【2021】Add rotary regulator & feed regulator to prolong the life of rotary head & feed motor.

Clamp device for horizontal drilling (Option)

When the ordinary DTH pneumatic  crawler drilling rig carries on the horizontal drilling, will appear the borehole deviation problem.To solve this problem, our R& D team added a drill rod clamping device to QIN-PCR200-DTH pneumatic crawler drilling rig to ensure accurate horizontal drilling.

QIN-PCR200 DTH economic benefit

Matching with high wind pressure air compressor, the drilling efficiency is 36 m/hour.
8 hours/day
320 working days/year

• QIN-PCR200-DTH drill depth: 92,160 m/unit/year
• QIN-PCR200-DTH production capacity : 1,317,888 m3/unit/year

Why QIN-PCR200 DTH ?

• Compare with DTH hydraulic crawler drill:

As the hydraulic system and diesel systems ability to adapt to the summer heat is weaker than a pneumatic crawler rock drill, and the difficulty of maintenance work volume greater than pneumatic drills. 
For example, Pakistan into the rainy season (May - October) and dry season (November - April), rainy season hot and wet, the temperatures between 20-40 degrees, the dry season temperatures between 30-50 degree. 
For the hydraulic oil is also a severe deterioration than China, so compare with pneumatic crawler drill, the heat dissipation, maintenance, spare parts supply,etc.,is a big problem.

• Pneumatic crawler drill’s climbing ability adapt to a more complex field operating environment, smooth transitions, can temporary short distance towing — particularly suitable for the rugged complex initial mine construction site.
• Less maintenance, less ancillary time, low failure rate pneumatic components, easy maintenance, anti-high temperature.
