<p>Tunnelling machine with loading-out facility is intended for tube drivages and consists of a main boom which is fitted with a rotary cutter drum and a converyor to carry spoil along the boom, the boom pivoted on a support frame which is carried on a loading-out conveyor so as to move in the direction of advance. The support frame (15, 16) for the main tooling boom (13) can itself slide along on the loading-out conveyor (17) which descends in the advance direction. Preferably the scraper chain conveyor serving as loader-out (17) rises steadily from its face end to the rear delivery end (23), though it can also be adjustable in angle. In this case, the conveyor (17) should be supported on the floor frame (18) at one end via a joint (25) and otherwise by means of a support (26) at a distance from the joint.</p> |
