Nanshen High-speed Railway is a transportation hub project invested and constructed by Guangxi in an all-round and in-depth docking with the development of Guangdong-Hong Kong-Macao Greater Bay Area.。The design speed is 350 kilometers per hour，The construction of the line will promote regional economic development.、It is of great significance to improve transportation efficiency.。

Recently，We came to the Yucen section of the Nanshen Railway.，The super-large bridge of Guangxi Yucen Railway Bid 1 Project is under construction here.——Beiliu CrossG59 Hubei Expressway Super Major Bridge。The total length of the bridge is 7124..39 meters，It is also a new Nanning-Shenzhen Railway from Yulin to Cenxi.（Boundary between Guangxi and Guangdong provinces）The key and difficult projects of the section。At the construction site，The machine roared，Each construction team carries out bridge foundation construction in an orderly manner.。Among them, the most striking are two Yuchai rotary drilling rigs with towering red masts.。With the roar of the machine's engine，The hydraulic motor powerfully drives the drill rod to carry out the drilling operation，From time to time, there was a sound of rock friction and cracking.，Indicating that the borehole has reached the rock layer.。

According to the staff of the project department，YuchaiYCR405EThe rotary drilling rig is faced with complex stratum conditions in the construction process.，Including backfill、Silty clay and hard slightly weathered dolomite。The construction pile diameter is required to be 1m.，The hole depth reaches 45 meters.。In addition，Due to tight schedule of the project，It poses a great challenge to Yuchai's equipment and service team.。However，It is gratifying that，Yuchai Rotary Drilling Rig, with its efficient and stable construction performance, makes the project steadily advancing.。For months.，Yuchai rotary drilling rig has been working continuously for more than one thousand hours.，The customer is very satisfied with it，Praise Yuchai equipment for helping a lot.。At first，Customers are still worried about such a harsh construction environment.，Be prepared for a delay in completion。However，With the deepening of Yuchai rotary drilling rig construction,，Customers have more confidence in Yuchai's construction plan and equipment.，He said that he would celebrate the success of Yuchai after the completion of the project.。

YuchaiYCR405 rotary drilling rig is a large rotary drilling rig specially developed for rock entry conditions.。It has a borehole diameter of up to 3 meters.、The maximum drilling depth is 99 meters.、The maximum output torque is 405 kN·mThe characteristics of。The whole machine weighs 120 tons in working condition.，Equipped with special telescopic chassis for rotary drilling rig，Largest size，And is more beneficial to actual output of various main parameter.，And that work efficiency is high、Powerful，The pile foundation construction can be completed quickly and accurately.。

Yuchai has been committed to technological innovation and product quality improvement.，And actively participate in the construction of key national projects.，To make positive contributions to national and regional economic development.。
