DROP TOWER SYSTEMS FOR IMPACT TESTS
At STEP Lab, we offer a wide range of drop towers and impact test systems engineered for exceptional performance. Our drop towers are able to conduct both single and multiple axial impact tests on standardized products and specimens. With an expansive impact energy range from 0.2 to 2000 J, our drop towers are versatile and suitable for a wide variety of products and materials. The large volume available for sample placement further enhances the testing capabilities of our systems. In addition, we provide a comprehensive selection of accessories, including load cells, anti-rebound systems, spring accelerators, and an impressive array of instrumented impactors and specimen holders. Explore our drop towers and impact test systems and find the right one for your business, in order to achieve accurate and repeatable results.
All versions of our drop towers are equipped with direct velocity readout and an automatic impactor recovery and positioning system.
For our impact test systems, 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.
In addition to all possible drop tower standard accessories, there is the possibility to collaborate with us to develop the equipment that most closely matches your needs.
