Product introduction of roof bolter MDL-150F

Anchor drill mdl-150f is a high-efficiency drill developed by Wuxi Zhimai Construction Machinery Co., Ltd. according to domestic subway, high-rise building, airport, ground source heat pump and other deep foundation pit for anchoring, rotary jet and dewatering lock. The drilling rig is integral and equipped with crawler walking chassis and clamping shackle. The root canal drilling tool can be used to follow the casing to form a hole, and the functions of free rotation and rotary jet are added.

Introduction to MDL-150F anchor drill 

The torque and rotating speed can be reasonably matched according to the actual needs. The stroke of the propulsion frame is 3.4m, which can carry out the compound drilling of 3M drill pipe and casing. The gyrator with corresponding torque can be configured according to different strata, which improves the adaptability of the drilling rig.

It is equipped with crawler chassis, high-level rotating platform, large-diameter outrigger oil cylinder, 0.9m sliding frame and orifice support device, which makes the displacement and positioning of the drilling rig very convenient and stable and reliable during drilling.

Equipped with clamping shackle, it has low labor intensity and high efficiency for loading and unloading drill pipe and casing.

Construction characteristics of roof bolter MDL-150F

Three wing bit drilling and mud slag removal. It is suitable for high-speed drilling in soil layer, sand layer and other strata; Air DTH hammer drilling and air slag removal (high configuration cost, more than 15 cubic meters of air compressor, DTH hammer and large pollution) are suitable for rock formation and broken layer construction; Bottom hole hydraulic hammer drilling and mud slag removal. (low configuration cost, equipped with bw-320 pump, hydraulic hammer and less pollution) it is suitable for construction according to stratum with large water content such as broken layer and sand egg layer.

Casing drilling; Compound drilling of drill pipe and casing; Foundation pit dewatering; Micro cast-in-place pile; Single, double, triple rotary jet, fixed jet, swing jet and other rotary jet processes.

Geothermal hole (well) construction and survey (equipped with winch module and orifice device module, which can carry out survey and construction within 100m); Static cone penetration test (5T static cone penetration test); Dynamic penetration.
