Abstract

PURPOSE: To improve operation efficiency in a tunnel by equipping a console that is suspended on a support stand rotatably with a swing arm, a control cylinder, a jib, and the like, and fitting an attachment that operates differently. CONSTITUTION: A console 16 that is suspended on an upper support stand 12 rotatably is equipped with a control cylinder 20 for tilting a rock arm 18 and a jib 21, a pivoting cylinder 25 of an attachment, and the like. Then, an excavating tool 26 with a drill and a shovel is fitted to the tip of a device, and each hydraulic cylinder is operated for excavation and raking. Also, depending on the details of operation, the excavating tool 26 is removed and exchanged with an excavating shovel 48 for excavation. Also, by installing the upper support stand 12 on a driving vehicle, the entire device can be moved, thus performing operation efficiently even if space in the tunnel or the like is narrow.
