Zoomlion ZR300L Rotary drilling rig
Product Feature
1.The mast is folded，Height of complete machine: 3520mm;
2.Dismantling-free mast support，The transition is convenient and fast；
3.Large Mast Section、Quadrilateral luffing mechanism with double moving arms、Large diameter slewing bearing、Reinforced chassis，Make the machine structure more stable，The bearing capacity is stronger；
4.Three power head reducer，The torque is large，High reserve factor，Construction capacity is stronger；
5.Adopt main pump with large flow、Multi-gear power head、Two-speed pressurized cylinder，More efficient construction；
6.Main winch with central single-row rope、One drum and two machines，Better lifting ability；Single layer wire rope，**And the service life of the steel wire rope is greatly prolonged.；
7.Adopt a new generation of cab、New human-computer interaction interface，Good sight。The operation is more comfortable；
8.New generation of electronic control platform，360-degree full-view monitoring，Cell phoneAPPPush device information，Safe and convenient。
