Meeting the big three

2011 Jul 29

Atlas Copco’s new crawler drill SmartROC T35 has scored points for the three most important demands in today’s surface drilling industry – low fuel consumption, increased productivity and high availability.

Low fuel consumption, increased productivity and high availability is the magic combination that drilling and blasting companies are looking for ? and the new SmartROC T35 meets all three expectations.
According to field tests in five countries, the new rig consumes as little as 10 to 15 liters of diesel per hour (under favorable conditions) and that is said to be half the fuel consumption of other comparable rigs on the market.
The SmartROC T35 also scores well for increased productivity and availability which further contribute to lower costs and better overall economy.
Rohléns Sprängtjänst AB of Sweden tested the rig for about three months in the Malmen quarry, north of Stockholm,  where it was used alongside three other Atlas Copco rigs, two SmartRig ROC D7C and a ROC D7.
?The rig was in operation for 40 hours a week during the test period and it worked really well,? reports the owner David Rohlén. ?There was a dramatic reduction in fuel consumption and a clear increase in productivity from the very first day.
?We have been using ROC D7 rigs since they were introduced in the 1990s. It has always been good, but the SmartROC T35 is a great improvement. A lot of things have been upgraded or changed and Atlas Copco has done it in the right way, especially when it comes to the design of the controls which makes this rig much easier to operate.?

New platform
The SmartROC T35, which features Atlas Copco?s rig control system (RCS), has new hydraulic systems, a Tier 4 engine which meets all current emissions regulations, coupled with a cabin that is said to be the most modern of its kind with the latest in ergonomics and comfort.
Rig Design Manager Jimmy Holler says: ?We started by developing a new platform for the control system at the end of 2006 and energy optimization was the goal. The result is that the operator can now adjust the capacity of the flushing air and the dust collector simply by pushing buttons. The RCS control system also makes sure that you get full hydraulic power at lower revs than previously and the engine is controlled in a way that makes it much more effective and efficient.?
Besides reducing fuel consumption by
50 percent, CO2 emissions are also reduced by 25?30 kg per engine hour, giving long-term sustainable productivity.
The SmartROC T35 and the larger T40 are designed for drilling and construction as well as quarrying. The T35 is equipped with a COP 2540 rock drill as standard with the COP 1840 as an option. It can tackle all types of rock in the hole range 64?115 mm.
