Crawler water well drilling rig MW-400QSⅤ

Product Introduction

DMiningwell water well drilling rig is an efficient top drive, fully hydraulic, multifunctional drilling rig widely used for
drilling water wells, monitoring wells, precipitation wells, rescue wells, hot spring wells, ground source air
conditioning holes, coalbed methane, natural gas, oil extraction and other projects. This drilling rig can use
compressed air down the hole drilling or mud drilling in various formations in high-temperature, high-altitude,
and plateau areas, and has a high drilling speed in rocks with a Proctor hardness of f=4-20.
The lifting of the drilling rig frame, drilling rod unloading, rotation and feeding, support legs, hoisting, walking and
other actions of this series of drilling rigs are all implemented by hydraulic systems, greatly reducing labor intensity,
improving construction efficiency and engineering quality. The telescopic tower type drillingrig reduces the length
of the drilling frame by twice and can directly lower a 6-meter drill rod or casing, further shortening the drilling
assistance time. The updated rotary control panel can be used for different working conditions.
MW-330SV-MW-1000SV drilling rig features:
1. Advanced technology
2.Excellent quality
3. High operating efficiency
4. Strong adaptability
5. Reliable and durable
