DROP TOWERS

Our products are a test system for performing single- and multi-axial impact tests on standardized products and specimens. The systems allow impact energies ranging from 0.2 to 2000 J to be set, enabling a wide range of products and materials to be tested, thanks in part to the large volume available for specimen placement.

All versions of drop towers are equipped with direct velocity readout and an automatic impactor recovery and positioning system we also offer a wide range of easily modified supports, masses, fixtures, and accessories for puncture resistance tests, tensile impact tests, and wedge peel tests along with compression and component tests

To complete the offerings in addition to the wide range of standard accessories, there is the possibility of collaborating with STEP Lab to develop the equipment that most closely matches the customer’s needs.

  • Ease of operation thanks to an intuitive user interface
  • High safety due to door locks that are activated upon machine reset
  • Pneumatic system for drop weight release
  • Automated weight lifting and positioning
  • Variable drop height
  • Impact velocity up to 5.0 m/s (up to 20 m/s with spring preload system)
  • Set of standard drop weights: weights from 0.5 to 10 kg, a total of 70 kg
  • Impact velocity acquisition at 200 kHz
  • Force signal acquisition rate up to 10 MHz
  • Rapid changeover from ISO to ASTM test equipment and vice versa
  • Wide variety of grips, dedicated test accessories
  • Integration with both strain gauge and piezoelectric load cells
