Crawler type deep (water) well drilling rigs adopts full hydraulic control, top drive drives the rotation of drilling tools, and the drilling efficiency is extremely high. The overall layout is reasonable, and it adopts all-ground chassis for transportation, with good maneuverability.
[pdf] SWMC-SWDS 115AN integrates the advanced technology of the current split pneumatic drilling rig. The prototype has passed over 3000 hours of destructive operation experiments and 4 kinds of field tests in different geological environments. It has improved more than 10 mechanical loopholes.
[pdf] A rotary drilling rig is a construction machinesuitable for hole-forming operations in building foundation engineering. It is mainly suitable for sandy soil, cohesive soil, silty soil, fill layer, and silt layer, so.
