Just like its bigger brother “Jocker,” it is used for milling operations on the concrete vaults of tunnels. This equipment consists of a milling head mounted on a telescopic arm, which in turn is mounted on a slewing ring that allows continuous 360-degree rotation, enabling work on inclined or upward surfaces. It is suitable for application on 25 to 30-ton excavators, and thanks to a quick-attach system with hydraulic pins, it can be quickly disassembled to return the machine to excavation configuration.
