Description

Featuring almost the same performances of the HPU 200 Series at a more affordable price thanks to the application of the AUTOMAX T technology.

High flexibility covering the following applications:

  • Steel
    • Tensile tests on steel rebars and rounds up to 50 mm dia.
    • Tensile test on steel flats up to 60 x 90 mm
    • Tensile tests on wire strands and electro-welded steel screen
    • Transverse tests on steel specimens
    • Bend and re-bend tests on steel specimens
    • Brinnel with 10mm ball
    • Shear tests on rounds
       
  • Concrete
    • Compression tests on cubes and cylinders
    • Flexural tests on concrete beams
    • Indirect tensile on cylinders, cubes and paving blocks
    • Determination of the Modulus of elasticity
    • Pull out test
       
  • Various
    • Compression tests on rock, masonry units, refractories etc.
    • Wire rope tensile tests
    • Nut and bolt testing
    • Tensile test on headed and shouldered specimens
       

This model is controlled by the new AUTOMAX T control unit and is complete with PC, upper and lower hydraulically operated jaws, complete set of grips for rounds and flats, transverse test attachment and high precision load cell providing high accuracy from the very beginning of the load scale.

Loading frame
The frame consists essentially of a robust four columns frame with three sturdy crossheads: upper is directly connected to the lower one by two main columns; the middle one, moving on two screw columns, can be adjusted through an electric motor by using the dedicated push button panel, in order to set  the required vertical daylight both for compression and tensile tests; the lower is controlled by a simple effect piston centrally positioned. Jaws and wedge grips are included. The tensile jaws are operated by a separate Hydraulic Gripping System with dedicated a push-button panel. The compression tests are performed  between the lower and the mobile middle crossheads, using the suitable accessories.

Power and control console - Automax T
Control console AUTOMAX T features space-saving ergonomic design with small footprint and houses the hydraulic power unit, the electronic system and the PC to manage all the control functions.
Automatically performs steel tensile testing, compression, splitting tests, Elastic Modulus and Poisson's ratio determination on concrete specimens. See Accessories.
PC and software enable remote control of the complete system.

For more info see Technical Specifications.

Safety features

  • Pressure valve that automatically stops the machine when the oil pressure approaches the limit
  • Maximum travel limit switches to control the position of the mobile crosshead
  • Software stops the machine when the maximum load is reached
  • Emergency stop button
