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
Engineered specifically for large-diameter drilling (⌀115–203 mm) in ground-mounted solar photovoltaic (PV) pile foundations. Easily penetrates hard rock, limestone, and boulder layers to accelerate solar farm construction.
Features a high-reduction gearbox driven by dual hydraulic motors delivering over 3,500 N·m torque at 0–110 rpm. Powers 4", 5", and 6" DTH hammers without stalling in fractured or abrasive ground (f=6–20).
Propulsion is driven by a hydraulic oil cylinder and 20A roller chain (3,475 mm feed stroke, 40 kN lifting force). The upper, middle, and lower sections feature high wear-resistant nylon plates to extend mast life and reduce operational maintenance.
The upgraded hydraulic system uses heavy cast-iron gear pumps with large displacement. Combined with ±10° track leveling and enhanced plunger travel motors, it maneuvers safely across 30° mountain solar slopes.

Diesel Engine Portable Screw Air Compressor:
Note: Air compressor selection is subject to hole diameter and air hose length.
A: Solar mount foundations require fast drilling in rough mountainous soils with hidden rocks. The KG200GF features 3,500 N·m dual-motor torque, 40 kN lifting force, and ±10° track leveling, allowing it to drill ⌀115–203 mm pile holes rapidly on uneven hillsides where conventional rigs struggle.
A: For solar pile holes using 4" to 6" DTH hammers, the Kaishan KSGF220-19 (22 m³/min @ 1.9 MPa) or KSCY310/22 (22 m³/min @ 2.2 MPa) diesel screw compressors provide optimal airflow and pressure to clear cuttings efficiently.
