Frequently asked questions
What engine does the K-40 use?
The 4-ton K-40 is powered by a 37–55 kW diesel engine sized for full-load climbing and continuous duty. Chinese (Xinchai/Quanchai-class) and optional Japanese engines are available — tell us your preference.
Diesel, LPG or electric — which should I choose?
Diesel suits heavy outdoor work, rough ground and long single-shift runtime with no charging. For indoor/clean or low-noise duty, see our electric and lithium ranges. We can quote all three for the same load.
What is the minimum order quantity?
We ship from a single unit for sample/first orders; full-container (FCL) pricing gives the best unit cost. Ask for both single-unit and container quotes.
