The HX300SL manages demanding excavation projects including large-scale highway construction, bulk earthmoving for commercial developments, and mining support operations where maximum bucket capacity and digging forces enable efficient material handling in compacted soils and fractured rock formations.
The Intelligent Power Control (IPC) system automatically adjusts engine and hydraulic output based on workload demands, with selectable modes optimizing performance across applications. The excavation mode reduces pump flow through lever control during precision grading work, minimizing fuel consumption while maintaining adequate hydraulic response for positioning movements.
The attachment flow control option provides independent pump management for hydraulic breakers and crushers, with pre-programmed settings for ten breaker types and ten crusher configurations. This eliminates manual flow adjustments when changing attachments, reducing setup time and preventing hydraulic system damage from incorrect flow settings.
The optional Advanced Around View Monitoring (AAVM) system provides comprehensive site visibility through nine camera views including 3D bird’s eye perspective and split-screen displays. The Intelligent Moving Object Detection (IMOD) feature alerts operators to personnel within 5 meters of the machine, essential for safety in congested construction sites and active mining areas common across Southern African projects.
The three-layer stacked cooling module increases heat dissipation while simplifying cleaning procedures critical in high-dust environments. The enlarged air inlet with protective grill prevents foreign material penetration without restricting airflow, maintaining cooling performance during extended operation in elevated ambient temperatures typical of Southern African summers.
The cab suspension mount utilizes coil spring and damper assemblies to reduce operator fatigue during extended shifts, while the optional swing lock system maintains stability when swing movement requires limiting, improving operating speed and precision during repetitive truck loading cycles.
Consider the HX300SL if your operations involve large-scale earthmoving requiring maximum bucket capacity, demand superior fuel efficiency across varied applications, or operate multiple shifts where advanced diagnostics and remote monitoring reduce unplanned downtime and maintenance costs.
High-capacity excavators deliver the substantial power outputs and enhanced hydraulic systems required for large-scale earthmoving, mining support operations, and demanding infrastructure projects. The Hyundai HX300SL produces 183 kW (245 HP) net power through its Hyundai HM8.3 engine, achieving bucket capacities to 1.85 m³ with advanced intelligent power control systems. We supply the HX300SL throughout Southern Africa with comprehensive technical support and regional parts distribution.
This 30,200 kg excavator suits contractors managing major infrastructure developments including highway construction, large-scale mining operations, and commercial site preparation where maximum productivity and fuel efficiency determine project economics and competitive advantage.
The Hyundai HM8.3 engine delivers maximum torque of 124 kgf·m at 1,300 rpm with power boost capability reaching 198 kW (265 HP) at 2,000 rpm during demanding applications. Fuel consumption averages 22-28 liters per hour under typical excavation loads, with the 500-liter tank supporting extended operation between refueling.
The hydraulic system delivers 2×285 L/min combined pump flow at 350 bar standard implement pressure, with power boost increasing boom, arm, and bucket circuit pressure to 380 bar for enhanced digging performance in difficult materials. The swing circuit operates at 300 bar with automatic brake and planetary gear reduction providing 12.2 rpm swing speed.
