DTH drilling equipment is a complete drilling system that combines the hammer, rig, and air compressor into one integrated unit. It typically works in quarries, mines, and construction sites. This setup offers fast penetration in hard rock.
Integrated design means you get everything on one chassis. No separate compressor trailer. No complicated hose connections. Just drive it to the hole and start drilling.

Features of YG Integrated DTH Drilling Equipment
Power system. The YGS series uses Yuchai diesel engines. These engines deliver consistent torque for hard rock drilling. Fuel consumption stays reasonable across long shifts.
Mobility. Crawler undercarriage handles uneven ground. The YGS300 offers two walking speeds for moving between holes. The YGS350 reaches 4km/h on flat ground.
Drilling control. Operators control feed speed and rotation from the panel. This lets you match drilling parameters to rock conditions. You get faster penetration without wearing out bits.
Compact footprint. The smallest model, YGS153, measures 4640mm long. It fits into tight quarry benches where larger rigs cannot reach.
Stable performance. The integrated design keeps the hammer aligned with the hole. This reduces deviation and improves hole straightness.
Applications: Where Integrated DTH Drilling Equipment Works Best
Quarry blast holes. Limestone, granite, and basalt drilling for aggregate production. The YGS180 handles 90-146mm holes at 2.5km/h walking speed.
Opencast mining. Coal, copper, and iron ore operations use DTH rigs for production drilling. The YGS350 offers 90-165mm hole diameter for larger blasting patterns.
Water well drilling. Rural and agricultural water access projects. The YGS100A reaches 3.2m horizontal height, suitable for shallow well development.
Geotechnical investigation. Core sampling and site surveys for construction projects. The compact YGS153 works well in confined urban sites.
Road and railway construction. Slope stabilization and foundation drilling. The YGS300 provides 90-152mm holes with two-speed travel for job site mobility.

Real Case: YGS300 in a South Africa Quarry
A quarry in South Africa’s Limpopo province drills granite and diabase. Their old equipment averaged 6-8 meters per hour. Breakdowns caused frequent downtime.
YG supplied the YGS300 DTH rig machine. The 4-inch hammer matched their existing compressor. Penetration rates increased to 12-15 meters per hour. Fuel use dropped 15%.
The quarry manager said the rig ran 10-hour shifts with no mechanical failures in the first three months. Blast cycle intervals shortened. Aggregate production increased 20%.
Frequently Asked Questions
Q: What is the maximum hole depth for YG DTH drilling equipment?
The YGS series handles depths up to 30 meters depending on rock conditions. For deeper holes, YG offers extended drill rod packages. Contact us with your depth requirement.
Q: What compressor do I need for the YGS180?
The YGS180 works with a compressor delivering 10-15 m³/min at 7-10 bar. This matches most standard quarry compressors. YG can advise on matching if you share your existing equipment specs.
Q: Can the DTH rig machine drill at an angle?
Yes. The YGS series drills vertical, horizontal, and angled holes. The highest horizontal hole height ranges from 2.8m to 3.6m across models. This suits bench drilling and slope work.
Q: How long does delivery take to Africa or South America?
Standard models ship within 25-30 days. YG handles export documentation and container loading. We provide shipping updates throughout the process.
Q: What spare parts should I stock for the DTH drilling equipment?
Keep drill bits, hammer parts, and hydraulic filters on hand. YG supplies a recommended spare parts list with each machine. We also offer a startup kit for new buyers.
