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
First-class quality, First-class service, First-class technology
ZJD4000/350C full hydraulic drilling rig is favored by domestic and
foreign customers with strong
operation capability, advanced technology, high cost performance,
timely and thoughtful service,
and won industry praise. Compared with other piling equipment, has
the advantages of low investment,
high efficiency, quick recovery and so on, is an ideal choice for
pile foundation construction users.
Main Performance and Features
1, High efficiency and energy saving, full hydraulic stepless speed
change, reliable and stable transmission performance.
2, Large torque, large lifting force, especially suitable for
complicated stratum such as gravel, hard rock etc.
3, The suspension tiltable power head and tiltable frame with
compact and reasonable structure, easy to assembly and disassembly.
4, Large diameter drill pipe, using high-pressure gas lift seal
device and advanced RCD method.
5, Optional additional weight to increase pressure in hole bottom,
ensure the verticality of the hole.
6, Optional stabilizer to assist drilling, effectively control the
verticality and hole diameter precision, reduce drilling tool wear.
7, Simple operation, low maintenance cost, comfortable environment
of operation room, optional installation of temperature adjusting
8. High cost efficiency. the overall drilling costs can actually be
reduced by up to 40% when using RCD, safety and requires fewer man
hours, requires less water than other method.
9. Easy to collect samples. Any depth of the sample will help to
study and analysis of geological condition.
