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
Powered by dual hydraulic rotation motors delivering up to 5,000 N·m maximum torque at 0–90 rpm. Ensures aggressive penetration through hard, fractured rock formations (f=6–20) with large ⌀90–152 mm hole diameters.
Equipped with a Yuchai four-cylinder diesel engine (58 kW on KG430; upgraded 73 kW on KG430H), satisfying national Tier 3 / Stage III off-road emissions standards with superior torque backup and fuel economy.
Expanded feed cylinder and heavy-duty roller chain generate 40 kN lifting force. High-pressure plunger piston tramming motors, engineering track system, and ±10° track leveling enable smooth traversal across 30° slopes.
The KG430H configuration features a standard QZA-120 dry cyclone dust collector (12 filter elements, upgradable to QZA-140 with 16 elements for holes >130 mm), significantly reducing airborne dust for green quarry compliance.
