HAMMER has an hammer-mil powered by two hydraulic motors right at the end of the main rotors shaft. The mil is fed by a hopper and a chain conveyor with adjustable speed that allows to dose the quantity of the material to be treated for the best performance. The strong undercarriage makes it suitable for working on steep slopes (<70%). All the functions are radio controlled to allow the not necessarily skilled operator to safely keep control of the work he is doing.
HAMMER offers the advantage of producing enough fine material to complete the protection of the pipe, in rocky areas too. The outlet grills are adjustable to obtain the grain size required by the project specification.
