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.
