3 meters！It may only be the height of one story.，But in the renovation project of old residential areas in the center of Shanghai,，But it is an insurmountable safety red line.。Short fuselage、Hard physique、Strong heart，SMD-CThe 65 low clearance cast-in-place pile drilling rig is developed to meet the construction requirements of limited height.，Apply it in high-rise building、Under the bridge、Station reconstruction, etc. Low、Construction operation in highly confined space，Move height 2.2m，Construction height 2.9m，Make the construction site of pile foundation no longer limited，It not only perfectly solves the construction problem of low space pile foundation in construction projects, but also solves the construction problem of low space pile foundation.，It also shows the strong R & D strength of Shanggong Machinery as an underground equipment manufacturing enterprise.。

▲The height limit of the project site is 3m.

  

▲The construction site space is narrow.

  

▲Complicated construction site space

SMD-CThe 65 design is a new type of drilling rig mainly used for drilling in narrow spaces.，Strong drilling ability，With customized industrial wireless remote control，The operation is convenient，Pile diameter of the first test pile 1m，Pile depth 24m，ROP 22.5m/hHigh efficiency and smooth completion，Not only is the construction period short、The cost is low，Little impact on the surrounding environment，Its working efficiency is much higher than other similar piling equipment.。

Shanggong Machinery always adheres to the market-oriented principle.，Take technological innovation as the background，For different user needs，Develop a series of construction tools with strong pertinence，And among themPJR160 micro pipe jacking drill、PITPipe rubbing machine、SMD-C73 Low clearance cast-in-place pile drilling rig and many other rich and advanced low clearance construction products, supplemented by a complete set of construction methods.，It perfectly meets the working requirements of complex working conditions.，Solves numerous construction challenges in narrow environments。
