Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Integrates a heavy-duty two-stage rotary screw compressor delivering an upgraded 15 m³/min at 18 bar (261 psi). Powered by a single 162 kW Yuchai 6-cylinder diesel engine, it provides higher air flushing velocity for ⌀90–127 mm holes while cutting total fuel consumption by up to 30%.
Upgraded hydraulic rotation gearbox delivers 2,000 N·m maximum torque at 0–120 rpm, paired with 25,000 N push-pull force. Provides robust anti-jamming torque to penetrate through fractured rock and complex geological formations (f=6–20).
Features dual-speed crawler travel (2.5 km/h low-speed working mode / 4.0 km/h high-speed relocation mode) with 330 mm ground clearance and ±10° hydraulic frame levelling, allowing rapid repositioning between quarry benches and 25° hill climbing.
Equipped with an onboard dry cyclonic laminar flow dust extraction system. Captures cuttings and respirable silica dust directly at the borehole collar, providing clear operator visibility and complying with green quarry standards.

A: The KT6C upgrades the onboard two-stage compressor capacity to 15 m³/min @ 18 bar (versus 12 m³/min @ 15 bar on the KT5C), increases rotary torque to 2,000 N·m (versus 1,680 N·m), expands hole diameter to 127 mm, and features dual-speed tramming (2.5 / 4.0 km/h) for faster relocation.
A: No. The KT6C is completely autonomous. The 162 kW Yuchai diesel engine powers the hydraulic drilling and positioning systems while directly driving the onboard 18-bar two-stage screw air compressor, operating with zero trailing hoses.
