CONCRETE COMPRESSION LOAD FRAME :
Capacities available:
-
600 kN
-
1500 kN
-
2000 kN
-
3000 kN
-
The welded type load frame provides stability for accurate and repeatable test results over years of operation.
-
The hydraulic power pack, control and readout units are positioned on the right-hand side of the load frame for easier accessibility, increased productivity and safer operation.
UPPER / LOWER PLATENS :
- The platens enable testing of a wide variety of cylinders, cubes, blocks or similar samples.
- Manufactured from high quality hardened and finished steel
- Surface roughness – 3.2 °m
- °165 mm and °300 mm upper platens (with ball seating assembly)
- Lower platens include centering rings for proper positioning of 100 mm and 150 mm cubes and cylinders
BLOCK PLATENS WITH SLIDING RAIL ASSEMBLY :
- Standards Compliance: EN 772-1, EN 12390-4
- Installed for testing concrete blocks and structural materials
- Sliding rail assembly allows installation without removing existing °300 mm compression platens
- Must be factory installed
- Vertical clearance decreases by 50 mm after installation
- Block Platens Lifting Assembly
- Allows easy removal of lower platen and replacement of distance pieces.
DISTANCE PIECES :
- Distance pieces are used to reduce vertical clearance between upper and lower platens.
LOADING CYLINDER ASSEMBLY & LIMIT SWITCH :
- Single-acting up-stroking ram
- Piston diameter varies according to capacity
- Maximum ram stroke: 50 mm
