Product Description
Since the end of 2008.a new product that our company Portable Vertical Borehole core drilling machine accounted for 90% of China"s market,best-selling degree is self-evident,snapping up to buy most of China"s mountainous region,for instance,Chong qing,Guizhou and other regions in Sichuan and so on.For the convenience of export,company gave further improvement,machine accessories mostly adopts imported parts,especially the proportional valve performance is superior.Welcome friends from all over the world to come to cooperate.Thanks.
Portable Vertical Borehole core drilling machine is mounted with hydraulic top-driven system with compact and strong structure to work in the toughest working condition. Portable Vertical Borehole core drilling machine can be used in any of the most difficult area that vehicles can not access, such as: sharp mountain, hill, heavy forest, etc. Portable Vertical Borehole core drilling machine has good performance in drilling on hard rocks in high efficiency.
Borehole core drilling machine has sufficient drilling capability in different drilling methods: air drilling, mud drilling, auger drilling or with DTH hammer.
Can choose to use gasoline engine or diesel engine as the power of drilling rig.The reliability, efficiency and quality reputation has been set up among clients by several thousands units of portable drill rigs used in different countries.
The drilling rig can be disassembly into different modules within 10 minutes. The weight of the heaviest module is less than 100kg. Helicopter lifting hook are mounted on each rig,can be carried in a mountain area by a man!
The portable drilling rig has nominated performance: in the area that altitude 0-3000m above sea level, -10°Cand +56°Cambient temperature in dusty environment.
Product Features
The pneumatic drilling rig is installed with safety, caution and environmental protection signs, and it meets with the requirement of HSE.
