The Putzmeister SPM 500 Wetkret Shotcrete Machine is designed for large tunneling, cavern, and slope stabilization projects, offering a vertical spraying reach of 17 meters and an output of up to 30 m³/h. Its advanced automatic additive dosage system ensures precise synchronization with the concrete pump, guaranteeing high spraying accuracy and quality. All operations are conveniently controlled via remote, including starting and stopping of the spraying sequence. The machine’s robust chassis with 4-wheel drive and crab-mode enhances maneuverability, even in challenging driving conditions. With a spraying arm that can unfold in tight spaces, the SPM 500 is highly versatile and efficient. It is available with either an integrated electric air compressor or a diesel engine for use in locations without electrical power. This shotcrete machine is ideal for large-scale projects requiring consistent and precise application.
