Automatic 500/1000kN testing machines for steel and concrete

description

Introduction
This machine has been designed for use, in the field or laboratory to perform tension tests on steel rebars up to 26 mm dia. and compression tests on cylindrical concrete specimens up to dia. 160x320 mm and cubes up to 150 mm, using the appropriate accessories.
The system includes the UTM AUTO Power and Control System (PCS) for the automatic execution of compression and tensile tests.

 

Frame
The frame consists of a very rigid structure with double acting cylinder assembly.
It includes tensile grips and it is fitted with a 150 mm travel high precision displacement transducer allowing test execution under crosshead separation control. See Technical Specifications.

The machine is supplied complete with a set of tensile holders, 4 wedge grips for flats up to 13 mm thickness, 4 wedge grips for rounds up to 26 mm dia. and 2 sets of grip liners 4 and 8 mm thick. Spherical seat and compression platens for concrete specimens are not included and have to be ordered separately (see Accessories).

 

UTM AUTO Power and Control System (PCS)
Automatically performs steel tensile and concrete compression tests when connected to the relevant accessories.
The PCS is available as stand alone control console or in the integrated Compact-Line version, where it is directly mounted on the frame side. See Ordering Information. The UTS Light software is tailored for tensile tests according to EN 6892-1 (method B) and EN 15630-1, being suitable for data acquisition and test results elaboration. See Technical Specifications.

    Coaxial electronic extensometer for round specimens from 5 to 11.5 mm dia.
  • 70-C0961/B1
    Coaxial electronic extensometer for round specimens from 11 to 18 mm dia.
  • 70-C0961/C1
    Coaxial electronic extensometer for round specimens from 17.5 to 26 mm dia.

Universal extensometers

  • 70-C0954/C
    Universal electronic extensometer, measuring base 50 to 200 mm. Complete with case.
FOR CONCRETE COMPRESSION TESTING
  • 70-S0012/1
    Set of lower platen and upper platen with spherical seat, 216 mm dia., for testing cylinders up to dia. 160x320 mm and cubes from 100 to 150 mm. To be completed with the suitable distance pieces depending on the specimen height.
    ​Weight approx.: 45 kg

Distance pieces
Made of steel, these pieces are used to reduce the vertical clearance of the compression machine to a height that is appropriate for the size of the specimen and considering that, in general, the maximum piston travel is 150 mm.
