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 a single 6-cylinder Cummins QSL8.9-C360-30 non-road diesel engine (264 kW at 2200 rpm), with a two-terminal output configuration that simultaneously drives the two-stage screw air compressor (20 m³/min at 22 bar) and a 5× gear-pump hydraulic transmission system for high-penetration 115–152 mm drilling.
Equipped with an automatic 6+1 rod-handling carousel for Φ76/Φ89×4000 mm drill pipes, a drilling-rod floating slide module, a drill-pipe lubrication module, and an automatic electro-hydraulic anti-jamming system to ensure uninterrupted 28 m deep-hole production in complex rock formations (f=6–20).
Features a certified FOPS & ROPS safety cab with standard heating/cooling air conditioning, indoor noise below 85 dB(A), hydraulic pilot controls for both traveling and drilling, a hydraulic dry dust collection system, and optional drilling angle and depth indication functions.

The Kaishan KD55 integrated surface DTH drilling rig is engineered for continuous, high-production bench blasting and pre-splitting operations across demanding surface sites:
The KD55 is a heavy-duty 17,500 kg cabin-equipped rig powered by a 264 kW Cummins QSL8.9-C360-30 engine with a FOPS & ROPS air-conditioned cab, hydraulic pilot controls, 40 kN propelling force, 100 kN traction, and a 6+1 rod changer for Φ76/Φ89×4000 mm rods (28 m depth), whereas the KD55ED is a 13,000 kg open-station rig using Φ76×3000 mm rods.
No. The KD55 integrates a built-in two-stage screw air compressor that delivers 20 m³/min at 22 bar, driven directly by the Cummins engine's two-terminal output alongside the 5× gear pump hydraulic system.
