XR460E

XCMG XR460E rotary drilling rig performance characteristics: 1. The telescopic crawler chassis with swing legs is adopted to meet the stability of large-tonnage drilling rigs and the convenience of disassembly and transportation. It is equipped with large-diameter slewing bearings and has stronger anti-overturning ability; 2. The power head adopts vertical pin connection type power box body and bracket, which has high reliability and convenient disassembly and assembly; 3. The power head has normal mode, rock entry mode, medium speed rock entry mode and energy saving mode. Users can choose corresponding modes according to different geological conditions, which improves construction efficiency and reduces fuel consumption; 4, the main hoist using single row rope technology, wire rope life than multi-layer rope 2 to 4 times longer, the use of lower cost; 5. The hydraulic main and auxiliary systems adopt load-sensitive control technology, which has fast response and good handling performance. It adopts a double overhead heat dissipation system, which intelligently adjusts the heat dissipation capacity according to the temperature, with strong heat dissipation capacity, energy saving and noise reduction; 6. Equipped with Cummins 15L electronically controlled turbocharged engine, strong power, low fuel consumption, convenient and quick service, decentralized independent heat dissipation system, strong heat dissipation capacity and low noise.
