GY-150B is a portable and multipurpose engineering exploration drill rig, applicable to the engineering geological exploration in fields of industrial and civil buildings, railways, bridges, hydropower engineering, as well as small-diameter foundation pile hole drilling.

Features:

1. The rotation speeds are in a wide range and gear-positions are rational.

2. When running with low rotation speed and large torque, it is applicable to drilling sampling and pile hole drilling.

3. When running with high rotation speed and equipped with small-diameter diamond bits, it is applicable to pile-test construction.   

4. Its hoist is a combination of friction cone and planetary gear, which features in advanced structure and good shock resistance.

5. Hydraulic feeding, easy to operate and high drilling efficiency;

6. The rotary table adopts a T-shape groove angle-changing device, with a wide angle-changing range; therefore the drill rig is capable of drilling with various inclinations.

7. Compact structure. Diesel engine and slurry pump are mounted on the same bottom frame, thus the drill set occupies a smaller hardstand apron.

8. Small in volume and light in weight; it is convenient to be disassembled and transported.

9. A fan equipped in worn gear reducer protects the oil temperature from overheating.
