LIUGONG SD30A Multi Functional Drilling Rig
Product Feature
- A new generation of dedicated chassis: 299kW engine ,meeting Euro III emissions standard ,high power and high durability; Heavy weight, low center of gravity, and greatly improved stability during working period; providing stable and reliable power for the whole machine.
- Rotary head : Multi rotary speed control system ensure higher drilling efficiency, long-guided three-sided wear-resistant structure design;High vertical drilling accuracy; Double buffer system improving protection ability.
- The main winch adopts a long drum design, which effectively improves the working efficiency and extends the life of the wire rope.
- Energy saving and environmental protection: Multi-pump in series and parallel system and specially designed on main valve can reasonably perform power distribution, reduce energy consumption, and increase the output power of the main valve.
- Superimosed counterweight design, which can flexibly increase or decrease weight according to the configuration and actual working conditions; 3,715mm ultra-small slewing radius increases drilling safety and operation flexibility; option for the chassis equipped with external counterweight.The integrated hydraulic system and electrical system make the operation more flexible and reasonable, and the power output changes reasonably, which effectively improves the efficiency of energy and achieves energy saving and consumption reduction.
