Roof Shield and Side Supports

Assembly

The shields around the cutterhead support. The roof shield and its fingers protect the work zone behind the face, the side supports and vertical support steady the front of the machine in the bore, and the dust shield closes off the cutting chamber. Retracting the shields shrinks the machine's diameter, which helps free it in squeezing rock. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
