详细说明
KAISHAN surface DTH drill rigs, equipped with powerful down-the-hole hammers, are designed for high-capacity rock drilling in surface mines. They are completely self-contained, with onboard compressors and efficient dust suppression. They are highly productive and very reliable, with low life-cycle costs.
Air HydraulicKT7 is our smallest crawler mounted, down the hole pneumatic drill rig, and is ideal for work in confined areas. It is a fully mechanized, self propelled, heavy duty drill. It is a simple one-man operated rig, easy to operate and easy to maintain. The tramming controls are located beside the left track, and both tramming and drilling are powered by hydraulic motors.
