1. New Power: Efficient and Robust Yanmar Engine
The R57 PRO is powered by a high-performance Yanmar 4TNV98C/4TNV94L engine, known for its reliable power delivery, high combustion efficiency, and environmentally friendly emissions. This engine provides the strong, stable power foundation necessary for demanding cycles while focusing on fuel economy.
2. Fuel Efficiency via Fully Electronic Hydraulics
A key innovation is the fully electronic hydraulic system. By electronically controlling the main pump and main valve, the system achieves precise hydraulic output matched to real-time workload demands. This intelligent system reduces energy waste, resulting in a claimed reduction in fuel consumption of up to 7% compared to traditional systems, offering significant long-term cost savings.
3. Durable and Reinforced Structure
Built for longevity in tough conditions, the R57 PRO features a reinforced chassis and strengthened boom and arm. Critical structural components utilize high-strength wear-resistant steel plates, and key welds are minimized through integrated casting designs (e.g., boom bottom plate) to avoid stress concentration and improve overall durability.
4. Operator-Centered Comfortable Cab
The cab is designed with the operator's well-being as a priority. It features significant noise and vibration reduction, a standard air conditioning system, and an adjustable anti-vibration seat. The multifunctional electronic instrument panel provides comprehensive machine data, fuel consumption management, and maintenance reminders.
5. Convenient Maintenance Design
Serviceability is enhanced with strategically placed components. The engine filters and other maintenance points are centrally located behind the cab for easy access. Additional features like a battery disconnect switch, a foldable windshield for ventilation, and a reliable, reinforced counterweight bracket all contribute to easier and safer daily checks and servicing.
6. Exclusive RIPPA Care Support
RIPPA supports the R57 PRO with its "RIPPA Care" program. This includes nationwide sales and service network support, technical training on operation and post-processing system (DPF) maintenance, and services like fuel/urea quality testing to ensure optimal machine performance and longevity.
