Claims

[Scope of utility model registration request]

An annular body is attached to the main body of the shield excavator so as to be able to rotate about its horizontal axis, an erector arm is attached to the annular body so as to be movable in the radial direction, and an erector arm is attached to the erecta arm in a longitudinal direction along the horizontal axis. For segments, a slide arm is attached to allow movement, a grip support is attached to the slide arm to allow yawing, and the grip support is attached to the same grip support to enable pitching and rolling via multiple hydraulic cylinders. An erector device for assembling segments of a shield excavator, characterized by comprising a gripper.
