GS450-LS Trenchless HDD Horizontal Directional Drill

Introducing the latest innovation from Shanghai Goodeng International Co., Ltd., the walking drilling rig. This cutting-edge system is equipped with a steel crawler featuring external rubber plates and wire-controlled walking, with 2-speed adjustable capabilities for optimal control. The loading system includes a rotary manipulator and optional automatic rod-loading box for maximum efficiency. The drilling system offers thrust-pullback speed adjustable in three speeds (high speed, medium speed, low speed) to suit various drilling requirements. The operating system boasts a panoramic rotating cab, complete with heating and cooling air conditioning for operator comfort. Additionally, this rig offers the option of a crane and a power head that provides reinforced power. With these top-of-the-line features, our walking drilling rig sets a new standard in the industry, making it an essential tool for any drilling operation

Main Performance Characteristic

Close-circuit system is adopted for rotation system; automatic variable system is adopted for thrust&pullback、clamping and walking, and it is under load-sensitive control. Advanced hydraulic system raises more than 20% productivity, reduces about 50% heat, and saves more than 20% energy compared to traditional one.

The machine is equipped with Cummins engine, with high efficiency, large power, low fuel consumption, low noise, and strong ability in construction.
Four-bar linkage luffing structure is adopted for main girder, which highly increases entry angle range and ensures the large angle and rig tracks are not off ground, having improved the safety performance.
The machine is equipped with Ф83×3000mm, and the machine body occupies a moderate area, meeting the requirement for high efficiency construction in small place.
The steel track with rubber plates is adopted for crawler, which can not only bear high load, but also satisfy walking on different roads.
Rack and pinion system is adopted for thrust&pullback, which is good for high efficiency, long life, stable working and convenient maintenance.
