AAdroit 412 is designed to perform wet and dry shotcrete application fast and ef ciently on rough terrains, at shaft applications, in stairs tunnels and the parts of underground mines that are dif cult to access and on highly inclined slopes where truck-mounted, 4×4 robot and stationary shotcrete pumps and concrete mixers cannot reach. Also, it is an ideal solution for ground applications and earthquake retro tting works. Adroit 412 can make 360° shotcreting, up to 16 m diameter shaft applications. Thanks to its towing crane with rope, it can be easily positioned on the application sites where other vehicles cannot reach.
