MDL-801 environment drilling rig

The whole machine adopts a new lifting structure with slip and offset function, and the construction scope is wider.


Engineering Drilling Rig


Main features:

1. The whole machine adopts a new lifting structure with slip and offset function, and the construction scope is wider.

2. The power head of drilling rig adopts the high end drive type impact rotary power head, high torque, high frequency and high construction efficiency.

3. The new type of propulsion frame is rigid and light, and it is equipped with high-end lift motor speed reducer to increase the pressure and lift force.

4. Install the top roll, make the upper and lower drill pipe and casing easy, and reduce the manual labor intensity.

5. The new type of orifice device has a large clamping force and a wider clamping range, and the multi-point slip structure is more reliable and does not damage the drill pipe.

6. The new type of folding control table can be extended to the orifice to facilitate observation and avoid misoperation.

7. The new type of pilot proportional hydraulic system, high efficiency and responsive, makes the operation more simple and reliable.

Scope of application:

1. Single, dual-pipe gas lift is circulating rock dust sampling.

2. Apply to the soil layer, and the spiral drill pipe of sand layer is drilled in high speed and deep hole, and the environmental monitoring well is set up.

3. It is suitable for drilling holes in rock formations, backfill layers and other complex stratum, so as to meet soil sampling and set up environmental monitoring Wells.
