ZM20 Mini Excavator: Flagship 2.0-Ton Compact Digger with Cabin Option
Heavy-Duty 25 kW Engine with Retractable Track & Boom Swing Technology
The ZM20 Mini Excavator is a flagship 2.0-ton class compact digger designed for heavy-duty earthmoving, deep trenching, commercial construction, and all-weather applications. Powered by a high-output 25 kW Changchai 390 3-cylinder diesel engine (with optional Kubota 902 for global markets), the ZM20 delivers massive breakout force, swift hydraulic responsiveness, and relentless performance on tough job sites.
Engineered with advanced productivity features—including optional Retractable Tracks, Boom Swing function, an enclosed Operator Cabin, and Air Conditioning—the ZM20 provides premium operator comfort and versatility under any site condition or extreme climate.
Key Performance Advantages
1. High-Output 25 kW Powerhouse & Kubota Option
Driven by a powerful 25 kW engine, the ZM20 offers maximum digging torque and superior hydraulic pump flow. For strictly regulated or premium-tier international markets, the ZM20 can be upgraded with a genuine Kubota 902 diesel engine.
2. Retractable Track & Boom Swing (Optional)
- Retractable Tracks: Allows the operator to narrow the undercarriage for tight gate passage and extend it to a wide 1,300 mm chassis total width for maximum digging and lifting stability.
- Boom Swing: Enables offset digging along walls, fence lines, and building foundations without repositioning the tracks.
3. Extended 2100mm Dig Depth & Working Reach
With a maximum 2,100 mm digging depth, 3,150 mm digging radius, and an elevated 2,690 mm digging height, the ZM20 easily completes heavy utility trenches, deep pool foundations, and high-sided dump truck loading (1,780 mm dumping height).
4. All-Weather Cabin & Air Conditioner Options
For year-round operating comfort in freezing winters or scorching summers, the ZM20 can be equipped with a fully enclosed, sound-insulated Operator Cabin and an integrated Air Conditioning (A/C) system.
