Concrete Compression Machines

Humboldt Compression Machine

  • Perfect machine for labs, contractors and even mobile labs
  • Accuracy of ±.5% of indicated load from 2,500–250,000 lbs. (11–1,112 kN)
  • Choice of 3 digital load-indicating systems
  • Quiet-running, continuous-duty hydraulic pump
  • Supplied with platen set for 6" (150 mm) cylinders using unbonded or sulfur-capping method

The CM-2500 has all the features you look for in a basic compression testing machine: ruggedness, accuracy, compactness, versatility, and dependability, making it the ideal choice for either field trailer or laboratory testing operations. It is well suited for testing 6" x 12" (150 x 300 mm) concrete cylinders with strengths up to 7,000 psi (48.2 Mpa), or with optional platens, low strength beams. The load frame features a wrap-around box construction with each corner fully welded on both the inside and outside crosshead seams, providing the rugged stability needed for accurate and repeatable test results year after year. The machine's eye-level digital indicator, loading-control valve, and hydraulic pump are positioned on the right side of the load frame for easy access, increasing productivity, and safe operation. Featuring superior rate-of load control, its unique quiet-running, continuous-duty hydraulic pump and pressure-compensated loading-control valve are manufactured to ISO 9001 international quality standards. Exceeds ASTM C39, E4 and AASHTO T22 specifications. Stand is optional, order HCM-0200, if desired.

Humboldt Compression Machine— HCM-2500

Humboldt Compression Machine

  • Accuracy and testing range of ±.5% of indicated load from 1% to full machine capacity
  • Quiet-running, continuous-duty hydraulic pumps
  • Rigid load frames exceed ACI 363 frame-elongation requirements
  • Choice of 3 digital load-indicating systems

The HCM-3000 features a rigid load frame that exceeds ACI 363 frame elongation requirements, a wide accuracy range, easy-to-use digital load indicating systems and increased testing capacity making it one of the most versatile and affordably priced compression testing machines available in its class. Its wide accuracy range allows you to test everything from 9,000 psi (62 MPa) 6" x 12" (150 x 300 mm) cylinders, to standard 6" (150 mm) concrete beams in one machine. The HCM-3000 is built to last, compare its many proven design features to those of lighter competitive machines. It utilizes a fully welded, unique wrap-around frame design with crossheads that are 25% thicker, as well as a larger diameter piston with longer stroke and dust shield, a thicker lower platen hardened to HRC 55 or greater, and steel fragment guard doors. Stand is optional, order HCM-0300, if desired.

Humboldt Compression Machine— HCM-3000

Humboldt Compression Machine

  • Accuracy and testing range of ±.5% of indicated load from 1% to full machine capacity
  • Quiet-running, continuous-duty hydraulic pumps
  • Rigid load frames exceed ACI 363 frame-elongation requirements
  • Choice of 3 digital load-indicating systems

Designed to meet the demands of production testing laboratories where day-to-day performance is required, all CM-4000 series machines exceed both ACI 363 frame elongation requirements and ASTM C-39 and E-4 specifications for accuracy. HCM-4000 series machines are available in three different load frame configurations: Standard model height meeting ASTM C-39 specifications, B-models featuring thicker lower platens meeting ASTM C-140 specification for testing a single full sized concrete block, P-models feature an inside vertical frame opening of 26.750" (68 cm) without upper platen installed and thicker lower platen meeting ASTM C-1314 specification for testing two full size concrete blocks in prism. All three-load frame models will test a full range of specimen types. HCM-4000 models feature thicker crossheads and a wrap around frame design that extends the frame side members around the front and back of the crossheads, which are fully welded inside and out forming a solid one piece load frame, providing the frame stability needed for repeatable and accurate test results year after year, even when testing high strength concrete.

For easier operation and loading of specimens, all load frames feature a wide horizontal opening and a large lower compression platen for testing up to 12" (324 mm) wide concrete block. The lower platen is hardened to 55 HRC or greater, plated for corrosion resistance and has concentric circles for easier centering of test specimens. A dust shield protects the load frames bottom mounted piston and hydraulic seals. Steel fragment guard doors are mounted on both frame openings for operator protection. Includes mounting stand.

Humboldt Compression Machine— HCM-4000

Humboldt Compression Machine

  • Rigid load frame exceeds ACI 363 frame-elongation requirements
  • Accuracy and testing range of ±.5% of indicated load from 1% to full machine capacity
  • Thicker crossheads and side members than competitors
  • Choice of 3 digital load-indicating systems

High-capacity series compression testing machine features rigid distortion-resistant load frame designed to meet the demands of testing high-performance concrete in a production testing program where accurate and repeatable test results are required.

High-strength frame incorporates thicker crossheads and deeper side members than competitors' models. For example, the frame has a stiffness of 41.6 million lbs./in. We invite comparison of the frame design specifications to any other high-capacity machine.

For easier operation and loading of specimens, the frames feature a wide horizontal opening, large lower platen, bottom-mounted piston with dust shield, heavy-duty load-frame mounting stand that positions the lower platen at a convenient height for loading heavy test specimens, and steel front and rear safety guard doors. The lower platen is through-hardened to 55 HRC or greater, ground plane, plated for corrosion resistance, and has concentric circles for easier centering of test specimens. Includes mounting stand.

A quick-change platen system is available to assist in fast and easy switching of test platens, please call 1.800.544.7220.

Humboldt Compression Machine— HCM-5000

Block and Prism Compression Machine

  • Test block, masonry prisms, pavers, and wall retainer units
  • Testing range from 1% to 100% of machine capacity, with an accuracy of ±.5% of indicated load
  • Accessories for testing a full range of concrete andcement specimens available. Ships with cylinder platens and spacers, block platen requires special ordering.

Block Compression Testing machines are available in two load frame configurations for testing single- or two-block masonry prisms of full-sized block up to 12" (304 mm) wide. The heavy-duty load frames use the same proven design and manufacturing process found in all our machines, with a wide horizontal opening and large lower compression platen for easier loading of test specimens. The machine's mounting stand also places the lower platen at a convenient height for easier loading of heavy specimens. The unique lower dual-platen system features a wear platen through-hardened to 60 HRC or greater and is designed for fast and easy maintenance without the need for expensive rental equipment to remove the platen, unlike the cumbersome singleplate systems used in competitive units. Changing test platens and spacers is quick, easy, and safe with our draw rod, used to adjust the load frame's inside vertical working height, and optional carrier bracket system, which features a heavy-duty arm mounted on the rear left corner of the load frame that pivots on two hinged joints. When the block platen is not being used, it can be conveniently stored on the bracket's arm. Includes mounting stand.

Draw Rods are provided with all Prism Load Frame model machines. The Draw Rod is used by the operator to quickly and easily mount a wide range of test platens and spacers securely to the machines upper crosshead.
