Tunnelling Excavator

Tunnelling Excavator has been developed in Korea to suit various geologic conditions. Various tools such as special bucket, ripper tooth, hydraulic breaker and twin head cutter can be very simply and quickly attached depending on the tunnelling works and varying geologies of soft soil and rocks.

Advancing of tunnel excavation, scaling and profiling can be most effectively executed by proper usages of such tools. The robust boom consists of special designed multi-joints and rotate 45 degree each side to enable very accurate and excellent tunnelling works. Our engineers will cooperate with you to find the ideal solution for your project and specific requirement.
