Hydraulic Drilling Rig for Bridges, Marine,Super structures and
building Pile Foundation with 150M Depth
ZJD3500/250C full hydraulic drilling rig is mainly used for
drilling construction of pile foundation and vertical
well with large diameter and depth in complex geology. The maximum
drilling diameter and depth are 3.5M
and 150M, the biggest embedded rock strength can reach 200MPA. 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 large diameter pile foundation
construction.

First-class quality, First-class service, First-class technology
ZJD3500/250C 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. It is convenient to use that it is made identified caving part
and generation device, the work maintain management cost can be cut
down compared to competitors.
3. It is made minimized its volume and weight, and it can be moved
files without separating power pack and tower.
4. All movements are composed of oil pressure ways, there isn't
power failure on work, and it is easier to operate.
5. The caving support of master contrived especially makes Vertical
angle the best effect.
6. Stabilized bush used new material was certified long life and
economical value.
7. Easy to collect samples. Any depth of the sample will help to
study and analysis of geological condition.
