The world's largest tonnage back-mounted rotary drilling rig

XR468F

The first show of construction is coming Common for soft and hard formation

Direct backward tilting of drilling mast during transfer transportation

Energy-saving efficiency value is full！

The other day，The world's largest tonnage back-mounted rotary drilling rig XCMGXR468FFirst show construction officially started，At the construction site of Zengtian Expressway in Baiyun District, Guangzhou，XugongXR468FBe valiant and heroic、The roar of the machine，Put down the rod、Drilling、Lift the lever、Throw the soil at one go，The efficiency of the first show is amazing。  

Granite rocks are widely distributed in the construction area.，Metamorphic strata and Quaternary loose beds locally，The geological structure is complex，And the construction pile diameter is 1..8m，Pile depth 30-36m，Opening 10mInto the rock，Rock hardness greater than 100Mpa，It is also such a difficult construction condition.，Let the project side choose the first back rotary drilling rig newly purchased.XR468FConduct military training。

Make its debut，XR468FLive up to expectations，The results are brilliant，With the construction efficiency of completing a pile in an average of 24 hours, the construction site engineers and technicians have been obtained.、Full marks for operators and project supervision personnel，Open up the market with strength。

XugongXR468FRotary drilling rig equipped with inlet 15LCummins' Latest Platform High Pressure Common Rail Engine，Hydraulic system with large displacement main pump and large flow main valve，And that strong output of the hydraulic system is ensure.，Unreservedly direct to drill pipe drilling tool working device，Work efficiency is off the charts；Power head 490kN.mHigh Torque， Carefully create the mode of entering the rock、Stepless speed regulation、Constant speed cruise、Drill pipe visualization and other practical functions，Give way to the rock Kardon“ Old 、Big、Difficult”Get a thorough solution，Soft and hard“Take all”，Efficient construction with immediate effect！

In addition，The main winch is equipped with an ultra-long-life reducer.，48 tons of super lifting force，Adopt XCMG's industry-leading single-row rope technology，Effectively solve the problem of wire rope wear，Improve the service life of steel wire rope 2—4x；Pecial telescopic crawler chassis，Large diameter heavy load slewing bearing，Double-arm large parallelogram luffing mechanism，Direct backward tilting of drilling mast during transfer transportation，One step ahead in speed，Mountain construction is no longer afraid of transition.！

XR468FWith a 12-inch touchscreen display，One key return、Throw the soil with one key、Bottom protection、Automatic voltage limiting，Maintenance reminder、Troubleshooting at a glance，Really reach the comfortable and intelligent control experience of car level。

It is reported that，Guangzhou Zengcheng-Foshan Expressway(Zengcheng-Tianhe Section)Engineering（Zengtian Expressway for short）Total length 38.4km，After completion, Guangzhou will be realized.“Expand in the south and optimize in the north，East to West”An important measure of space development strategy。
