Terex's RS446C reclaimer/stabiliser is said to offer significant efficiency savings over its nearest rivals in the 373kW power class while offering similar working output. The machine is said to save up to 30% on fuel costs. The maximum cutting depth on the new model is now 508mm, an increase of 25% from the firm's earlier model. The RS446C now features a two-stage engine drive and three-speed cutter transmission. The new drive maximises break-out forces and delivers a production rate of up to 47m/min, whil
High performance reclaiming and stabilisation duties can be handled by Terex's new RS446C model.
Contractors can now choose between 2271litres/min water only or water/emulsion additive systems for reclamation and stabilisation applications. The housing for the 2.44m wide cutter features a front door that opens twice as far as previous designs, which aids in product grading and sizing when operating in either the up-cut or down-cut directions.
The RS446C has a simplified frame design and features a new rear axle layout that boosts performance. Kingpins replace spindles at the wheels to allow the tyres to pivot closer to the frame, reducing the turning radius to 4.3m. This is nearly 50% tighter than previous models and increases manoeuvrability considerably. The operator can select four wheel steer, crab steer and either front or rear steer only options. Meanwhile four wheel drive allows the machine to operate reliably in challenging applications.
Located at the rear of the machine, the service area makes maintenance a more straightforward operation. This is equipped with a fold-up ladder, single-point access for fuelling and hydraulic fluid and allows access to the central lubrication system. Service panels in the frame offer greater access to hydraulic pumps and the drive system, while sand can be used in the rear counterweight chamber. The RS446C has a full-width, high-visibility cab with a sliding operator station that allows a good view to either side of the machine. Weighing in at 25tonnes, the machine has a transport height with cab and ROPS of 3.5m and a width of 3.2m.
