The concrete pump Sermac 5RZ51 has been designed to satisfy the latest market requirements between total weight and total length of equipment, furthermore concrete pumping performance, without the use of composite materials. The Sermac 5RZ51 is able to achieve record-breaking performance of weight, thanks to the extraordinary design of our center S-DESIGN. The 5RZ51 thanks to the distributor boom in 5 sections with "RZ" is ideal application in the yards of medium-large areas such as pumping at height as elevated roads and bridges or pumping in length as slabs, foundations and walls. The length of the boom over 50 m and the pipeline Ø 125 mm make the 5RZ51 ideal for jobs which require larger flow of concrete and allows the positioning of the pump also the most difficult sites thanks to front stabilization "X" and rear outriggers. The 5RZ51 also combines a perfect assembly on truck 4 (or 5) axles with wheelbase 5.750 - 6.350 mm. Total mass on ground < 37 t and total length < 12 m. The pumping groups at open hydraulic circuit have high reliability from 150 m³/h to 194 m³/h concrete output and pressures till to 85 bar.
