Rotary Drilling Rig

Features
1. The famous brand strengthened chassis which is specially designed for hydraulic retractable crawler not only facilitates the transport of our rotary drilling rig but also improves overall stability.
2. An electronic injection engine is used for great reliability and high fuel efficiency, with the maximum power up to 213KW.
3. Key hydraulic components are imported for reliability. The power transmission system adopts intelligent control, and thus realizes overall power load adaptive control. The power units such as motor and reducer are world famous brand products, ensuring strong power. High strength gear drive helps achieve the maximum torque of 220kN.m.
4. Sophisticated control technology is used to control the working parameters of our drilling rig. The color touch screen can display the detected information and record in a timely manner. Touch screen operation improves the operation accuracy, and reduces labor intensity as well.
5. Electro-hydraulic proportional technology is utilized to realize precise positioning of upper structure.
