Quarry contractors often lose drilling time because of worn bits, unstable air pressure, or equipment that lacks sufficient pulling force. A Pneumatic Hydraulic Crawler Drill Rig combines pneumatic impact drilling with hydraulic feed and rotation to handle hard-rock drilling across suitable quarry benches and uneven work areas. YG Machinery offers five models from YG-180 to YG-350, giving contractors options for different hole depths, drill-string loads, and site access requirements.

How Do You Select the Right Model for Your Drilling Work?
Start with the planned hole depth, drill-pipe dimensions, and expected pulling load. A deeper hole often means a longer, heavier drill string, so lifting force matters alongside drilling depth.
- YG-180 and YG-200: Suit projects with planned depths up to 180 m and 200 m respectively, where compact equipment and lower transport weight matter.
- YG-260: Covers drilling depths up to 260 m for contractors handling a wider range of quarry and construction jobs.
- YG-300: Reaches 300 m and offers up to 17 T of lifting force, making it a practical option for deeper holes and heavier drill strings.
- YG-350: Reaches 350 m and delivers up to 25 T of lifting force. Its maximum swing torque of 9,500 Nm supports demanding rotation and drill-string retrieval.
The difference between YG-300 and YG-350 is not just 50 m of additional drilling depth. Their maximum lifting forces differ by 8 T, which matters when retrieving long drill strings. The heavier YG-350 weighs 9 T, compared with 7.5 T for YG-300, so transport capacity and access conditions also enter the decision.
Where Does a Pneumatic Hydraulic Crawler Drill Rig Work Best?
Quarry blast-hole drilling is a common application. Limestone, granite, and other hard formations place heavy demands on impact tools. Crawler movement lets crews reposition the rig between drilling points without repeatedly loading it onto a transport vehicle, provided the bench supports the machine safely.
Open-pit mining requires equipment that can work across designated benches and handle planned hole depths. The hydraulic feed and rotation systems support controlled drill advancement, while pneumatic impact action breaks the rock.
Road cutting and rock excavation often involve uneven ground, restricted access, and changing drilling positions. Before mobilization, contractors should check track width, gradients, ground stability, and the available space for the compressor and service vehicle.
For water-well projects, a Crawler Water Well Drilling Rig suits sites where tracked mobility matters, while a Small Water Well Drilling Rig fits smaller jobs with limited working space. A Pneumatic Water Well Drilling Rig offers another option for water-well applications that use pneumatic impact drilling. These machines serve different drilling requirements, so buyers should match the equipment to the project rather than assume one rig covers every application.
For quarry and construction work, the correct bit, drill pipe, and compressor configuration matter as much as the rig itself. Matching these components at the ordering stage reduces avoidable setup changes after delivery.
What Makes the YG Drill Rig Range Worth Considering?
The five-model range gives contractors room to match equipment capacity to the job instead of purchasing the heaviest rig for every project. The listed models cover drilling depths from 180 m to 350 m, with engine power from 58 kW to 92 kW.
The higher-capacity models also offer greater lifting force and swing torque. For contractors handling several types of drilling work, this range supports equipment planning around hole depth, pulling requirements, and transport limits.
YG Machinery sells drilling equipment directly from its factory. Buyers can discuss model selection, drill-pipe configuration, working pressure, and spare-parts requirements with the supplier before placing an order. For export projects, specify the destination country, required documents, and any applicable engine or equipment configuration requirements when requesting a quotation.
How Did Five Drill Rigs Enter an Oman Quarry Project?
In July 2026, a quarry contractor in Oman ordered five YG-350 rigs for hard-rock drilling and blast-hole preparation. Abrasive rock increased drill-bit wear, while hot, dusty conditions made air filtration and compressor maintenance important parts of daily operations.
The contractor selected one model for all five units to keep the drilling setup consistent. Before shipment, the equipment team checked the hydraulic components, crawler mechanisms, and drilling functions. The buyer also arranged compatible drill pipes, bits, and compressors for the planned hole sizes.
After delivery, the crew positioned the rigs in the designated drilling areas and checked air hoses, connections, and working pressure before starting work. During initial drilling, the team monitored bit wear and air delivery, then incorporated filter checks into routine maintenance.
The contractor’s reported feedback was:
“The rigs have handled the hard rock well so far. We particularly appreciate the lifting capacity when working with long drill strings. Keeping five units of the same model also makes it easier for our mechanics to manage routine servicing and spare parts.”
A consistent fleet gave the maintenance team one model configuration to support across the site. The contractor could track drilling time, bit consumption, and downtime to guide future maintenance planning.ance procedures and keep commonly used parts in one inventory. The team continued tracking drilling depth, bit wear, compressor performance, and downtime to plan servicing around actual site conditions.
