Novo XCMG XR220E bušaće postrojenje

As a multi-functional machine, XR220E can realize the quick switching of functions such as crowd cylinder and crowd winch to meet more different construction needs.
The rotary drive performance is increased by 11%, main winch by 18%, travelling drive by 20%, heat dissipation capacity by 1.4 times, and the working efficiency is much higher.
The main and auxiliary winches both adopt single-layer rope technology. The service life of wire rope is 2~4 times longer than that of multi-layer rope, which makes the cost lower.
The parallelogram luffing mechanism with double boom has a large support angle and a 16% increase in support range, which makes the operation more stable.
The hydraulic system adopts negative flow control technology which has a fast response and good handling performance.
The intelligent control system can achieve functions such as automatic adjustment and display of mast verticality, automatic slewing, automatic spin-off, automatic lifting & concrete pouring, pile type display, etc. The bus panel design is adopted to prevent misoperation.
The rotary drive can be equipped with high-speed spin-off function and the rotation speed can reach 80r/min. The construction efficiency is higher with a spiral drilling bucket.
