Industrial grade machinery designed for deep foundations, underground structural engineering, and geological exploration projects globally.
Rotary bored piling remains the cornerstone of modern heavy civil construction. When structural designs load colossal stress on alluvial, marine, or variable rock bases, deep bored foundation piles transfer the loading structurally down to stable geological formations. High-torque hydraulic drilling rigs are engineered to manage these variables, utilizing telescoping friction or interlocking Kelly bars to transmit high-axial and rotational forces deep within the earth's crust.
The efficiency of a rotary drilling rig is predominantly measured by its effective torque, hydraulic flow capacity, and pull-down force. During deep foundation drilling, the kelly bar experiences complex shear stresses and compressive loads. Interlocking Kelly bars mechanical lock to apply positive hydraulic crowd force directly to the boring tool, which is crucial for drilling hard formations with an Unconfined Compressive Strength (UCS) exceeding 50 MPa. In contrast, Friction Kelly bars rely on frictional resistance between telescoping sections, making them faster and more efficient in soft clays, silts, and sand deposits where high crowd force is secondary to rotation speed.
| Rig Category | Torque Range (kNm) | Drilling Diameter (mm) | Max Depth (m) | Primary Geological Suitability |
|---|---|---|---|---|
| Light Micro-pile (e.g. SK666) | 40 - 90 | 300 - 1,200 | 15 - 30 | Urban soils, clay, sandy gravels, micro-piling |
| Medium Rotary (e.g. TR60) | 60 - 160 | 500 - 1,500 | 30 - 50 | Medium hard rock, soft layers, municipal projects |
| Heavy Duty (e.g. XR360) | 280 - 360 | 800 - 2,500 | 60 - 95 | Hard bedrock, high-salinity coastal sediments |
SINOVO Heavy Industry coordinates a vast industrial supply cluster. By pairing regional metallurgical steel (providing high-strength manganese steel alloys for structural masts and Kelly bars) with localized production hubs in Beijing and Hebei, we deliver machinery designed for long service life under heavy cyclic loads. This industrial clustering is supported by partnerships with world-renowned component suppliers (including Rexroth hydraulic systems, Kawasaki main pumps, and Cummins powerhouses). Our Xianghe production base coordinates precision machining, heat treatment, and automated welding lines, resulting in highly reliable drilling machinery that costs up to 35% less than equivalent Western-manufactured equipment.

The SK666 Micro Pile Drilling Rig is a versatile engineering drilling machine that combines high efficiency, flexibility, and stability. It is specifically designed for large-diameter, high-precision drilling operations. Widely used in micro pile, photovoltaic hole, anchor bolt hole, casing hole, and blasting hole construction, it offers excellent geological adaptability and operational convenience, significantly enhancing construction efficiency and hole quality.
The hydraulic splitting machine utilizes high-pressure hydraulic oil as its power source, applying advanced oblique wedge principles to generate splitting forces ranging from hundreds to thousands of tons. This industrial-grade equipment can split massive boulders within seconds, efficiently separating hard ore from rock formations without the environmental impact of traditional blasting.
TR60 rotary drilling is a self-erecting rig, which adopts advanced hydraulic load sensing technology and integrates electronic controls. This structure is simple and compact, and provides reliable operation. It is suitable for drilling with telescopic friction or interlocking Kelly bars (standard supply) and CFA drilling applications (optional).
Designed for urban deep foundation pit support, soil nail wall support, and railway slope reinforcement. It is suitable for anti-floating anchor rods, pipe shed grouting in tunnel engineering, and down-the-hole vertical/casing composite drilling in complex formations.
Suitable for subway, highway, and bridge foundation reinforcement projects, as well as soft ground treatment. The rig handles multi-tube vertical/horizontal drilling (89-142mm diameter) and general rotary jet grouting operations. Equipped with a 3-ton crane arm, it reduces labor intensity during setup.
Modified from a heavy loader chassis, this piling machine is primarily used for small-diameter, shallow-depth foundation projects, especially suitable for drilling and installing utility poles, photovoltaic piles, and agricultural support frames.
Designed for water and gas dual-use. This multi-purpose machine is suitable for anti-floating anchors, slope support, high-pressure rotary spraying, tunnel grouting, submerged hole rock drilling, pit casing, core drilling, and steel pipe piling operations.
Features a high-power top impact system that achieves effective impact drilling without requiring an external DTH hammer or air compressor. With high torque and rotation speed, it provides rapid penetration in sand, pebbles, gravel, and sandy soil, preventing borehole collapse.
Designed to meet the narrow construction space requirements of front-line operators targeting 50-90mm hole diameters. The machine is compact, lightweight, and offers fast travel speeds and off-road mobility. It is suitable for static rock splitting and urban construction excavation.
