Product Description

MWDL-350 mechanical top drive drilling rig is a kind of drilling equipment independently developed by the company

that 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 as

hydraulic transmission, lower power drive, more efficient and energy-saving.The low-light problem of ring drilling rigs for

beads and pebble layers.
