XCMG XR220 Rotary Drilling Rig
Main feature:
**XR220 utilizes the special chassis for rotary drilling rig, which is designed and manufactured with advanced methods, featuring extra stability. The chassis structure is highly intensified, and it adopts heavy duty telescopic hydraulic track, which is convenient for transportation and has superior travel performance.
**The high performance main and auxiliary winch is built inside the slewing platform, which is convenient to operate. The main winch has the function of controlled free release to ensure the speed synchronization between the drilling head and the steel rope.
**The PLC control can be operated automatically/manually to achieve the verticality of mast; Automatic inspection and alarming on the pressure of key points; Real time inspection on the boring depth; Dynamic and numerical display, automatic/ manual lifting and descending the drill mast, and color LCD.
**The patented parallelogram luffing mechanism can cover wide work areas; The drill mast is designed as box structure made of high strength materials, which ensures the boring precision with higher rigidity and strength. And all the articulated points adopt lubrication-free bearings.
