| 摘要： | Drum cutter attachments from Erkat, now part of Epiroc, have been used successfully on a tunnelling project in New Zealand. The five transverse drum cutters have been used on the project in Auckland. Supplied by Erkat distributor Digga NZ, the Erkat attachments are being used for a 3.45km tunnel that features twin tubes, now under construction up to 42m below the city centre. The two larger Erkat drum cutters are currently in operation excavating the tunnel opening. The smaller attachments will be used for wall profiling, excavating service tunnels and other tasks. |
