Three fields is all the form needs: who you are, how we should reply, and what you need to lift. If you would rather talk it through, Zalo and WhatsApp reach us fastest during Chinese working hours.
If you are replacing an existing crane, a photo of the nameplate is worth a page of description — send that and we will identify what you have.
Crane type, capacity (t), span (m) and lifting height (m) is usually enough for us to quote. Send a photo of your workshop if you are not sure.
