Two catalog entries for XCMG QY70K brake disc sets can appear in the same search. One is listed as an eight-piece brake disc set; the other is a seven-piece brake disc set. The catalog identifies Set 02 as seven pieces, but a listing title is not a packing list. Ask for the current product reference and a written contents list before ordering either set.
A count might describe individual discs, the pieces in one package, or the combination shown in a photo. Ask the supplier to say which one it means. If an offer covers multiple kinds of pieces, request an itemized description rather than a single total. Have the workshop confirm which assembly is being repaired and whether the service documentation calls for specific references. Never add or remove pieces to make a set match an expected quantity without technical approval.
Keep the machine serial, assembly identification and original references together. If the machine has a history of brake work, the previous invoice may show what was ordered, not what is currently fitted. Label the invoice accordingly. A technician can identify the applicable configuration and any relevant replacement requirements; the buyer should record that determination rather than derive it from a parts listing.
Start with the offered number, confirmed contents and destination on the machine. Put those details on a quote comparison sheet before comparing prices. If one seller quotes a complete set while another prices individual items, ask each to state the quantity per pack and the number of packs needed to meet the approved requirement. Do not assume two sellers use “set” in the same way.
A practical inquiry can read: “Please quote the brake disc set for the attached assembly reference. State the item number, exact count per pack and the items supplied. Please confirm which count applies to the current offer.” This gives the seller a specific discrepancy to resolve. If the catalog description changes, keep the confirmation with the purchase order so the receiving team does not rely on an earlier screenshot.
Compare the delivered label with the approved order and have the relevant team check the package contents under the site’s receiving procedure. If the delivered count differs, record the package reference and the discrepancy before sending the parts to the workshop. A box with the expected number of pieces can still contain the wrong parts. The receiving record should therefore capture both the physical count and the identity shown on the supplied documentation.
If the buyer is stocking crane brake parts for several machines, assign each pack to the verified assembly reference rather than a bin named only “QY70K brake discs.” Keep the supplier’s confirmation where stores can find it. That is especially useful when a partially used pack returns from a job or when several similarly named sets arrive together. Installation and brake acceptance remain the responsibility of qualified personnel using the applicable service information.
No. Confirm the machine and assembly, part references and full set contents. A piece count helps check an approved order; it does not approve a substitute.
For a mixed fleet, keep a photograph of the confirmed set label with the vehicle’s repair history. If a later order repeats the old part number, check that it is for the same assembly and that the job scope has not changed. A repeat order is a chance to reuse verified information, not to skip the identification step.
Ask the supplier to put the confirmed pack count on the quotation and the packing list. If the order is split, record which line has arrived and which is still outstanding. This keeps an incomplete delivery from being counted as a complete set at the service bay.
Put the approved pack quantity on the crane parts packing list. At delivery, use the receiving inspection to record units received and units accepted separately.
