Technical overview

The test frame features extremely high stiffness and natural resonance; high-accuracy alignment avoids unwanted flexural stresses in the specimen.

 

Description

  • Dynamic testing machines in the HB range are available in various versions for test loads from 50 to 2500 kN.
  • Standard testing actuator stroke of 100, 250 or 400 mm.
  • Can be supplied for 210 or 280 bar system-pressure.
  • Load cell can be attached to the piston rod or lower crosshead as required.
  • Adjustable upper crosshead. The version with hydraulic crosshead clamping and lift cylinders is recommended.
  • Testing system can be tailored to customers’ individual requirements (e.g. specimen grips, test fixtures, extensometers or testing software).

Advantages & features
