XR200E Rotary Drilling Rig
The XR200E rotary drill rig enjoys the following features.
- (1) It adopts Isuzu electronically controlled turbocharged engine with high power and low fuel consumption.
- (2) The double jib parallelogram luffing mechanism has a large support angle and a 16% increase in support range, which makes the operation more stable.
- (3) The main and auxiliary winches both adopt the single-row rope technology. The service life of the wire rope is 2~4 times longer than that of the multi-layer rope, which makes the cost lower.
- (4) The hydraulic system adopts negative flow control technology which has a fast response and good handling performance.
- (5) The rotary drive can be equipped with high-speed spin-off function, with rotation speed up to 80r/min.
As a multi-functional machine, XR200E can realize the quick switching of functions such as crowd cylinder, crowd winch, CFA and dual rotary drive to meet different construction needs.
