Description
Shantui SE220 Medium Crawler Excavator
The Shantui SE220 is a highly versatile, high-efficiency 22-ton class medium crawler excavator designed to excel across municipal construction, highway engineering, civil earthworks, and standard quarry environments. Combining a dedicated large-displacement engine with a precisely calibrated, high-end hydraulic control setup, the SE220 optimizes throttle parameters to match real-time multi-functioning tasks smoothly—ensuring exceptional fuel economy, robust breakout forces, and lasting operational reliability.
Key Performance & Functional Highlights
- Reliable Power Plant: Powered by a premium 6-cylinder water-cooled, turbocharged engine outputting a rated 112 kW at 1950 rpm to manage sustained high-resistance workloads without stalling.
- Tier 2 / Stage II Emission Rating: Engineered with a robust mechanical or electronic fuel system framework designed for high tolerance across diverse regional fuel qualities while preserving strict international standard execution.
- High Digging Efficiency: Equipped with a standard 1.05 m³ optimal capacity bucket paired with a 127 kN bucket digging force, drastically increasing cycle speed and material movement per hour.
- Streamlined Serviceability: A wide-opening, backward-tilting engine hood gives immediate access to centralized filters located on the right-side door, making fluid level management, air filter replacement, and routine servicing effortless.

Advanced Hydraulic Flow Matching
The SE220 features dual axial variable piston pumps that put out a maximum discharge flow rate of 2×218 L/min. By utilizing an intelligent percentage throttle flow-matching system, hydraulic energy is prioritized directly to the boom or track drives depending on demand. This dynamic load-sensing response eliminates dead time during composite operations (such as sweeping swing and simultaneous dumping), achieving up to 11.5 r/min swing speeds securely under continuous duty cycles.
Robust Undercarriage & Reinforced Attachments
Built onto an exceptionally rigid cross-section X-frame, the crawler assembly features 47 track shoes per side with 8 track rollers designed to resist stress twisting over uneven, rocky ground. Key stress concentrations on the 5700 mm boom and 2925 mm arm are reinforced using large-cast thickened plates. This versatile structure effortlessly accommodates secondary attachments including hydraulic breakers, rippers, or compactors to match changing job requirements.
