300 kN Servo Controlled Universal Automatic Bending Test Machine

TC-5556 Servo Controlled Universal Automatic Bending Test Machine is specially configured for energy absorption capacity tests on fibre reinforced sprayed concrete specimens. The machine can be used for:

  • Energy absorption capacity test on fibre reinforced sprayed concrete slab specimens
  • Four point bending strengths ( first peak, ultimate and residual) tests on fibre reinforced concrete beam specimens.
  • EFNARC three point bending test on square panel with notch
  • Flexural strength test of concrete beams, paving flags and kerbs
  • Measuring of deflection on concrete beams
  • The machine consist of extremely high stiffness frame and servo controlled hydraulic power pack.

    Loading Frame

    The frame of machine is designed torsionally stiff up to the maximum load of 300 kN with anti-rotation system to prevent the natural tendency to rotate the columns of frame. The four columns of frame are clamped with zero clearance. Test cylinder mounted on the top crosshead has double-action with long piston stroke in servo slide quality (particularly low friction). The displacement measurement is achieved through the displacement transducer built in piston. A directly actuated servo-valve is mounted on the test cylinder, to ensure a quick and highly precise process during testing. An anti-rotation device prevents twisting the piston rod from twisting with the top bending beam and the precision load cell. The test chamber contains adjustable supports. The top bending beam can be very easily modified from the 3 point test to the 4 point test. Optionally, other test devices are available for installation. The drive and controls are located in the separate power pack.

    Power Pack

    The power pack contains a hydraulic pump and a fine flow oil filter. The hydraulic unit consists of a high-pressure radial piston pump. All operating and control elements are located on the power pack. The powerpack consists of oil level indicator, high temperature indicator, mechanical filter clogged indicator and cooling unit. Different tests with automatic test sequence can be performed by help of the free software. The accessories for different tests should be ordered separately.

  • Data Acquisition & Control Software

    Servo Controlled Universal Bending Test Machine can be controlled (Start, Stop commands) by a computer with the free of charge software supplied with the machine. This software provides data acquisition and management for compression, flexure and splitting tensile test throughout the test execution. The engineering values such as modulus, toughness, energy has been supported. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Test parameters can be set and details about the test carried out such as customer details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.
