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.

Road Rollers

Dual Pump Main Hydraulic System Features a compact dual-pump design for easy control, allowing direct flange mounting to save space. The pre-configured component set reduces debugging time. Customized for different roller models, offering both positive and negative flow control system options. All products are lightweight, contributing to a more compact machine design. Main Control Valve Integrates a swing priority valve, straight travel valve, and flow regeneration valve. The mono-block valve body design minimizes flow passage pressure loss, resulting in higher energy efficiency. Swing System Equipped with an internal mechanical brake, relief valve, charge valve, and anti-reverse valve. Supports smooth bidirectional rotation, with a mounting flange that connects directly to the reducer gear ring. Based on proven technology, the system has been optimized for lightweight and compact design while increasing output power.

Small Excavator

Flow-Sharing Load-Sensing Hydraulic System Better controllability and lower fuel consumption The system uses a flow-sharing load-sensing design for smooth operation, high efficiency, and reduced fuel use. The HP6V axial piston pump runs at 320 bar continuous pressure and supports electro-proportional power control, load sensing, and pressure cut-off, ensuring system safety and maximizing performance. Control modes include displacement, pressure, and torque control. The main control valve integrates functions like arm regeneration (except HVSE 09), anti-dive, boom lock, and travel synchronization. A spool-type pressure compensator enhances comfort and improves efficiency. The swing system has a compact design with mechanical brake and auxiliary valves, supporting bi-directional rotation. The mounting flange connects directly to the gearbox ring gear. Hydraulic oil lubrication lowers maintenance and operating costs.
