High-penetration grab designed for dense silt and alluvial sediments in Santos and Rio de Janeiro port constructions.
Trenchless design optimized for urban utility pipe laying in densely populated metropolises like São Paulo.
Advanced hydraulic continuous wall system offering exceptional verticality control for deep urban foundations.
Refurbished, field-tested heavy piling rig capable of running large interlocking Kelly bars for hard rock geology.
Brazil's geomorphology presents diverse foundation engineering challenges. Geotechnical engineers must navigate the highly variable tropical soils of the Central Plateau (Brasília red clay), the coastal muds of São Paulo state (Baixada Santista), and the deep basalt strata of the Southern region (Paraná Basin).
With the revitalization of federal infrastructure funding under the **Novo PAC (Program of Growth Acceleration)**, major civil projects such as subway expansions in São Paulo and Salvador, deep-water port expansions in Itajaí, and complex highway viaducts demand larger pile diameters and deeper drilling capabilities. Kelly bars, serving as the central transmission element of rotary rigs, must bear extreme torsional stresses and impact loads.
Sinovo Heavy Industry delivers specialized friction and interlocking Kelly bars engineered to withstand these dynamic geological profiles. By utilizing imported high-yield alloy steels and precise keyway thermal processing, we ensure minimal wear and optimal power transmission from the rotary drive to the boring tools.

| Feature / Spec | Friction Kelly Bar | Interlocking Kelly Bar | Brazil Soil Applicability |
|---|---|---|---|
| Torque Transmission | Via friction contact plates along keyways | Via mechanical locking pockets (dog-houses) | Friction for soft sands; Interlocking for hard stone |
| Max Drilling Depth | Up to 110 meters (Telescopic design) | Up to 80 meters (Thicker wall tubes) | Friction enables extreme depth in alluvial basins |
| Steel Tubing Grades | High-tensile alloy steel (Germany/China origin) | Thick-walled 25CrMo4 alloy steel tubes | Toughness optimized to handle vibration in basalt |
| Maintenance Profile | Low wear, easy slide inspection | High stress points require lock-pocket inspection | On-site welding guidelines provided by Sinovo engineers |
We implement state-of-the-art induction heating processes on all guides and keyways to optimize surface hardness up to HRC 50-55, minimizing metal-to-metal wear.
Equipped with high-performance polyurethane damping elements and heavy steel springs at base segments to absorb impact loads from hard rock rotary drilling.
Direct-match designs compatible with major global rotary piling rig brands (Sany, Bauer, Soilmec, Casagrande, IMT, XCMG) utilized across South America.
Our mechanical engineers review boring logs and soil reports from your Brazil site. We custom-configure the Kelly bar length, section thickness, and outer diameter to match your rig’s torque curve.
All materials undergo strict non-destructive testing (NDT) to prevent downhole tube rupture. Shipping pipelines to Santos and Paranaguá are managed smoothly with complete customs documentation.
We provide standard 12-month warranties. In the event of extreme abrasive wear, we provide replacement components and step-by-step welding procedures to restore keyways without compromising pipe integrity.
