SimpleRecently，YuchaiYCR405ERotary drilling rig appeared at the construction site of Lixian Expressway in Pengjiagou Village, Tangya Town, Xianfeng County, Enshi City, Hubei Province.，Participate in the construction of the Yellow River Dam Bridge。

YCEfficient

The Yellow River Dam Bridge Project is located in the Wuling Mountain area.，Most are karst landforms.，The formation is hard and complex，With karst caves、Plagioclase、Mainly isolated stones，Engineering construction is difficult、The technical requirements are high。The construction pile diameter is mainly 1.5 meters、2.5 meters，Perforation depth is 30~55 meters，Subject to the design requirements。Newly upgraded YuchaiYCR405EFast pressurization function is added for rotary drilling rig.，The position of the power head can be quickly adjusted，Increase the speed of hole alignment，Improve construction efficiency。The hydraulic telescopic crawler chassis is specially used for the rotary drilling rig.，Equipped with large diameter slewing bearings，The main beam of the platform is made of high-strength steel.，The structure is more stable and reliable.，The stability of the construction is ensured.。YuchaiYCR405EThe rotary drilling rig has attracted much attention from the project department since it entered the construction site.，From fuel consumption to construction efficiency，The superior construction performance has been highly recognized by the project department.。
