Rotary Borehole Hydraulic Drilling Machine

It's a portable down-the-hole (DTH) drilling rig designed for small borehole drilling in construction, energy, mining and other industries. Typical uses include geotechnical drilling, anchor and piling holes, exploration and water well drilling where an 80–100 mm hole is required.

Model SRQD100, hole diameter 80–100 mm, drilling depth ≥20 m, working air pressure 0.5–1.0 MPa, rotation speed 0–65 rpm, lift power 9600 N, motor power 4 kW, air consumption ≥7 m3/min. Dimensions: 2300 × 600 × 750 mm, weight 550 kg.

The rig is specified for holes 80–100 mm in diameter and a typical drilling depth of 20 meters or more depending on ground conditions, tooling and rig setup.

The rig uses a 4 kW motor. The DTH hammer requires compressed air: working pressure of 0.5–1.0 MPa and air consumption of at least 7 m3/min. Verify that your compressor can maintain those parameters under load.

Yes. The rig is designed with user-friendly controls and a simple structure so operators can start with minimal training. We still recommend reading the operator manual and following an on-site familiarization session.

Core components such as the pressure vessel, pump and engine are backed by a 1-year warranty against defects. Each machine is supplied with video outgoing inspections and a machinery test report to verify condition before delivery.

Regular maintenance includes checking and changing engine/motor oil and filters per the manual, inspecting and servicing the air system and hammer, greasing bearings and sliding parts, checking hoses and seals for wear, and replacing worn drill bits and O-rings. Follow the supplied maintenance schedule for best results.

Common consumables are DTH hammers, drill bits (button bits), drill rods, seals/O-rings, air filters and engine/motor filters. It's recommended to stock critical wear parts and a basic service kit to minimize downtime.

The rig is compact (2300 × 600 × 750 mm) and weighs about 550 kg. It can be moved with a small truck, trailer or forklift depending on site layout. Its size makes it suitable for confined sites and easier to reposition than larger rigs.

The rig is described as adaptable to a wide range of geological features. DTH systems are especially effective in fractured rock, medium-hard to hard rock and many consolidated formations. Very soft, unconsolidated ground may require different tooling or methods.

Use appropriate PPE (helmets, eye/face protection, hearing protection, gloves). Ensure the rig is level and secured, check air pressure and hoses for leaks before operation, follow lockout procedures for maintenance, and avoid loose clothing around rotating parts. Only trained personnel should operate and maintain the machine.

Rotation speed is variable from 0–65 rpm and the rig provides a high swing torque for efficient rock penetration. Actual penetration rates depend on rock type, bit selection, air pressure and operator technique.

Standard delivery content may vary by supplier. Commonly sold separately or as optional kits are DTH hammers, drill bits, drill rods and compressor packages. Contact the supplier to confirm included items and available accessory packages.

The machine comes with a test report and video inspection. For after-sales support, spare parts and technical guidance, contact the vendor or authorized service partner. They can provide maintenance advice, replacement parts and troubleshooting assistance.

Contact the manufacturer's sales team or your authorized dealer with your project requirements (desired hole diameter, depth, site conditions, and compressor availability). They can advise on configurations, accessories, lead time, pricing and delivery. Ask for the machinery test report and warranty details before purchase.
