Automatic Flexural Testing Machines

Automatic range of 100 kN, 200 kN, 300 kN and 400 kN capacity Flexural Testing Machines have been designed for reliable and consistent testing of flexural test on standard concrete beams, concrete or natural stone kerbs, concrete paving flags, and natural stone slabs and tensile splitting test of concrete paving blocks with suitable apparatus.

Machines confirm all EN, ASTM and BS standards written above. These also meet the requirements of CE norms for the safety and health of the operator.

Tests can be performed by either Digital Readout Unit or on a computer with using free Software.

The Automatic Flexural Testing Machines allow inexperienced operators to perform the tests. Once the machine is switched on and the specimen is placed. The only required operations are;

• Setting test parameters, including pace rate (only required when the specimen type is changed).

• Pressing the START button on the control unit

• The machine automatically starts the rapid     approach switches the test speed after 1% of the load capacity of the machine and stops once the specimen failure.

The Natek ranges of Flexural Machines have the accuracy of Class 1 start¬ing from 2% of the full capacity.

The Automatic Flexural Testing Machines consist of;

• Heavy Duty Welded Load Frame,

• Automatic Hydraulic Power Pack,

• Digital data acquisition & control system,

Flexural test assemblies should be ordered separately.

The multipurpose Flexural Testing Frames are designed for minimum deflection at maximum load resulting in very high accuracy. The load frame is a welded steel fabrication carrying the ram fitted to the steel base. All Frames have a single acting up stroking ram with over travel switch protection to stop the machine when maximum ram travel is reached. A load cell is used for load measurements on all frames.

Flexural Frames are designed to accept all accessories required for flexural or compression tests.

Flexural Frames are 100 kN, 200 kN, 300 kN capacity U Type and 300 kN, 400 kN capacity C Type open structure designed to allow easy and practical front loading of the specimen.

The very rigid C type design is ideal either for conventional flexural test or for more sophisticated tests such as deformability and ductility index.

The load frame provides the stability needed for accurate and repeatable test results over the years of operation.

All frames can be connected to compression machine as a second frame or can be used with any Natek power pack as an independent Flexural Machine.

• High stability welded assembly

• High accuracy load measurement with load cells

• Can accept wide range of accessories for mentioned standards

• Can be connected to HİRA Compression Machine or Hydraulic Power Pack

Flexural Testing Assembly for Concrete Beams

The test assembly is used for 3 or 4 point flexural tests on 100 or 150 mm Concrete Beams. The set consist of 2 upper and 2 lower rollers of Ø38 x 160 mm.

The distance of lower bearers can be adjusted between 100 mm and 800 mm. The distance between upper bearers can be set to 100 mm or 150 mm.

For 3 point testing one of the bearers can be removed and the other placed in the center.
