Abstract

PURPOSE: To enable excavation of the entire facing of the cave by increasing the excavating force with a stable vehicle body while ensuring a continuous excavation of the cave efficiently in the axial direction of the cave regardless of the angle thereof.
CONSTITUTION: The lift frame 4 is provided on the body of the excavator equipped with the crawler type travelling device 2 and the excavating equipment 12 in such a manner as to move vertically. The lift frame 4 is provided foldably with the body retaining device 22 comprising the device 26 adapted to roll in contact with the ceiling of the cave and the cylinder 25 for supporting the strut arm 24. In addition, the elevating frame 6 is provided on the lift frame 4 in such a manner as to rotate from the horizontal to vertical state. The slewing frame 8 equipped on the excavating equipment 12 is provided on the elevating frame 6 to slew it. The excavator thus arranged is used to excavate the desired cave.
