Product Information of DFQ-200W Drilling Rig
DFQ series drilling rig is a kind of light weight, high efficiency and multi-function drilling
equipment, it is suitable for drilling water wells, agricultural irrigation well, geothermal air-
conditioning hole and other uses, especially for water engineering in mountainous and rock areas.
It is much more efficient than the traditional rotary drilling rigs ,can create very considerable
economic benefit for users. DFQ series drilling rig solves the problems to drill very hard rocks,
gravel, pebble stratum that the traditional drilling rigs are difficult to drill, DFQ series can work
efficiently under all kinds of geological structure.
