FAQ
Q: What exactly is "true zero tail swing" on the U20, and how does it differ from short tail swing models?
A: True zero tail swing means the counterweight and cab platform rotate entirely within the machine’s track width — at all angles of rotation, no part of the machine extends beyond the outer edge of the tracks. On the U20, the overhang is zero; operators can position the machine against walls or structures and rotate freely without clearance calculation. Short tail swing competitors retain minor rear overhang and cannot work in ultra-confined spaces the same way.
Q: Is the Yuchai U20 suitable for indoor renovation and tight-access residential jobs?
A: Yes, with the appropriate configuration. The U20 features a telescopic chassis that narrows for narrow gateways, plus a swiftly detachable canopy to reduce overall height. Standard rubber tracks protect finished floors and paving. Zero tail swing eliminates collision risks in wall-bound work areas. For indoor load-bearing demolition, our technical team can supply ground contact pressure data to verify floor capacity.
Q: What advantages does the U20’s telescopic chassis bring to daily operation?
A: The U20’s adjustable telescopic undercarriage retracts to a narrower width to pass through gates and narrow passages, then extends outward to boost stability during digging. Combined with compact overall dimensions, it balances transport convenience and working stability — a key advantage compared to fixed-width mini excavators within the same weight class.
Q: What container configuration is used for export shipping of the Yuchai U20?
A: A single U20 fits neatly inside a standard 20-foot container without oversize width restrictions. For bulk volume orders, multiple machines can be arranged inside 40-foot containers with optimised stacking and angled loading layouts to maximise CBM utilisation and cut landed cost per unit. Contact our logistics team for custom loading plans and destination port freight estimates.
