While it was expensive, those involved realised they had little option but to go underground to protect the environmentally sensitive Mullum Mullum Valley, an untouched area of wood and bushland in Melbourne. EastLink, the 39km toll road project on the easter

Sandvik is rolling out a range of sophisticated tunnelling jumbo drilling rigs, equipped with advanced automation features. The new DTi models feature wide coverage and powerful HX5T drifters that enable them to carry out large and small and tunnelling jobs. To optimise operation, the four machines can use Sandvik's latest iSURE software, which allows blasting operations to be designed on a PC and then downloaded onto the rigs using conventional USB memory sticks: this allows full automation of the face dri

Liebherr's new LB Series rotary drilling rigs are designed for operations using Kelly equipment, continuous flight augers and double rotary heads. These can be used in an array of ground stabilisation applications for construction projects and complement the firm's proven LRB range of combined piling and drilling machines. There are four models in the new LB range, with operating weights from 68.4-113.5tonnes and these are capable of drilling diameters from 1.2-2.5m and to depths from 35-70m using Kelly equ

A frequent problem for fleet operators is created by drivers interfering with the CCTV monitors in their cabs, making them unable to show reversing or other camera images. Brigade Electronics has responded by developing a new tamper-proof model, and this means the top-of-the-range BE-870FM's software upgrade allows fleet operators to disable the driver's ability to adjust monitor settings, by locking the control panel, while retaining necessary functionality. The flat-screen colour monitor has single, sp
