The Putzmeister Wetkret 4 is a robust and compact concrete pump designed for underground mining applications. With its heavy-duty chassis and crab-mode, it is ideal for maneuvering through tight spaces and mining galleries, offering a wide range of movement. Equipped with a concrete flow of 20 m³/h, it enhances productivity while ensuring consistent and homogeneous shotcrete application, reducing rebound and ensuring the required layer thickness. The Wetkret 4's maximum vertical reach of 8.5 m allows for flexible spraying in confined areas. Its automatic synchronization of additive dosage with concrete flow guarantees precise application and spraying quality. Additionally, easy handling is achieved through a dual cable and wireless remote control. With optimized weight distribution and easy access to maintenance points, the Wetkret 4 is designed for efficiency and convenience in demanding underground environments.
