Rubber tracks are standard version. Rubber tracks and steel tracks can be Interchanged without support wheel.
Interchangeable
Two columns canopy → four columns cabin. The cab is interchangeable.
Full Pilot Control
More comfortable driving experience and smoother movement.
Various Attachments
More than ten types of attachments
Hydraulic hammers, buckets, quick change devices, wood grabbers, simple grab pliers clearing bucket, clamshell bucket, drilling tool, lawn mower, etc.
More than 40 key working conditions are applied, with a wide range of working conditions.

FAQ
Q: What engine is fitted on the Yuchai U18, and does it satisfy global emission standards?
A: The U18 is equipped with a Yanmar engine meeting Euro V / Tier 4 emission standards, complying with environmental regulations across Europe, North America and other international markets. Matched with Yuchai intelligent load-sensing hydraulic system, it delivers powerful performance while maintaining low fuel consumption for construction and landscaping tasks. Confirm local certification requirements for your region with our sales team.
Q: Is the Yuchai U18 suitable for narrow-site and indoor renovation projects?
A: Yes, with the appropriate configuration. The telescopic chassis can be narrowed to pass through tight gateways, and the swiftly detachable canopy reduces overall height for doorway access. Rubber tracks protect finished floors and pavement. Its compact dimensions make it ideal for confined working areas. For indoor load-bearing work, our technical team can provide ground contact pressure calculations on request.
Q: What benefits does the U18’s telescopic chassis bring to daily operation?
A: The telescopic undercarriage retracts to a narrower width for convenient transportation and passage through narrow openings, and extends to increase stability during digging operations. This design balances mobility and working stability, standing out among many fixed-track mini excavators within the same weight class.
Q: What container configuration is used for exporting the Yuchai U18?
A: A single U18 fits into a standard 20-foot container without oversize restrictions. For bulk orders, multiple units can be loaded inside 40-foot containers with optimised layouts to improve CBM utilisation and lower unit landed cost. Contact our logistics team for detailed loading plans and shipping quotations for your destination port.
