27, 2012, Oklahoma City, Okla. – The new Terex RS446D Reclaimer/Stabilizer
features a powerful 415 hp (309 kW) diesel engine that meets stringent Tier 4i
and Stage IIIB emissions standards. The new engine configuration improves fuel
efficiency over previous RS446 models and reduces noise levels to the operator’s
ear by 5 dBA for operator comfort. The machine’s two-stage engine drive and three-speed
cutter transmission that increases break-out force helps to save up to 30 percent
on fuel costs over similar sized machines.   

Incorporated
into the new design, a shorter engine cowling improves the operator’s line of sight
to the front of the machine. The new hydraulically tilting hood offers easy
access to engine components for quick servicing. The engine configuration in
the RS446D positions all engine components, including the oil filter, air
filter, fuel filter and battery, in a single service center accessed from
ground level, reducing maintenance time for the service technician.

The RS446D
boasts a standard full-width cab with an upgraded heating and cooling system to
improve operator comfort. A second evaporator and blower significantly increase
airflow to the eight adjustable HVAC system outlets, so the cab remains cool
even in the most extreme summer temperatures. Tinted cab glass also helps to
reduce temperatures inside the cab. A unique sliding operator station improves
visibility to both sides of the reclaimer/stabilizer.

Compared to the
C Series, the RS446D increases torque to the mechanical cutter drive system.
This, combined with three rotor speed selections, allows the operator to more
effectively match cutter speed to the application, improving reclaiming and
stabilizing efficiency. The RS446D offers
a 96-in (243.8-cm) cutting width and a maximum 20-in (50.8-cm) cutting depth,
depending on soil conditions.

A redesigned water/emulsion system moves major components from the side
of the machine to underneath the hood. With this new design, the system’s pump
and plumbing are now in a more concealed location, reducing the chance for
damage to increase uptime. The system’s fill-point remains easily accessed on
the machine’s outside, but it features better protection for enhanced
durability. To improve machine versatility, the RS446D offers both water-only
and water/emulsion systems.

The RS446D boasts
some of the same designs as its predecessor that improves machine reliability
and servicing ease in the field. A simplified frame design significantly
reduces the number of frame components, boosting machine uptime. Its two-piece,
bolt-together frame offers unobstructed access to the engine. Located at the
rear of the machine, the RS446D’s service center provides single-point access
for fueling and maintenance of hydraulic fluid and central lube systems.
Conveniently located service access panels in the frame offer greater access to
hydraulic pumps and the drive system.

This reclaimer/stabilizer features a true rear axle design for efficient
performance. Kingpins replace spindles at the wheels to allow the tires to
pivot close to the frame, offering a tight 14-ft (4.3-m) turning radius.  Four steering modes – crab, coordinated, front
only and rear only – improve machine maneuverability and flexibility at the job
site

The Terex
RS446D Reclaimer/Stabilizer has a transport weight of 59,380-lb (26,934-kg) with
standard cab and water system. The machine’s transport height with cab and ROPS
is 11-ft, 6-in (3.5-m) and width is 10-ft, 4-in (3.2-m).
