Zoomlion ZR550L Rotary drilling rig

1.Three slewing reducers，Ffectively enhance the braking effect when entering the rock，And that integral stability is increase，And that drill accuracy is ensured；Central single main winch，Whole machine force is more reasonable，Single layer steel wire and long service life of steel wire rope；

2.The main winch has the function of bottom protection.，Simulate the operation habits of senior hands，Automatic rope avoidance：

3.The main winch has hole bottom buffering function.，Reduce the speed step by step before the drilling tool is lowered to the bottom of the hole，Avoid larger instantaneous impact when the drilling tool touches the bottom，While protecting the pressure pipeline system, it also ensures the stability of the whole machine.；

4.Adding high efficiency mode under pressurized working condition，And that work efficiency of continuous hole forming is improve.；＊The force head has rock penetration，Meet the construction requirements of complex formation；

5.Equipped with power pin pulling device，Realize automatic disassembly and assembly during equipment transfer，And that labor intensity of the operator is reduce；

＊The crawler travel system is equipped with four jacking outrigger cylinders.，It is very convenient to disassemble and assemble the roof belt and get on the flat car.，It can save a lot of new transshipment costs for customers.；

6.The four top open oil Reds and the four extended oil rivers can realize the communication control operation.，Convenient, fast, safe and reliable：

7.Full-automatic centralized lubrication system，Facilitating the maintenance of the drilling machine，Labor intensity of light workers；

8.Full human-computer interaction interface，Good sight，Smarter，Humanized operation is more comfortable;

9.A new generation of electronic consoles，360-seat full-view monitoring，Cell phoneAPPPush device information，Safe and convenient。
