- Operator cabin
- Hydraulic system
Working Principle
The Kaishan KT12 operates on the principle of down-the-hole (DTH) drilling. A pneumatic hammer is positioned directly behind the drill bit, striking the rock with high-frequency impacts while the rotary head rotates the drill string. Compressed air, supplied by an onboard or external compressor, drives the hammer and also flushes cuttings out of the hole. The crawler chassis allows the rig to move easily between holes, and the hydraulic feed system applies optimal force for efficient penetration. The operator controls all functions from a centralized panel, ensuring precise and safe operation. This method is highly effective in hard rock formations, delivering straight holes and high productivity.
