KS Series 300-400m Crawler Water Well Drilling Rigs – Powerful Performance for Medium-Deep Projects
The KS Series 300-400m crawler water well drilling rigs are engineered for contractors requiring enhanced power, efficiency, and versatility in medium-depth applications. This series includes four models (KS300A, KS300B, KS350, KS400) that combine robust Yuchai diesel power with advanced hydraulic systems to deliver outstanding performance in diverse geological conditions.
Key Features:
Powerful Yuchai Engines: All models are equipped with reliable Yuchai turbocharged diesel engines (85-92kW) ensuring strong power output and excellent fuel economy.
Long Feed Stroke Options: KS300B, KS350, and KS400 feature 6.6 meters one-time feed stroke, significantly reducing pipe changing time and boosting drilling efficiency.
High Torque Range: Rotary torque ranges from 5700N·m up to 9000N·m, with adjustable speeds for optimal penetration in various formations.
Dual-System Ready: All models support optional air compressor and mud pump systems for maximum operational flexibility.
Heavy-Duty Excavator Chassis: Rugged construction with wide track plates ensures stability and long service life.
Enhanced Safety: Boom limit devices protect lifting cylinders during operation.
Model Highlights:
KS300A (6.8 tons): Compact design with 3.3m feed stroke, 5700-7500N·m torque, ideal for confined sites.
KS300B (8 tons): Long stroke (6.6m) with 18 tons lifting force, perfect for maximizing efficiency.
KS350 (8.6 tons): Features clutch and auxiliary radiator for high-altitude/cold climate operations.
KS400 (9.2 tons): Independent dual cooling system for extended component life, 6500-9000N·m torque.
With 15-35m/h penetration efficiency and 30° climbing ability, these rigs are ideal for water wells, geothermal drilling, and foundation construction.
