ZJD1800 / 80 Full Hydraulic Drilling Rig with Large Diameter Drill
Pipe for Cast-in-situ Piles or Bored Piles
ZJD1800/80 full hydraulic drilling rig is mainly used for drilling
construction of pile foundation and vertical
well with small-medium diameter in complex geology. The maximum
drilling diameter and depth are
1.8M and 120M,the biggest embedded rock strength can reach 150MPA.
It is Widely applied in drilling
construction of large building on land,port and pier, river levee
protection,and river, lake, sea bridge
pile foundation, and it’s the main model of small-medium
diameter pile foundation construction.

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
Main performance and features
1.The maximum drilling diameter and depth are 1.8M and 120M, the
biggest embedded rock strength can reach 200MPA.
2, High efficiency and energy saving, full hydraulic stepless speed
change, reliable and stable transmission performance.
3, Large torque, large lifting force, especially suitable for
complicated stratum such as gravel, hard rock etc.
4, The suspension tiltable power head and tiltable frame with
compact and reasonable structure, easy to assembly and disassembly.
5, Large diameter drill pipe, using high-pressure gas lift seal
device and advanced RCD method.
6, Optional additional weight to increase pressure in hole bottom,
ensure the verticality of the hole.
7, Optional stabilizer to assist drilling, effectively control the
verticality and hole diameter precision, reduce drilling tool wear.
8, Simple operation, low maintenance cost, comfortable environment
of operation room, optional installation of temperature adjusting
9. 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.
10. Easy to collect samples. Any depth of the sample will help to
study and analysis of geological condition.
