Sunward SWDM420V Ultra-large multifunctional rotary drilling rig

◆Heavy duty chassis

PCTPatented chassis，Greater telescoping range，Transportation is not too wide，Work is more stable。

◆Efficient rock entry

Adopt rock-entry strengthening design，Combine high-strength drilling mast，Telescopic chassis with stable large triangular luffing mechanism and large and small telescopic beam structures，The force is uniform，The shaking of the whole machine is small，Rock entry is more efficient。

◆Economical and energy-saving

Application of Load Sensing Technology in Hydraulic System，Overlapping total power control and limit power control technique，Different rotating speeds can be matched according to working conditions，Comprehensive energy saving 10%。Large diameter drum，Single-layer winding of steel wire rope under full drilling state，And that service life is long，And that use cost is greatly reduce.。

◆Winch pressurization

The pressurization stroke is long，High pressure，Meet the construction requirements of the fully protected simple shaft。

◆Mountains, rivers and auspicious clouds

Cell phoneAPPEfficient management and control of multiple devices，View construction data and progress at any time。

◆Automatic lubrication

Standard centralized lubrication system，Lubricate regularly and quantitatively，Maintenance is more convenient。
