Product Description
132m Hydraulic Crawler Rotary Drilling Rig XR550DD
1. It adopts the H-style dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience.
2. The main hydraulic system adopts the negative flow control, which can increase the system efficiency and make the most of the engine power. It adopt three-in-one cooling system which is tightly packed and has a high-efficiency in cooling.
3. It adopts the imported Cummins turbo-supercharged engine with three gears. It complies with Euro III emission standard, in addition, it has strong power, which is sufficient to satisfy the construction on the plateeue. It noise is up to the nation standard.
4. It adopts the luffing mechanism of large triangle form to ensure the stability of construction of big holes and deep piles in hard formation.
5. It adopts the single-rope main winch structure to greatly prolong the service life of steel wire rope and lower the use cost.
6. Normal mode and entering-rock mode of unit head are available for operation in soil and rock to improve the construction efficiency.
