The "F" has come! Pile foundation operation of XR138F low clearance rotary drilling rig with height limit of 10m

Under a high-voltage wire with a height limit of 10 meters，Xugong New National Grade IVXR138FLow clearance Rotary Drilling RigWith a roar，Continuously lifting and lowering the drill pipe to construct the supporting pile of the pipe gallery。

Construction site along the south extension of Changchun Rail Transit Line 4，Above the operation is the high-voltage line.，The client requires that the construction shall be carried out under the condition of meeting the height limit of 10m.，The rotary drilling depth shall be more than 18 meters.，Other than that，After the completion of the projectXR138FBe able toRotary Drilling Rig refitted into standard state。

XugongXR138FThe first show of the low clearance Rotary Drilling Rig was met.“Urgent work”，The project needs to ensure the stability and reliability of the underpass pipe gallery through supporting piles.，300 supporting piles are added to the whole project.，Drilling depth 18.5 meters，Borehole diameter 800mm，In order to leave enough time for the subsequent construction，The construction time of pile foundation is tight.，XR138FWhile being efficient, we should stick to the front line of construction 24 hours a day.。

Newly upgraded XCMGXR138FRotary drilling rig is suitable for industrial and civil construction.、Municipal、Power grid, power pile, etc.，In the soil layer、Sand layer and other geological construction efficiency is higher，The complete machine is transported with a rod，Transition is more flexible。What's more,，At the end of this project，XR138FCan be converted to standard condition within three hours，The multi-use of one machine greatly reduces the cost input of users.。

AsFThe first battle of the series，XCMG in standard stateXR138FPerformance is more powerful，ItsMaximum drilling depth: 46m，Borehole diameter 1.5 meters，Maximum speed of power head 45rpm，And the use of large torque reducer and 28mmWire Rope，Maximum lifting force 16 tons，The construction capacity is strong，Safety and reliability are also much higher than peers.。

While ensuring the surging power，It is also equipped with the fourth Cummins turbocharged engine.，Fuel consumption is 5% lower than that of the same level engine％。This is highly appreciated by the customer：“It strengthens the power.，It also reduces fuel consumption.，Absolutely great fire！”

XCMG medium and small tonnage rotary drilling rigs are known as industrial and civil construction“A small steel gun”Known as，This new upgradeFThe series originates from XCMG's strong independent innovation capability and profound technological research and development capability.。XCMG Rotary Drilling Rig Will Continue to Focus on Customer Demand，Casting fine works with ingenuity，Cultivate the future with integrity。
