural steel side members and solid steel crossheads, and features our wrap around box construction design with each corner fully welded on both the inside and outside crosshead seams, for the rugged stability needed for accurate and repeatable test results year after year.

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 by positioning the operator on the right side of the machine when testing. 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 three 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 will transfer to a PC all of the test data required for a C-39 test report.

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 and TS17 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.
