Air freight, express and sea freight with crating, weights and documents prepared by our export desk.
Quality control
Incoming inspection and dimensional checks against the original part number, photo confirmation before dispatch.
Kits & combined orders
Complete assembly kits and mixed orders with other machines to cut freight per unit.
After-sales
Fitment support, replacement on confirmed quality issues and paperwork for warranty claims.
Fitment and sourcing notes
Articulated trucks run in mud, gradients and continuous haul cycles, so the consumable list matters: brake discs, brake packs, drive shaft joints, suspension bushes, hoist cylinder seal kits, hoist valves, filters and cab glass. We quote these as scheduled kits so you can plan maintenance around production.
Provide the model, serial number prefix and the part number or photo of the worn component, and we will confirm availability with grade options and freight.
