Reach the export desk directly — tell us the truck or machine and we'll reply with a configuration sheet and a quote, not a generic brochure link.
Before you write
Include the vehicle or machine, the capacity or working width, your destination port and the emission standard your country requires. That's enough for us to put together a first configuration sheet and an FOB or CIF price, usually within 72 hours of your message reaching us. Not sure exactly which model fits your job? Browse the full product range before you write.
If you already have a spec sheet or a quote from another supplier, send it along — we'll price against it line for line rather than starting from a blank page, whether you're comparing a sewage suction truck or any other model in the range. If your market buys the body or working kit rather than a complete truck, say so up front and we'll quote it that way from the start.
Where we are
The factory is in Liangshan, Jining, Shandong, China. Export orders ship RoRo from Qingdao or Shanghai, with smaller units crated in a 40-foot flat rack where RoRo service to your port is thin.
If a factory visit fits your schedule, ask through the form below — Australian customers and a delegation from Korea have both visited Liangshan in person before ordering, and we're glad to arrange the same for you.

Frequently asked questions
How fast will I get a reply?
Configuration sheets and FOB or CIF quotes usually go out within 72 hours of your enquiry — sooner if the details in your message already answer the basics.
What documents do you prepare for customs?
Certificate of origin, commercial invoice and packing list are prepared for your customs broker with every export order, matched to the emission standard and drive side you specified.
Can I email instead of using the form?
Yes — write to [email protected] with the same details: vehicle or machine, capacity, destination port and emission standard. Either route reaches the same export desk.
