Yuchai Rotary Drilling Rig Construction Changtai River-Crossing Connection Line Project

The geological conditions of the viaduct project are complex.，Near the Yangtze River，And the construction period is tight，The geology is yellow sand silt layer.，There is also a silt layer、Clay layer，The water table is high，It is easy to collapse，Pile hole diameter 1m，Single hole depth 40-70 meters。Yuchai rotary excavation relies on efficient and fast construction speed and mature construction scheme.，Help customers reduce operating costs，Time for forming single hole is about 2-3 hours。After several days of construction, YuchaiYCRThe excellent performance of 280 Rotary Drilling Rig in high efficiency and fuel saving has been highly recognized by customers.。

YuchaiYCRPerformance characteristics of 280 high-performance Rotary Drilling Rig：

●Full set of imported brand Rexroth hydraulic system，And that construction efficiency is high、And that performance is stable；

●Three-input power head，Power head gear setting，Adapt according to different working conditions，Efficient and fuel-efficient；

●New Large Braking Torque Slewing Reducer Makes Equipment Construction More Stable；

●Newly developed WeChat applet，It can monitor the working status and construction progress of the machine in real time.，Make it easier for customers to focus on their devices。
