Compare the same things: year, hours and how they were verified, condition of the travel system, hydraulics and tyres, attachments included, Incoterm, port of loading, and what the price excludes.

Ask us for the model, tonnage or destination you have in mind — we reply with matching units and an FOB or CIF quotation.
