2403 Sandvik Construction is launching its new Alpha 330 drilling tool system for drilling and tunnelling.

It has been developed with special features that control power and ensure this power is transmitted into the rock as efficiently, accurately and economically as possible.

The company says that in tests, in varying rock conditions, the new design has been proven to deliver a 30-80% increase in rod life; provide more accurate collaring and straighter blast-holes, thereby delivering greater advancement and improved profile control. This enables projects to be completed more rapidly, as well as reducing the overall cost of drilling and tunnelling, says Sandvik.

The Sandvik Alpha 330 has been designed and dimensionally optimised to replace the R32 connections, which until now has been the dominant Ø 45mm system.

“A key development of this advanced new system sees the drill string rod/bit connection featuring an entirely new thread design. Furthermore the Alpha 330 possesses a shorter thread on the hexagonal rods in the tool system resulting in a rigid, integrated power-pack drill string, which possesses superior resistance to bending stresses, thereby securing perfect energy transfer,” says Sandvik.

“As part of the manufacturing process more steel has been used for higher fatigue strength, which further helps ensure exact collaring and straighter holes, as well as delivering a 30-80% increase in rod life.”

Customer feedback on the Sandvik Alpha 330 tool system in global tunnelling projects is said to have shown rod life has been extended by at least 30% and longer shank adaptor and coupling lifespans.

    January 30, 2013
    Netherlands-based D-TEC has developed a novel vacuum tank trailer system for applications such as bentonite extraction during sample boring. An innovative steering system is said to allow the D-TEC vacuum tanktrailer to manoeuvre easily on sites where there is little space. This design also reduces tyre scrubbing and allows greater tyre life, cutting running costs over the long term. The tank trailer offers greater load capacity than previously available designs according to the firm, due to its low weight,

  • Liebherr’s HS8300HD crawler uses hybrid drive to reduce fuel consumption
    January 6, 2017
    Liebherr has developed a hybrid drive system for its HS8300HD heavy duty cycle crawler crane. The 350 tonne machine generates electrical power from its hydraulic free-fall winches, which offer up to 50 tonnes of line pull. Under this Pactronic system surplus energy is stored in a hydraulic accumulator and regenerated to assist the engine, reducing fuel consumption. This reuse of energy also cuts emissions from the machine.
