Three-Column Compression Testing Machine – 4000 kN

Three-Column Compression Testing Machine – 4000 kN

Manufactured by 3R Industries

Ideal for high-performance concrete testing, this three-column compression test has a perfect geometric shape (isostatic). This guarantees ideally centred load application on the specimen axis (perfect alignment of the cylinder axis with the ball joint axis) in accordance with standard EN 12 390-4.

The space between columns guarantees excellent accessibility to the specimen. The ergonomic working height (980 mm) allows the machine to remain on the floor, without the need to build a concrete base, enabling the operator to work in postures limiting back pain.

Industry: Civil engineering labs.

Benefits

  • Excellent compromise between footprint and performance for high-capacity concrete testing, thanks to its exceptional stiffness (deformation less than 0,75 mm at 3000 kN) and a very long guided cylinder.
  • Absence of transverse load ensure excellent accuracy.
  • High stiffness frame Class 0,5.
  • Designed in accordance with European standards (EN 12 390-4).
  • Fully machined frame, controlled with footmeter.
  • Three columns: Isostatic frame for perfectly balanced loading.
  • Oil bath ball joint in treated steel coated with Teflon for better load distribution.
  • Cylinder: Low friction composite seal and bronze guide.
  • Piston anti-drift device.
  • Mechanical centring device for quick and accurate specimen positioning.
  • Stainless steel protective grids with electrical safety detector.
  • Base designed for easy handling with forklift.
  • Treated steel platens – Hardness > 58 HRC.
  • Test chamber height: 340 mm.
  • Testing force: 4000 kN.
