Advantage introduction

      • Selected the powerful Cummins engine, with the electronic control system and hydraulic system of the core technology of Zoomlion, giving full play to its working abilit
      • Internationally advanced CAN BUS technology, virtual instrument in conjunction with the unique sensor, providing precise control and monitoring of operating condition for the rotary drilling rig
      • Zoomlion-made carrier dedicated to the rotary drilling rig perfectly matches the power system with the hydraulic system, improving the efficiency and energy-saving of the hydraulic system
      • Three motors and three reducers for rotary drive, with strong power and high power reserve
      • Optimized and lowered CG of the rotary drilling rig, increased effective push-down force and improved efficiency of rock drilling
      • New-generation rotary drive and new second-level buffer, which improve the structural strength and the stability of rock drilling; the lengthened guide improves the precision of rock drilling
      • Increased ground contact length and width of crawler improves the stability of the rotary drilling rig
      • The domestic initiative traveling system-countershaft structure for rotary drilling rig, significantly increases the lap length of structure in operation, and improves the stability of the rotary drilling rig
      •  Optimally designed guyed mast, with high strength, light weight and good rigidity
      • A newly upgraded operating system is applied to provide the operation mode of combining the screen and the panel, which improves operation convenience so that the comprehensive information management can be realized by using the operating system together with the corresponding mobile app
