Abstract

PURPOSE: To achieve excavation of vertical shaft continuously right downward, to the entire bottom without dead angle and with a high efficiency.
CONSTITUTION: Plural sets of leg expanding device 2 are provided in such a manner as to be expansible or reducible with respect to the inner wall of the vertical shaft surrounding the body 1. On the other hand, the turning frame 6 is provided almost coaxially at the axial end of the body 1. The turning frame 6 is equipped with the excavating equipment comprising a boom 9, an arm 11, a backet 13 and the like. The vertical hole excavator thus arranged is used to excavate the vertical shaft as desired.
