Servo Controlled Universal Automatic Bending Test Machine is specially configured for energy absorption capacity tests and also other tests of fibre reinforced sprayed concrete specimens.

The Machine can be used;

• -for energy absorption capacity test on fibre reinforced sprayed concrete slab for four point bending strengths ( first peak, ultimate and residual)  tests  on fibre reinforced concrete beam specimens.
• -for flexural tensile strength (limit of proportionality (LOP), residual) for metallic fibre concrete
• -for findout to effect of fibres used in concrete on strength of concrete
• -for flexural strength test of concrete beams, paving flags and kerbs
• -for measuring of deflection on concrete beams
• -for large specimens (slab, flagstones), concrete beams and kerbs

 The machines consist of extremly high stiffness frame and servo controlled hydrolic power pack.

The machine is supplied complete with UTM-8516 (Ø:165 mm Lower and spherical seated upper loading platens), distance pieces (15mm - UTCM-4630, 30 mm - UTCM-4631, 50 mm - UTCM-4633 and 100 mm - UTCM-4634). Other suitable accessories should be ordered separately acc. to the test performed.

Load Frames

The frames of machines are designed torsionally stiff up to the maximum capacity 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 accessories İncluding energy absorption capacity test assemblies on the frame can be easily removed and the test accessories suitable the test to be performed can be installed.

Different sized frames can be availableon request.

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 type tests with automatic test sequence can be performed by help of free software.

Data Acquisition & Control PC Software

Servo Controlled Universal Bending Test Machines can be controlled (Start, Stop commands) by a computer with the Free of Charge software (USOFT-5621.SVD2 or USOFT-5641.SVD2) 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.

Safety Features

• -Maximum pressure valves to avoid machine overloading
• -Piston travel limit switch
• -Emergency stop button
• -Software controlled maximum load value

Optional Accessories
