AGGREGATES MANAGER October 2014
The Volvo EC250E and EC300E crawler excavators deliver a
5-percent improvement in fuel efficiency compared to past models.
The gain is attributed not only to the Tier 4 Final Volvo engine, but
also to a range of features that optimize flow and minimize pres-
sure losses in the hydraulic system, including ECO mode, which
automatically reduces fuel consumption without any loss of per-
formance in most operating conditions. In addition, the excavators
can be equipped with automatic idling and auto-engine shut down
systems as optional equipment. All operator interfaces — including
joysticks, keypad, and LCD monitor — have been ergonomically
designed and positioned for comfort and efficiency.

The Atlas Copco SmartROC T35 and SmartROC T40 are the first
surface drill rigs from the manufacturer to offer the option of radio
remote control operations by upgrading either rig with a SmartROC
radio remote control kit. The T35, for hole diameters of 2 1/2 to 4
1/2 inches, and the T40, for hole diameters of 3 to 4 1/2 inches, drill
to a maximum depth of 92 feet. The rigs are designed with a low cen-
ter of gravity and a high ground clearance so they can operate safely
on rough terrain. The T35 is fitted with the 27-horsepower Cop
1840 rock drill, while the T40 comes with a 33.5-horsepower Cop
2560 rock drill. A boom reach of 25 feet in height for horizontal drill-
ing and 18 feet forward for vertical drilling offers flexible operations.
