Ground Support Equipment
AssemblyThe equipment that installs rock support as the tunnel advances. Roof drills, a ring beam erector, a mesh erector and a probe drill work in the L1 zone directly behind the roof shield, and shotcrete is sprayed from the backup in the L2 zone. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
