300K Compression Machine, iD Digital, 1/2 hp


CM-3000 300,000 lbs./1334 kN Capacity

ü Accuracy and testing range of + .5% of indicated load from 1% to full machine capacity
exceeds ASTM C-39 and E-4 specifications.

ü Quiet running continuous duty hydraulic pumps

ü Rigid load frames exceed ACI 363 frame elongation requirements

ü Four digital load-indicating systems to choose from, select a model with automatic stress
calculation display or a basic budget minded unit.

These machines are designed to meet the demands of production testing laboratories where day-to-day performance is required. They exceed both ACI and ASTM requirements for frame elongation and accuracy.

Built for years of dependable service both load frames feature thicker crossheads and our wrap around frame design, which extends the frames side members across the front and back of the crosshead. The frame is then fully welded on both the inside and outside crosshead seams forming a solid one piece load frame for the stability needed for repeatable and accurate test results year after year, even when testing high strength concrete.

For easier loading of test specimens both frames have a wide horizontal opening and a large lower compression platen. The platens are through hardened to 55 HRC or greater, ground plane, plated for corrosion resistance and have concentric circles for easier centering of test specimens. Their bottom-mounted pistons are larger in diameter than those of competition models and are protected by a steel dust shield that keeps their hydraulic system cleaner.

For the operators protection steel fragment guard doors are mounted on both frame openings. Test platens and spacers are mounted to the top crosshead and can be changed in a matter of minutes.

Their quiet running hydraulic pump is rated for continuous duty with all of its components and those of the loading control valve manufactured to ISO-9100 international quality standards. The control valve is pressure compensated for a smooth and constant rate of loading, meeting the test specification requirements of a wide range of specimens.

Select a digital load indicating system that meets your testing requirements. Choose from four easy to use models, all having the same wide accuracy range of + .5% of indicated load from 1% to full machine capacity, which exceeds ASTM C-39 and E-4 requirements.

The DI and DIR are our basic budget minded models, while the LXI and iD models offer advanced features such as automatically calculating and displaying stress test results. Optional accessories will also allow the LXI and iD to print or transfer to a PC all of the data needed for a C-39 test report. The LXI model will also print an X-Y load or stress vs. time graph with a test information header of the current test.

These machines are available in two model styles, as a complete self-contained machine in models DI, DIR, LXI and iD or with a separate freestanding console model D. Besides the benefits of their space saving design, the self-contained model configuration also promotes increased productivity, easy accessibility and safer operation by positioning the operator to the right of the load frame opening during testing. This is accomplished by mounting the digital indicator at eye level on the right side of the load frame directly above the control valve and hydraulic pump, which positions the operator in close proximity to all of the machines control functions.

Console model machines normally have the control console positioned on the right side of the load frame, with the digital system, control valve, hydraulic pump and electrical components housed within it. The consoles 30º-sloped face allows for easier reading of the digitals display and the close arrangement of the hydraulic control valve to the digitals keypad also promotes economy of movement for the operator.

Standard safety features include; steel fragment guard doors on front and rear load 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 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 on SD, DB and D models only.

Optional test platens and spacers are available for testing a wide variety of specimen types. Machine mounting stand is an optional accessory on CM-3000 series machines.

Machines meet ASTM C-39, E-4 and AASHTO T22 specifications. All models have a two-year warranty on parts and labor.
