MGL-150S type

 

Product Description

The MGL-150S type crawler-mounted high-lift anchor drilling rig is an efficient drilling machine developed by Wuxi Banshan Construction Machinery Manufacturing Co., Ltd. for anchor drilling, jet grouting and water extraction in deep foundation pits for domestic subway, high-rise buildings, airports, ground source heat pumps and other projects.

 

Main purpose:

1  The maximum rotational speed can reach up to 170 revolutions per minute compared to MGL — 135D has increased by 20%, which is particularly beneficial for using twist drills and improving the efficiency of the soil layer.

2  Energy-saving and highly efficient; without increasing the power, it effectively enhances work efficiency.

3  When the rotational speed increased, the torque compared to MGL-135D increased by 10%, and the maximum torque rose to 7500 NM.

4. A new type of hydraulic system has been adopted, which results in a simpler structure, a more reasonable layout, and more user-friendly operation.

 

2.  Compared with the previous period, the construction efficiency of the MGL-135D drilling rig has increased by approximately 20%.

3.    The maximum lifting height is 3.3 meters. The double-cylinder bucket arm design of the excavator ensures excellent stability in any lifting position, allowing for simultaneous construction of up to two rows. Three-row holes save time and enhance efficiency. They can be used for construction in horizontal, vertical, inclined, and negative angle positions, meeting the needs of various construction techniques.

7. The entire machine is equipped with a cover shell, which not only makes the machine's appearance more scientific and aesthetically pleasing, but also protects the key hydraulic components from contamination. Common construction techniques:

1  The three-blade drill bit drills in and discharges the mud. It is suitable for high-speed drilling in soil layers and other types of strata.

1.  Air submersible hammer drilling is used for penetration, and air is employed for slag removal. It is suitable for construction in rock layers and fractured areas.

2.  The hydraulic hammer drilling at the bottom of the hole is carried out, with the mud used for removing debris. It is suitable for construction in layers with high moisture content such as clay and sand-egg layers.

4  Casing drilling.

5  Composite drilling of drill pipe and casing.

6  Single-stage, double-stage, triple-stage jet grouting, fixed jet grouting, swinging jet grouting, etc.
