Drop weight towers
ACCURATE PERFORMANCE ANALYSIS OF SINGLE AND MULTI AXIAL IMPACT OF MATERIALS AND PRODUCTS
The DW 1000 is a drop tower test system that performs mono-multi axial impact tests on products and specimens. The system allows to set impact energies ranging from 5 to 750J, allowing to test a wide range of products and materials, also thanks to the large volume of work available for the positioning of the sample.
The DW 1000 allows to perform both broken / not broken tests and instrumented tests, in which acquires strength and energy absorbed during the impact.
The system is developed to be easily customized and upgraded in order to meet current and future requirements of the client.
All versions of DW 1000 are equipped with a direct reading of speed, automatic recovery and positioning system of the weight.
A wide range of standard accessories is available. For special requirements STEP Lab is ready to collaborate with the customer.
Application areas
Reliable test results, the robust chassis absorbs shock and vibration providing more accurate results
Robust guides make the drop weight towers ideal for component testing
The modular structure allows a wide range of applications
Direct reading of the speed and automatic recovery and positioning system of the impactor

Accessories
Starting from the basic mechanical and software structure of the machine, further accessories for impacts on all types of components can be easily realized. Below are the accessories currently in the catalogue:
The debounce system holds up the drop weight thus preventing further secondary impacts affect the physical state of the sample / product.
Spring preload system allows to increase the speed of the impact (the management of the module is fully automated)
The drop tower can be equipped with a refrigeration circuit climatic chamber for temperatures from -40°C to +180°C. The cell management is integrated in the fall tower software.
The drop tower can be equipped with a nitrogen climate cell for temperatures rane from -80°C to +180°C. The cell management is integrated in the fall tower software.
STEP Lab is flexible in the production of specimen supports for any type of standard or custom.
