The SERMAC 6RZ65-L concrete pump is designed with a versatile 6 section“RZ” fold boom type made in high quality stainless steel S900. The 6RZ65-L pump is ideal for large applications, such as pumping at height on elevated roads and bridges or pumping at length in slabs, foundations and walls. A boom length of over 64 m and Ø 125mm pipeline makes the 6RZ65-L perfect for jobs which require a larger flow of concrete. The L-type front outriggers and swing-out type rear outriggers provide great stability in every pumping phase. Concrete pipeline supply in Twin-Wall straight pipes with extremely abrasion-resistant hardened inner liner. Bends made in Twin-Wall steel with chromium carbide inner. The 6RZ65-L combines a perfect assembly on a 5 axle truck with a wheelbase of 6.350 mm. Excellent ratio between the total weight and 6-stage boom to achieve maximum efficiency: < 52 t (114640 lb) on a 5 axle vehicle. The pumping groups S8 and G9 with open circuit hydraulic system offers reliability and high performance; up to 195 m³/h concrete output at pressures of up to 85 bar: maximum efficiency and minimum wear.
