The R140W-9S proves particularly effective in utility installation projects across Southern African urban development areas. Its compact dimensions combined with outrigger stabilization enable operation in restricted spaces while maintaining the 87.3 kN (8,900 kgf) bucket digging force necessary for trenching through compacted urban soils. The bucket capacity range of 0.23 to 0.71 m³ accommodates both precision excavation work and material loading operations.
The hydraulic system features dual variable displacement piston pumps delivering 2×130 L/min total flow with pressure settings optimized for different functions. The wet disc braking system on front and rear axles with automatic spring-applied parking brake ensures safe operation on sloped urban terrain. Maximum gradeability reaches 35 degrees (70%), handling the steep access ramps frequently encountered at infrastructure development sites.
Consider the R140W-9S if your operation requires frequent relocation between job sites, works primarily on paved surfaces or in urban environments, or needs the flexibility of wheel-mounted equipment combined with excavator capability. Operations focused exclusively on continuous excavation at single locations may find greater productivity in tracked excavator configurations.
Wheeled excavators deliver the mobility and flexibility essential for infrastructure development, utility installation, and urban construction projects. The Hyundai R140W-9S delivers 84 kW (113 HP) of gross power through its Cummins B3.9-C engine, handling diverse tasks across road construction, trenching, pipe laying, and material handling applications. We supply the R140W-9S to Southern African operations with comprehensive technical support and genuine parts availability from our regional network.
This 13,700 kg wheeled excavator excels in applications requiring frequent relocation between work sites and operation on paved surfaces. The machine’s design addresses the unique demands of urban construction environments while maintaining the digging capability necessary for utility excavation and site preparation work.
The Cummins B3.9-C turbocharged, charge air cooled, direct injection engine produces 84 kW gross power at 2,100 rpm with 330 lbf·ft (45.6 kgf·m) peak torque at 1,500 rpm. The engine’s 3,900 cc displacement features 40% fewer parts than competitive designs, simplifying maintenance requirements while meeting Tier 2 emission standards without electronic engine controls.
The hydraulic system operates dual variable displacement piston pumps in a cross-sensing, fuel-saving configuration. Implement circuits operate at 350 kgf/cm² (4,970 psi) with power boost capability to 380 kgf/cm² for boom, arm, and bucket functions. The 210-liter hydraulic system capacity supports continuous operation with 5,000-hour hydraulic oil service intervals reducing maintenance frequency.
The carrier features constant mesh helical gear transmission providing two forward and reverse travel speeds. First gear delivers 8 km/h with 8,500 kgf maximum drawbar pull for working in soft ground conditions, while second gear reaches 30 km/h for road travel between sites. Standard dual 9.00-20-14PR tube-type tires provide flotation across varied terrain, with solid tire options available for applications involving sharp debris.
