GY-200 2A Engineering Drilling Rig
The GY-200-2A model engineering drilling rig is a lightweight and versatile drilling rig for engineering exploration and construction. It is suitable for geological exploration in industrial and civil construction, railways, bridges, hydropower, and other sectors, as well as for the construction of small-caliber foundation pile holes. It has the following features:
- A wide range of rotation speeds with reasonable gears.
- Low rotation speed and high torque, suitable for sampling and pile hole construction.
- Equipped with front and rear movable cylinders, allowing the entire drilling rig to move freely by 300 millimeters, which brings a lot of convenience for raising and lowering the drilling tools.
- Hydraulic feed, easy operation, high drilling efficiency, and low labor intensity.
-
Compact structure, small size, and light weight.
