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 the heavy-duty DTH drilling system and an onboard rotary screw compressor (12 m³/min @ 15 bar) onto a single crawler chassis. Powered by a 176 kW (240 HP) Yuchai engine via dual-terminal output (flywheel drives the compressor while the PTO powers hydraulic circuits), eliminating auxiliary compressor towing and cutting fuel costs by up to 30%.
Features a fully enclosed, certified ROPS & FOPS safety cab with standard heating and cooling air conditioning, an adjustable ergonomic operator seat, radio entertainment, and indoor noise levels below 85 dB(A). Responsive hydraulic pilot joysticks provide effortless, fatigue-free control over all drilling and tramming maneuvers.
Equipped with an automated mechanical pipe carousel (7+1 storage for Φ64×3000 mm rods), floating slide plate, and automatic thread lubrication. Intelligent electro-hydraulic anti-jamming system continuously monitors penetration pressure to prevent tool sticking, enabling safe, single-operator drilling down to 24 meters.

A: The ZT5 features a certified ROPS & FOPS enclosed cabin with standard heating/cooling air conditioning, low indoor noise (<85 dB), and hydraulic pilot joystick controls. Combined with an onboard 15-bar screw compressor and a 7+1 automatic rod changer, it delivers superior operator safety, dust-free comfort, and high single-operator productivity.
A: When drilling through fractured or sheared rock formations, rotation torque and feed pressure spikes are detected instantly by hydraulic pilot sensors. The system automatically reduces feed force, retracts slightly, or increases flushing to clear cuttings, preventing drill string seizure and protecting the 3" DTH hammer.
