Product Description
 DFQ-200 200m dth portable borehole drilling rig
I. General Description
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.
