XCMG XE220GS Amphibious Excavator

Overview

The XCMG XE220GS is a 30.8-ton amphibious excavator for swamp, wetland, river, lake and coastal work. Its extended undercarriage, hollow pontoon structure and twin-row chain design give it very low ground contact pressure and safe travel in shallow water, with a maximum working water depth of 1.5 m.

XCMG positions the machine for soft-ground excavation, dredging, cleaning, land improvement and other duties where a standard crawler excavator would sink or lose traction.

Key Features

• Amphibious undercarriage: hollow pontoon structure, twin-row chain design and very low ground contact pressure for swamp and shallow-water travel.
• Extended working device: XCMG states that the new-generation working device is 30% longer, giving a 12,105 mm maximum digging reach.
• Long runtime: an innovative auxiliary fuel tank doubles volume, and an electric diesel pump transfers fuel quickly to the main tank.
• Higher stability: moving the counterweight rearward is stated to improve stability by 18%.
• Soft-ground capability: track contact area is 4–5 times that of a standard excavator.
• Service access: walkways around the turntable make maintenance easier.

Applications

Wetland excavation, swamp and soft-ground earthmoving, river and lake dredging, coastal cleanup, drainage-channel maintenance, land improvement and shallow-water construction.

A legacy XCMG page for the same model lists 229 kW engine power and leaves operating weight blank. That page conflicts with both the current page and the official brochure, which list 129 kW and 30,800 kg; the conflicting legacy values are not used.

Specifications follow the XCMG official pages and may vary by batch and configuration. Final configuration and figures must be confirmed after order placement.
