MWDL-350 mechanical top drive drilling
rig is a kind of drilling equipment independently developed by the
companythat can drill at 75-90°,integrates water drilling and gas
drilling functions (national invention patent:
ZL201510479602.4),using 5-speed manual hemp, more Wide
range,sensitive and flexible conversion of positive energy, twice
as much ashydraulic transmission, lower power drive, more efficient
and energy-saving.The low-light problem of ring drilling rigs
forbeads and pebble layers. Drilling capacityDrilling
