When performing an overcut due to restrictions on the bend angle due to the In some cases, it is often necessary to change the excavation diameter of the cutter head 2. In this way, when it is desired to expand or reduce the diameter of the excavation by a relatively small dimension similar to the thickness of the shield plate, there is no suitable method in the past, and when this must be done, a hydraulic cylinder is used. This meant that they had no choice but to adopt large-scale devices such as link mechanisms that had previously been used.
