100 kN Servo Controlled Universal

Automatic Bending Test Machine,

220-240 V 50-60 Hz

UTC-5556

300 kN Servo Controlled Universal

Automatic Bending Test Machine,

220-240 V 50-60 Hz

Standard

EN 12390-5, 1339, 1340, 14488-3, 14488-5; ASTM C 78, C 293, C1609, EFNARC Guidelines  for Sprayed Concrete

Servo Controlled Universal Automatic Bending Test Machines are specially configured for energy absorption capacity tests on fibre reinforced sprayed concrete specimens.

The Machines can be used;

  • for energy absorption capacity test on fibre reinforced sprayed concrete slab specimens
  • for four point bending strengths ( first peak, ultimate and residual) tests  on fibre  reinforced concrete beam specimens.
  • for EFNARC three point bending test on square panel with notch
  • for flexural strength test of concrete beams, paving flags and kerbs
  • for measuring of deflection on concrete beams

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

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.

Main Features

  • Pace rate control from 0.01 kN/s to 100kN/s (depend on the specimen stiffness.
  • 3 analogue channels for displacement transducers, extensometers, etc. built in the system as an addition to frame loadcells
  • Instrumentation amplifiers for sensor excitation andamplification
  • 1/65.000 resolution and 1.000 Hz control for each channel
  • Ethernet port for connecting to computer
  • 240x320 pixel LCD display
  • Touchscreen operator panel
  • Can execute load, displacement or strain controlled tests for post peak
  • Free of charge PC software for test control and advanced report printout
  • Multiple language support
  • Real time clock and date

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 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
