TOP ROLLOUTS
VOLVO
Fuel-efficient excavator
The Volvo EC250E crawler excavator delivers 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 pressure losses in the hydraulic system, including ECO mode, which
automatically reduces fuel consumption without any loss of performance 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 ergo-
nomically designed and positioned for comfort and efficiency.

VOLVO
High ground clearance artic
Volvo's A40G articulated haul truck features a new turbocharged six-cylin-
der Volvo engine that meets Tier 4 Final emission regulations. The drive-
train and inline dropbox are designed for high ground clearance, while the
drivetrain delivers high rimpull, lowers fuel consumption, and provides
reliability in heavy-duty applications. Oil-cooled wet multiple disc brakes
are said to reduce maintenance costs and increase uptime, even on muddy
or dusty sites. A retardation system controls downhill haul speeds using
wheel brakes and the engine brake. Automatic traction control and dif-
ferential locks are standard, while an onboard weighing system allows the
equipment operator to optimize payload. The machines are also fitted
with CareTrack, Volvo's telematics system.

TEREX WASHING SYSTEMS
Modular scrubbing system
Terex Washing System's AggreScrub 150 is designed to separate stubborn
clay material that cannot be removed by rinsing or screening alone. The
system can work as a standalone unit or in conjunction with Terex's Ag-
greSand plant. The modular plant includes a web frame chassis design that
supports a scrubbing hull, a 6- by 2-foot trash dewatering screen, a 12- by
5-foot two-deck rinsing and sizing screen, and has an integrated sump and
pump. Galvanized walkways are said to provide unprecedented levels of
access to all areas of the plant. The control system used on the AggreSand
plant has been adapted for this plant. Radio control of all main functions is
available as an option, as well as remote telemetry, which enables data to be
sent to the plant owner remotely, through email or SMS alerts.
