back to top»2" Cube Platen Test Set

  • Test both cubes and cylinders.

Used for testing 2 (50 mm) cubes and 3 (76 mm) diameter cylinders and cores in compression. Cube test set consists of a spherically seated platen assembly and a lower pedestal used for positioning the cube sample at the correct height for testing.

The bearing block of the upper platen is hardened to 60 HRC and plane to .0005 (.01 mm). The upper bearing block is closely held in its spherical seat, but is free to tilt in any direct and seat securely under load.

The platen is easily installed in the upper crosshead of the load frame and is securely held in place by either the holding stem, allen bolt or draw rod system.

Spacers are required for testing 3 diameter cylinders or cores. Cube pedestal is not used when testing cylinders or cores.

Meet ASTM C-109, C-1604, C-39 and AASHTO T-22 and T-106 specifications.

back to top»Carrier Bracket

  • Easier and safer mounting of Block Platen

The Carrier Bracket is used for safer removal and mounting of the block platen assembly inside the load frame, and should be considered a must have option when testing masonry units.

The brackets heavy duty arm is mounted on the rear left hand corner of the load frame and pivots on two hinged joints, allowing the complete assembly to rotate smoothly into and out of the load frame. When not in use platen and arm are conveniently stored on rear of machine.

Carrier Bracket option is available on all CM-4000 through CM-1000 series machines.


back to top»Cylinder Loading Shelf, CM-2500 Series

  • Easier loading of 6 cylinders in CM-2500 series machines.

This optional shelf was designed to make loading and positioning of 6 (152 mm) cylinders with pad cap rings both easier and safer in a CM-2500 series machine.

The shelf features a heavy-duty steel design with a plastic laminated top, so cylinders with retainer rings slide smoothly onto the frames lower test platen.

MA-0135 Cylinder Loading Shelf option


back to top»Draw Rod

  • Safer, easier and faster changing of test platens and spacers.

The draw rod system is used to adjust the inside vertical working height of the load frame, to allow for testing samples of different heights through the use of spacers and test platens. The system is made up of a steel hand wheel with internal ball bearings and a threaded rod that is easily raised or lowered inside the load frame for height adjustment. Spacers slide onto the rod, the rod is threaded into the test platen, and the assembly is then tightened against the crosshead.

Draw rods are included with all prism load frame model machines, and can be purchased as an option for all CM-4000 through CM-1000 machines.

back to top»Flexural Beam Attachment

  • Test both Center and Third Point beams with this universal attachment.

Used to determine the modulus of rupture of Center or Third Point beams with a depth of 6 (150 mm).

The upper heads load bearing blocks are easily changed for either a center or third point testing configuration. Bottom support blocks are set in the lower support channel with a fixed 18 (457 mm) span length.

Meets ASTM C-78, C-293, AASHTO T-97, T-177 specifications.

back to top»Masonry Platens

  • Models available for testing 12 (305 mm) and 8 (203 mm) wide masonry units.

Both models feature large diameter spherical disk and seat assemblies, and platen bearing surface plane to .001 (.025 mm) in any 6 (152 mm) direction, through hardened to HRC 60 and plated for wear and corrosion resistance. The bearing block is held securely in it seat assembly by a series of heavy duty springs and safety links which allow it to rotate freely and seat under load.

The MA-0107-P is used with units up to 12 (305 mm) wide and meets ASTM C-140 and C-1314 specifications.

back to top»Spacers

Spacers are used with test platens to adjust the vertical working clearance height inside a machines load frame, for testing samples of various types and sizes to prevent over-extension of the load frames piston.

They are manufactured from steel and machined plane on both ends to maintain a parallel alignment between spacers and test platens. Spacers are painted for corrosion resistance.

Spacers are available in four model types; three model types for mounting against the machines upper crosshead by the holding stem, socket head bolt or draw rod methods, and one model type that sits on the machines lower crosshead used with a bearing platen.

Our sales department will quote you the required spacer for your application for sample type and machine model.
