High efficiency Pile Top Drill Rig ZJD4000 / 350C for Superstructure / building

The Best Drilling Machine Pile Top Drill Rig ZJD4000 / 350C with RC Drilling Method is Better Than Rotary Drilling

Our ZJD series pile top drill rig provides the most efficient solution for foundation drilling in mixed ground, boulders and hard rock. Multiple machine models cover the diameter range from 0.8 to 5.0 m, and can also be used to drill inclined, battered or raker piles. We also provide a full range of hydraulic power packs and other components, such as clamping device, drill string (drill pipe), drill bit...

ZJD4000/350C full hydraulic drilling rig has the basic feature of:

• Large dia (about 4.0m)
• Depth (more than 160m)
• Hard rock (75Mpa ~ 250Mpa)
• Bore piling in marine conditions, gulf area, port,

And it's mainly used for Onshore and Offshore Foundation, such as:

• Superstructure and building
• „Anchoring of oil and gas platform
• „Marine structure, such as harbor, pier, jettie, berth and dry dock
• Bridge and pier
• „Offshore wind farm
• „Dam rehabilitation
• Disassembly of oil and gas platform
