Product Details
Performance Features
1.Transportation is available without disassembling drill rods, which reduces logistics costs and improves transfer efficiency. The lower chassis is equipped with telescopic tracks, with a fully retracted width of 2850mm and a fully extended width of 3900mm. It features excellent trafficability and flexible construction in narrow sites.
2.Equipped with a high-power Dongfeng Cummins engine, it complies with China’s National Stage III emission standards, and is economical, efficient, eco-friendly and stable in operation.
3.The self-developed power head benefits from 20 years of technical accumulation, with a maximum speed of 30 r/min. It presents high torque, reliable performance and stable quality.
4.The hydraulic system adopts advanced international design and is specially optimized for rotary drilling rigs. Core components including main pump, power head motor, main valve, auxiliary valve, balance valve, travel system, slewing system and pilot handles are all well-known domestic and international brands. The auxiliary system adopts a load-sensing system to realize on-demand flow distribution.
5.All key components of the electric control system, such as display, controller, inclination sensor and depth measuring proximity switch, adopt high-end original parts from famous brands at home and abroad. The control box is equipped with high-reliability aviation connectors, making it a dedicated high-quality product for domestic construction machinery.
6.The main and auxiliary winches are installed on the mast for convenient observation of steel wire rope layout. Adopting double-broken-line drum structure, it avoids rope biting during multi-layer winding, reduces rope wear effectively and greatly extends the service life of steel wire ropes.
