Product Description

YZJ-300Y Crawler Type Drilling Rig:
It is widely used in the geological general investigation and exploration, road, railway, port, bridge, water conservancy, tunnel and tall building basic exploration, kinds of hole in concrete structure, river, levees, subgrade grouting hole drilling and direct grouting, civil wells and earth central air conditioner, and etc.

Main features:

1. It equipped the automatic hydraulic lifting drill tower, form the lift and drop tower is hydraulically operated, it is convenient and reliable, save time and reduce labour intensity;

2. The rig is equipped with crawler running gear and hydraulic cylinder pillar, the whole relocation convenient, easy to rig the level of adjustment;

3. The oil pressure to enter institutions, improve drilling efficiency;

4. Rig equipped with a cassette holding mechanism on the ball instead of a chuck, can be implemented without stopping the machine down lever, high efficiency, easy operation, safe and reliable;

5. With socket pressure gauge indicates pressure, easy to grasp the hole situation;

6. Diesel engine with electric start, reduce labor intensity;

7. Rig is easy for operation, with high performance, easy maintenance, less investment and quick.聽

8. With 4 high legs, it is very convenient for transportation without crane.

9. The mud pump can be mounted on the crawler, it can save cost and space.
