Drop Weight Impact Testing Facility

The National Drop Weight Impact Testing Facility is a unique, state-of-the art technology funded by the Australian Research Council and built by local engineering firm Austeng. The facility is a result of a joint collaboration between 7 Universities and is the largest of its kind in Australia.

Drop Weight Impact Testing Facility

The Drop Weight Impact Testing Facility measures the behaviour of elements and sub-assemblies under high impact. The main frame consists of two long columns guiding a hammer which is tracked by a laser sensor. The weight of the hammer is adjustable up to 2000kgs.

The facility provides an advanced platform for researchers, industry and students to pursue innovation in design and construction, in the areas of protective structures design, impact cratering, excavation and mining, blasting and fragmentation, risk management, and more.


The National Drop Weight Impact Testing facility’s hammer has the capacity to create an impact energy of up to 200,000 J and impact velocity of up to 18m/s. The impact force is measured by the load cells embedded in the hammer. Impact loading can be applied to specimens with a width of up to 1m and length of up to 2m. All strains/displacements recorded within each test is captured by an optical non-contact 3D photogrammetry system.


This facility has the capacity to assess the structural safety of high-risk infrastructure including railway networks, tunnels and bridges, buildings and construction materials, as well as road safety barriers and protective equipment subject to impact loading.

In collaboration with: Monash University, UNSW, Swinburne, QUT, University of Wollongong Australia, The University of Melbourne and UTS.
