Italian firm 1141 SIMEX has produced a new TF 800/V rotary cutter for tunnel excavation applications.

Two of the new rotary cutters were used to help construct the key Varzo Tunnel link in Italy, close to the border with Switzerland.

Attached to a pair of 2300 Komatsu PC138 US short-radius excavators, and featuring a modified boom and special bracket, the rotary cutters were used to cut around 20cm deep and 40cm wide into the crown of the tunnel in order to create the inserts for two-hinged steel ribs every 1.75m, anchored to ties with a C-shaped fastening element (totalling 44 elements).

The cutters, deployed by Italian contractor Ceprini Costruzioni (CC), were equipped with drums measuring a width of 40cm and diameter of 110cm, and fitted with 144 Betek VC 33 bits with a 2.2cm bit holder.  Both cutters were said to have proven productive and reliable and were operated without interruption for 164 hours each.
