Putzmeister SPM 4210 WETKRET Series features a reinforced spraying arm that provides a vertical spraying reach of nearly 33 feet, and the maximum concrete output of the double-piston pump mounted on the equipment is nearly 26 cubic yards per hour. The new model’s proportional remote control, says the company, allows for easy operation of the spraying arm, regulation of concrete output, and adjustment of the dosing pump. The SPM 4210’s axles and reinforced turning system are designed to allow negotiate difficult working conditions in mining applications. The new model is available in three versions designed to meet different job site requirements. The electrically operated, standard version includes an on-board air compressor. The Dual Drive version has a dual operating system, allowing all of its components to be operated either by diesel or electrically. This version also is available with an on-board air compressor. The Rotor version works with a rotor pump, which allows the equipment to be used for both the wet and dry spraying process. It also includes an on-board air compressor.
