DFQ-150W drilling rig is a lightweight, high efficiency and multi-function drilling equipment,itadopts crawler, self-propelled,applicable to rough terrian. It adopts to two kinds of working way---with mud pump or air compressor, strong applicability. 

 1.It is widely used for water well drilling,geothermal air-conditioning project and other boreholes, especially applicable to mountain area and rock formation water engineering.
2.Much higher efficient than the traditional rotary drill rigs, creating the considerable economic benefit for users. 
3.Especially solve the problems to drill very hard rocks that the traditional rotary drilling rig meet, our DFQ-150W is able to work efficiently under all kinds of geological conditions.

Our drilling rigs are widely used for water well drilling, irrigation well drilling, geothermal hole drilling, mining blast hole drilling, construction pile work drilling, air-conditioner hole drilling, etc.
 
DEFY Brand drilling rigs have been widely exported to Chile, Russia, Australia, Malaysia, Kenya, Tansanzia, Zambia, South America, Peru, Zimbabwe, etc.
 
Every customer is very welcomed to our factory for visiting driling rig,  talking onsite and details. ^_^

 How to choose a suitable drilling rig? 

1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?

2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more. 

3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.

4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one. 
C. Mainly hard rock, like granite.

Based on the above information, DEFY experienced engineers will help you recommend suitable machine and price. If you have special demands, please tell us ahead.
