A new tunnel formwork system from Pilosio reduces the time needed for assembly. Made from standard components, this can be used for a wide range of geometries.
The Freeway Tunnel Ventilation On-Demand System for Melbourne’s EastLink project picked up the top Industry Award category at the recent 9th ITS Australia National Awards
Traditional tunnel ventilation systems are inefficient. Fans operate at fixed speed in manual mode or with individual fans programmed to switch on and off at preset times to ensure zero portal emissions with all emissions dispersed via ventilation stacks.
EastLink’s new ventilation on demand – VoD - system matches variable speed fan
New technology broadens Sandvik's offering for crushing and screening. Mike Woof reports Sandvik is making a series of upgrades to its crushing and screening line in jaw and cone crushers as well as wear parts, and these should suit an array of applications ranging from small recycling operations up to large quarry sites. At the more versatile end of the range is the new CJ208 jaw crusher, the latest addition to the CJ200 series jaw crusher line-up. This crusher is the smallest of the CJ200 Series and offer
New developments in tunnelling technologies offer contractors greater efficiencies when constructing new bores. Tunnel boring machines (TBMs) are widely being used in major projects such as the Brenner Base Tunnel in the Austrian Alps. Full face TBMs are highly sophisticated machines featuring a rotating drilling head, which removes the material, and, depending on the type of construction, secures the excavated tunnel with shotcrete, rock bolts and wire mesh or prefabricated segments of reinforced concrete.
