Product details

1. Rotary Drilling Bit – Versatile & Durable

The rotary drilling bit is the core of the entire pile foundation equipment. Our bits are designed to handle soft soil, hard rock, and mixed strata with high efficiency. Manufactured from wear-resistant alloy steel, they offer long service life and fast penetration rates. The modular design allows the Kelly bar drilling rig to quickly adapt to changing ground conditions, minimizing downtime.

2. Hydraulic Outriggers – The Foundation of Stable Operation

Overall machine stability starts with the hydraulic outriggers. Our equipment is equipped with independently controlled hydraulic outriggers that provide a wide support base even on uneven terrain. The hydraulic system enables precise pressure control, allowing the operator to level the machine quickly. During deep-hole drilling or high-torque operations, the rotary drilling rig remains exceptionally stable, effectively reducing structural stress and improving drilling accuracy.

3. Hydraulic Hoses – Reliable Power Transmission

Continuous operation under harsh conditions relies on high-quality hydraulic hoses. We use multi‑spiral high‑pressure hoses that offer excellent resistance to abrasion, extreme temperatures, and hydraulic oil aging. The hose layout is optimized to reduce friction and facilitate easy inspection and maintenance. A leak‑free hydraulic system not only enhances operational efficiency but also lowers total cost of ownership—a key value point that users of heavy‑duty drilling equipment highly appreciate.

4. Cab – Ergonomic Operator Space

The cab serves as the control center of the machine, combining safety with operational convenience. It features a ROPS/FOPS certified structure, providing excellent visibility, along with an adjustable seat and an intuitive touchscreen panel that displays real‑time drilling parameters, hydraulic system pressure, and chassis tilt angle. The low‑noise design and automatic climate control effectively reduce operator fatigue during long working hours, contributing to overall job‑site efficiency. The integrated electronic control system also supports remote diagnostics, making this rotary drilling rig a smart choice for fleet managers.

Customer feedback

1. Reliable performance in tough ground conditions

“We’ve been using this rotary drilling rig on a bridge foundation project with mixed layers of soft soil and hard rock. The rotary drilling bit cut through efficiently, and we barely had any downtime switching between augers and core barrels. The hydraulic outriggers kept the machine perfectly level even on uneven riverbank terrain. A solid piece of pile foundation equipment.”

— Project Manager, Indonesia

2. Stability and precision that save time

“The independently controlled hydraulic outriggers and stabilizer legs give us confidence when drilling deep holes near excavation edges. The hydraulic system responds smoothly, and the cab’s touchscreen shows real-time tilt and pressure data, so our operators can adjust instantly. This heavy-duty drilling equipment has improved our drilling accuracy by a noticeable margin.”

— Fleet Owner, Philippines

3. Built to last with easy maintenance

“After two years in a high-temperature, high-dust environment, the hydraulic hoses still show no signs of wear or leakage. The multi‑spiral hoses and well-organized layout make daily checks quick. Low total cost of ownership is exactly what we look for in a Kelly bar drilling rig.”

— Equipment Manager, Saudi Arabia

4. Operator-friendly cab boosts productivity

“Our operators used to get fatigued easily on long shifts, but the low‑noise cab and automatic climate control on this urban construction drilling machine make a huge difference. The ROPS/FOPS structure gives them peace of mind, and the remote diagnostics help our maintenance team catch issues early. It’s a rotary drilling rig for sale that we’d buy again.”

— Construction Company, Brazil

Applicable scenarios

1. Bridge & Highway Foundation Construction

Our rotary drilling rig is widely used in bridge piers, elevated highways, and overpass foundations. Equipped with an Eaton hydraulic motor and overpressure protection device, it delivers stable torque even under variable loads. The carbide-tipped drill bit ensures smooth penetration through hard rock layers, while the clean borehole with no soil residue speeds up subsequent rebar cage installation and concrete pouring.

2. Urban High-Rise Building Piling

In space-constrained city sites, the rig’s compact design and simple operation allow quick mastery of the excavator-mounted rotary drilling attachment. The independently controlled hydraulic outriggers provide a stable working platform even on uneven ground, minimizing vibration impact on adjacent structures. Clean boreholes reduce secondary cleaning work, improving overall project efficiency.

3. Railway & Transmission Tower Foundations

For linear infrastructure projects such as railways and power transmission towers, the rig offers high mobility and rapid setup. The overpressure protection device safeguards the hydraulic system during intermittent high-torque drilling, ensuring reliable performance across scattered work sites. The alloy teeth on the drill bit maintain excellent wear resistance, reducing bit change frequency.

4. Soil Nailing & Anchoring in Slope Stabilization

When working on slopes or excavation faces, the rig’s hydraulic outriggers and stabilizer legs provide the necessary balance. The intuitive control system enables operators to become proficient quickly with the excavator-mounted rotary drilling attachment, making it ideal for anchor hole drilling and soil nailing applications. The clean hole wall ensures accurate grouting and anchoring force.

5. Renovation & Foundation Reinforcement Projects

In old city renovation or foundation reinforcement scenarios, the rig’s compact size and precise control allow operation in confined spaces. The Eaton hydraulic motor with overpressure protection ensures safety during complex drilling conditions, while the carbide-tooth bit easily breaks through existing concrete or mixed fill layers. Clean boreholes minimize environmental impact and speed up project completion.
