DFLS-20 bore pile drilling machine is new pile foundation construction machinery, adopting hydraulic  walking type, electronic hoist, long spiral drilling. Hydraulic drive chassis canachieve 360° rotation, position, movement, leveling etc. Action are quick and accurate. 

Self-propelled  folded pile frame; uses two electric winches, can do drilling operation, also Lifting reinforcing cage on its own, perfusion operations. 

Power output shaft is hollow head, in addition to general long spiral dry method construction, 

but also for the construction of deep mixing method.

Established in 1970s, Zhengzhou Defy has growned into one leading drilling rig manufacturer in China, specilizing in drilling rig technology R&D, manufacturing, etc. We spark on conventional rotary drilling rig, new pneumatic drilling rig and are inventing another drilling rig with performance same as pneumatic one, but with much less investment for users.

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.
