Medium/Large Excavator

Main Pump: Dual-pump configuration with a compact overall structure and easy control. Flange mounting allows direct installation, saving space, while a complete matched component set shortens commissioning time. Different system types are adopted according to operating characteristics of machines with different tonnages. All products feature lightweight design, making the host machine more compact. Main Control Valve: The valve integrates swing priority, travel straight-line control, and flow regeneration functions. An integrated valve body reduces flow path pressure loss, improving energy efficiency. Swing System: Built-in mechanical brake, relief valve, make-up valve, and anti-reverse valve. Supports bidirectional rotation, with a mounting flange that can be directly connected to the gearbox ring gear. Based on proven technology, it is optimized for lighter weight and higher compactness, delivering increased output power.
