The Terex CR652RX spreading auger design uses two outboard engines. Five-ft-long auger sections deliver independently adjustable material. Auger shafts are lined to reduce wear and have a 12-in. diam. A variable-pitch design—10 in. at the front of the hopper to 12 in. just before the feed tunnel—channels material from the hopper to the augers. It has more than 900 tph and is powered by a 260-hp engine. Hopper capacity of the CR652RX is 16.7 tons, which can be extended to 27 tons. Depending on screed model, paving widths reach 30 ft at depths up to 12 in.
