Liebherr Concrete Technology has announced North American market availability of the RIV 2.5 D Ring-Pan mixer, equipped with separate motors driving the main shaft and mixing arms plus agitator rotors. Shaft and agitator rotational speeds can be adjusted to specific concrete mix designs, and set at different rates for dry or wet loads and discharge cycles. Variable mixing control features make the model especially suited to high performance concrete.

With hourly output up to 115 cubic meters, the RIV 2.5 D has seen multiple installations in Europe since its bauma 2016 debut in Munich. LCT spotlighted the mixer at World of Concrete 2018 in Las Vegas, and will also feature the model at the National Precast Concrete Association’s The Precast Show, February 22-23 in Denver. —
