Changsha Zoomlion Heavy Industry Science& Technology Development Co.Ltd

From as early as the end of the 1980s, Zoomlion, based on nationalscientific research institutes, has taken the initiative in developing the ratary drills with walking chassis. Today, with solid specialty foundation and a profound understanding of piling technology, Zoomlion Shanghai constantly presents new rotary drills! The process of solving problems from the market front shows the essence of Zoomlion ratory drills: efficient drilling, accurate positioning, low consumption, energy saving, safety and reliability. Shanghai Zoomlion branch is one of the 7 divisions of Zoomlion dedicated in the R&D?manufacture and after-sales service of Rotary Drilling Rig, the factory is located in Shanghai and has a 18 years of research experiencs about the machine. Now we have near 300 stuff members and the research institute attracts more than 20 technicans including 2 doctors, 6 national researchers and the senior engineer takes a high 60% proportion,all of this guarantees excellent R&D capability and effective after-sales service. ZR Series Rotary Drill Rig is efficient equipment for large-bore pile foundation engineering. It has high drilling torque,and it is of efficiency,mobility,multifunction,and wide usage,good performance,easy installation,convenience and so on. It employs special extendable chassis, self up-down foldable mast, telescopic kelly bar,hydraulic pilot and load-sensitive control system. It also has other characteristics which include automatic hole depth measurement, automatic vertical alignment and automatic slewing positioning.its integrated monitoring system directly displays working status parameters, and its logical function control avoids mal-operation.Key components, such as ?four-rollers and one-track?, hydraulic parts,microprocessor unit, display,gearbox,and electronic control subsystem,are all from foreign famous manufacturers. It has strong power, stable performance and high reliability, so the machine is ideal equipme
