The sizes of different models of turntables are suitable for 2.2mx2.2m-2.7mx2.7m / 2.5mx2.5m-3.0mx3.0m
Tunnel Pneumatic DTH Drilling Rig This compact underground drilling machine is specifically engineered for
tunnel excavation and subterranean boring operations, utilizing compressed-air-powered DTH (Down-The-Hole)hammer technology for efficient rock fragmentation in confined spaces.
The rig features a low-profile design with 360° omnidirectional drilling capability, achieving precision boreholes
(Φ50-80mm) through granite and hard strata with minimal vibration transmission.
