Testing
How a lifter is built and tested
In this industry a tube lifter is usually assembled from a vacuum generator, a filter, a vacuum hose, the lifting tube with its wear cover, the operator handle, the pad and a top swivel, which often carries a non-return valve, hung from a trolley. Production steps and factory test methods are not described on this page yet; they will be added once the factory has confirmed them in writing.
Buyers in every market ask for a per-unit test certificate matched to the serial number; whether one comes with your lifter, and what it records, is stated in the quotation.
| Item on the record | What it shows |
|---|---|
| Serial number and model | Which unit was tested |
| Working load limit | The rating the test confirms |
| Test load and method | How the load was applied |
| Working vacuum and alarm points | The vacuum reached and the alarm settings measured |
| Hold or controlled-descent time on power failure | How the unit behaves without power |
| Alarm test | That the warning works |
| Inspector's signature and date | Who tested it, and when |
