Features:

1. This drilling rig is applicable to work in mountain, loess, hill, plain, forest,gobi,  seasonal farmland for seismic prospecting, mine survey, geologic framework investigation etc such drilling project.

2. Drilling method includes air drilling DTH hammer drilling, mud drilling, and casing drilling. Adapt to different drilling operation with relative drilling method. Max drilling depth is 30 meters.

3. Self-adaption system to stratum shortens handle regulating time of driller, improves drilling efficiency and ensure perpendicularity of the hole.

4. We design and use DTH hammer with interconvertible high-low frequency according to situation of single using DTH hammer (low frequency, big impacting energy) in prospecting drilling project nowadays. Choose high frequency matching parts of DTH hammer to improve drilling frequency when soft formation as f≤8.

5. Use lithium battery with big capacity to reduce weight at max limit.

6. New design of power swivel that circulation drilling fluid and bearing chamber are separate reduces damage probability of bearing.

Configuration:

This drilling rig uses the modular design, disassembling fast, convenient and reliable. It includes engine, operating platform, the mast assy., the power swivel, the aerodynamic system, the drilling tool and other appendices.

Optimization design of direct-drive hydraulic pump, hydraulic tank and the reversing valve combination, reduces the loss of the system, the main mast assembly uses rectangular tube with welding slip way, to improve the safety of using, transportation more convenient.

Pull up & down of drilling tools is achieved by hydraulic motor driving roller chain.

Drilling rig equipped with the weight balance valve and relief valve to ensure steady pull up & down of drilling tools with load. Improve system security and safety.

The drilling rig equipped with safety and warning mark, meets the requirement of H.S.E. and improves the level of security of the rig effectively and reduces the frequency of security accident.

Appearance in red spray rig protection, the color enable the operator to concentrate on the warning color, that can reduce the accident rate, while the color in the atmosphere through a strong ability to help the search for the helicopter to support the project location.
