The newest line of small-medium sized drilling rigs, especially designed by MAIT, have been developed on MAIT’s machine base for maximum purpose-built drilling performance and for lowering the cost. The crawlers are expandable and the cabin is large and comfortable. The HR 45 is one of the models of the new line, and can work in bored piles or CFA version. It converts rapidly between the two applications. The machine is transported completely mounted.
