Frequently Asked Questions
Short answers to the commercial and technical questions buyers usually ask before they compare suppliers.
Can you provide an MA certificate for every model?
Document status is checked against the exact model before quotation. Similar product names can have different certificate scopes and validity dates, so we confirm the model, certificate number, holder, and current status as one package.
What information is needed for a technical quote?
Send the model or equipment type, mine conditions, rail gauge or roadway size, voltage, required capacity, quantity, destination, and required document set. Photos, drawings, and an existing equipment nameplate are useful for replacement orders.
Can equipment be inspected before shipment?
Yes. The inspection plan can cover dimensions, nameplates, welds, operating functions, order configuration, document matching, packing, and loading evidence. Test items depend on the equipment category and contract.
