The first aerial lift met your expectations. You are ready to buy more from the same Chinese supplier and say, “Make the next batch the same as last time.”
But “last time” could mean the original quotation, a configuration changed during production or the final version you accepted.
Before increasing the order, turn the first machine's accepted configuration into an explicit baseline. Then check batch differences and individual delivery records. A shared model name cannot replace those steps.
1. Establish which version the factory should reproduce
Consider a hypothetical example.
The first order began with configuration V1. During production, both parties approved a charger substitution. The final machine was supplied as V2 with the corresponding manual. Satisfied with that version, the buyer orders six more machines of the same model.
If the new order refers only to the original quotation, production may still see V1. If it says only “same as the first unit,” staff have to search old messages to find the final decision.
A clearer requirement is:
This batch is based on the first machine's final accepted configuration V2. Approved changes and the document list form part of the order attachments. Any planned difference must be submitted for approval under the agreed process.
Separate what must remain unchanged, improvements arising from first-unit feedback, and permitted differences. Documents in different languages for different destinations, for example, can vary if agreed in advance; they should not arrive as unexplained deviations.
Retain the conditions under which the first machine was evaluated. Satisfaction at one site does not establish suitability for every application.
2. Ask the factory to list differences—not just say “no problem”
Send the baseline to sales and ask them to coordinate a review by production, technical and documentation staff against the batch actually planned.
See the guide to approval of equivalent parts for the relevant checks.
For example:
Against the accepted baseline, please identify what remains unchanged, what you plan to alter and how first-unit improvements will be implemented. List anything unconfirmed separately. Please do not use “same model” as a substitute for configuration confirmation.
Accepted-machine-to-batch consistency checklist
| Item | First-unit acceptance basis | What to confirm for this batch | Verification records |
|---|---|---|---|
| Principal specifications and use | Final specification and confirmed operating requirements | Requirements to preserve and permitted differences | Applicable documents and agreed inspection results |
| Key configuration and versions | Final configuration and approved changes | Version to be supplied and how changes are submitted | Actual configuration and change references |
| First-unit improvements | Findings, corrective records and buyer feedback | Improvements included and how they will be checked | Implementation and verification evidence |
| Accessories and documents | Final delivery list and manual versions | Per-machine or shared quantities; languages and versions | Allocation list, documents and packing records |
| Machine identity and inspection | First-unit inspection scope and results | Identification of every unit and batch inspection plan | Serial-number list, inspected units and results |
Put the reference machine, new order, baseline version and approval date above the table; they need not be repeated in every row.
For accessories, state whether “one set” means one per machine or one for the entire batch. Compare prices on the same supply scope using the quotation comparison guide.
Where Chinese production instructions and the foreign-language order differ, resolve the meaning before execution. Completing a translation does not establish that production is using the same requirements. Models, versions, quantities and approvals still need to align.
3. Check an early unit from the actual batch
For larger or customised orders, agree a review of key configuration and first-unit improvements on an early completed machine from the batch.
The unit should come from the actual production run and use the batch's intended components and documents—not be a separately prepared display machine.
In the example above, finding a V1 charger on an early unit should prompt questions about why the production baseline was not updated and which later machines or purchased components are affected.
Resolve more than the one machine in front of you. Communicate the accepted version and corrective arrangements to the relevant teams, then adjust subsequent assembly or reinspection according to the actual affected scope.
An early check can expose repeated misunderstandings. It does not automatically approve the machines that are still unfinished. Complete the agreed pre-shipment inspection as planned.
4. Know each delivered machine's version and what was inspected
Batch records should let the buyer trace every unit's serial number, actual configuration version, approved differences and related inspection records.
Where all machines share a configuration, reference one common version. Where some differ, identify the affected serial numbers and approval records rather than duplicating identical information for every unit.
Distinguish individual traceability from individual inspection. Listing every serial number does not establish that every unit received the same checks. Inspecting one machine does not justify marking all machines as inspected.
If sampling is used, agree the lot, items, selection method, sample size and acceptance rules in advance. NIST describes acceptance sampling as a way to decide whether to accept or reject a lot using sample information, not as inspection of every item. A sample result does not mean each machine has been independently verified. NIST acceptance-sampling guidance
There is no fixed sampling percentage suitable for every aerial lift order. Requirements that legislation, manufacturer procedures or the contract specify for every unit still apply to every unit.
Finally, machine identity, configuration, accessory allocation and shipping documents should form a coherent record. Use the shipping-document cross-check guide for that handover. Continue using the same equipment records for maintenance and spare-parts enquiries.
A successful first purchase is a reason to develop the relationship. Converting that experience into an executable baseline gives the next batch clear production and verification requirements—not just confidence that the last order went well.
The first machine is accepted, but the larger order's requirements are still unclear?
Send Levantis the final first-unit configuration, or the original quotation together with approved changes, and explain the next batch's quantity and differences. We can help organise the acceptance baseline, confirm proposed changes with the supplier, and discuss production follow-up and batch checks for the actual order.
