Release Date: September 14, 2026
Recently, SADIVO Heavy Industry has completed full performance commissioning of its first customized SD230 15m long reach excavator and officially released it to the market. Targeting the pain points of conventional long reach excavators such as unstable operation, insufficient digging depth and poor working condition adaptability, this model features comprehensive upgrades to boom-arm assembly, undercarriage, power system, hydraulics, protection and operator cabin configurations. Specially developed for river construction and river dredging, it delivers stable, efficient customized construction solutions.
Long Reach Arm System
The arm assembly is fabricated from high-strength alloy steel plates, with key sections thickened and reinforced by built-in full-weld reinforcing bulkheads for superior structural strength. Pins adopt double hardening treatment of quenching and tempering, featuring strong torsion resistance and fatigue resistance to avoid deformation or cracking under heavy loads. It comes standard with a 1.2m³ large-capacity bucket, and a dredging bucket is available as an option. Pre-assembled pipelines enable convenient installation. Its working radius and digging depth far exceed standard-arm excavators.
Undercarriage System
Equipped with reinforced heavy-duty undercarriage and Hangang track components. Drive wheels, track rollers and carrier rollers are hardened for outstanding wear resistance. The standard 800mm-wide, 10mm-thick reinforced track shoes provide large ground contact area and low centre of gravity, effectively preventing tipping and shaking during long-reach operation. It improves operational safety under river conditions, extends the service life of travelling assemblies and reduces maintenance costs.
Power System
Powered by Cummins 6BTA5.9 6-cylinder engine with 5.9L displacement, rated power 133kW (180 HP). It delivers ample and stable power output, balancing heavy-duty performance and excellent fuel economy. Capable of continuous high-load operation, it adapts to complex river construction environments.
Hydraulic System
Adopts Korean Kawasaki FLUTEK K3V112DT main pump, matched with imported Korean control valve and swing motor. The complete set of core hydraulic components ensures reliable performance. Fitted with oil-water separator to keep oil circuit clean. It features fast response and even flow distribution for smooth and delicate compound movements. Precise and stable control is maintained even at the maximum extension of the 15m long arm.
Filtration System
Equipped with full set of Donaldson filters from the USA, providing multi-stage filtration for air intake, fuel and hydraulic oil circuits. It fully protects engine and key hydraulic parts, lowers failure risks, extends machine service life, cuts maintenance expenses and boosts equipment availability rate.
C38 Cabin System
Built with high-strength sealed structure and panoramic tempered glass for unrestricted field of view. It is fitted with high-definition LCD instrument panel, air suspension seat and intelligent pneumatic shock absorption system to adaptively buffer machine vibration and ease operator fatigue. Excellent noise reduction, dustproof and heat insulation properties together with tight sealing create a comfortable and safe working environment.
Comprehensive configuration upgrades endow SADIVO SD230 long reach excavator with great stability, high efficiency and durability. Perfectly suited for various river construction scenarios, it holds prominent competitive advantages among similar customized excavators.
Going forward, SADIVO Heavy Industry will continue to focus on R&D of customized construction machinery. Centered on the operational demands of river projects, we will support efficient and safe construction of domestic and overseas projects with high-quality equipment and complete after-sales services.
