Drum centrifuges
Offering several advantages over the more traditional beam centrifuges, Broadbent G-Max drum centrifuges are developed from the innovative design patented by Emeritus Professor Andrew Schofield FREng, FRS, of Cambridge University Schofield Centre.
In addition, Broadbent G-Max has developed the modular centrifuge – the world’s first single-platform, multi-test environment incorporating an interchangeable beam and drum centrifuge. We designed this revolutionary centrifuge specifically to provide a complete test environment for civil engineering researchers. Visit our Special Projects section for more details.
- lower civil engineering costs
- conduct multiple tests on a single sample
- change tools, sensors etc whilst sample is ‘in flight’
- model high 1G sample lengths, up to 2,500m
- lower power consumption
- virtual beam mode gives wider application options
- ‘in flight’ advanced manipulation of tool position
- more compact than beam centrifuges
- safety shield feature
- large sample footprint
- current designs – up to 400 times gravity
- free-standing
- rotating parts housed within robust casing
- aerodynamically efficient
- engineering support services available worldwide
