Schwing RZ boom design combines the ´Roll and Fold´ boom with a Z-fold boom at the tip to offer 270 degree flexibility at the last boom section. The boom folding system also enables concreting work right up to the vehicle bumper. With an overall length of less than 12 m on a standard chassis this compact boom package does not extend beyond the machines outlet. With the 270-degree Z-fold section at the tip of the boom, operators have a myriad of options for placement while shooting concrete up to 42.3 meters vertically, and 38.1 meters horizontally. The S 43 SX has an unfolding height of 8.7 meters for those low overhead situations and a slewing range of 740 degrees to suit many job site requirements. Its pipeline is a full DN-125 mm diameter. The S43 SX front outriggers extend along an arc, do not have to be swiveled or telescoped and can fit into even the smallest gaps at the construction site thanks to their low height that saves space and time. The ´Generation 3-´ concrete pump is a low-maintenance, 164 m/hr unit that provides long, slow-stroking action. The all-hydraulic design utilises Schwing Big Rock Valve, promoting maximum filling efficiency of the material cylinders even with harsh mixes.
