Should pneumatic crawler drilling rig be out of the picture?

PCR200 Top hammer crawler rock drilling rig

​Lately, we've been getting feedback from clients who are struggling to decide whether to buy a pneumatic crawler rock drill or a hydraulic crawler drilling rig?
​
CONSIDER THIS CLIENT:
"Too much fuel!  Air Guzzler!" This is a common complaint. Remember in the early years this kind of big crawler drilling rig began to be popular everywhere, haha, at that time the fuel price is low, the salary is also high. Money is not so easy to make these years, to save fuel we have a large number of old this kind of pneumatic crawler drilling rig, are replaced by a hydraulic crawler drilling rig with an engine. I miss the benefits of the air crawler drilling rig. It's simple to build, easy to repair, cheap parts, lots of energy, low center and easy to climb."

Well, as China No. 1 supplier of pneumatic crawler drilling rig, let's hear from the professional maintenance crew to find out what's so great about pneumatic crawler drills?

"This is indeed not economical in terms of fuel consumption, but the progress of the project has been dramatically enhanced."

MAINTENANCE CREW: Eng. Wang
BRAND NAME OF MAINTENANCE CRAWLER DRILLING RIG: Furukawa PCR200-DTH & INGERSOLL RAND CM351 & EPIROC / Atlas COPCO AIRROC D50 & YUAN-PCR200-Pro top hammer crawler rock drilling rig & QIN-PCR200-DTH pneumatic crawler drilling rig & HAN-D50-DTH (CM351) pneumatic crawler drilling rig.

Eng. Wang:

1. Be Able to say this point, that you do not have enough time in the quarry operation of hydraulic crawler drill and pneumatic crawler drill, these two kind of crawler drilling rigs to make a full comparison ~Although the Ingersoll Rand CM351 & Furukawa PCR200-DTH is an early product, many drillers think the air-powered crawler drilling rigs are behind the curve, but it's a good comparison to make now.
2. From the use, although the pneumatic crawler drill fuel consumption, but can maintain a stable pressure output, the speed of penetration and the impact of DTH crawler drilling rig is significantly more significant than the hydraulic crawler drill.
3. In the speed, because of the steady pressure output of pneumatic crawler drill, so in the drilling speed is better than the hydraulic crawler drill.
   In a quarry I'm working on, I'm required to complete six kilometers of cubic meter in two months, one EPIROC / Atlas COPCO FLEXIROC T35, and one Furukawa PCR200-DTH pneumatic crawler drilling rig, working two shifts eight hours a day, the actual meter count is 3,800 meters, the ratio is 38:22! In terms of fuel consumption, the pneumatic crawler drilling rig shift is at 300 liters, and the ratio to the EPICROC / Atlas COPCO FLEXIROC T35 is 300:210. This is indeed not economical in terms of fuel consumption, but the progress of the project has been dramatically enhanced.
   You want to save money and want to be fast is impossible, and the pneumatic crawler drilling rig at least cost-effective! My repair shop has about 100 customers are using pneumatic crawler rock drill, they use some full hydraulic drilling rigs all recognized this ~
4. And finally, maintenance!
   The maintenance and spare parts of the pneumatic crawler drilling rig are less than DTH hydraulic crawler drilling rig a lot.

It is not the boss who thinks the hydraulic crawler drill is easy to use. We should evaluate the value of the crawler rock drill from the purchase cost, maintenance cost, use cost and capital Recovery Cycle! ！!
