Heavy-duty lifting frames intended for crane lifting and offshore transfer are engineered as lifting equipment: rated lifting points, load testing and certification under LOLER, supplied with the test records. Units designed for fork handling are work equipment under PUWER and are marked for that use — the distinction is made at design stage, not on site.
Validation covers load testing, dye penetrant testing, non-destructive examination of welds and inspection reporting against a defined test plan, with finite element analysis used to prove the design where the load case warrants it.
Documentation extends to material certificates, weld procedures, inspection reports and test plans, traceable to the welder and the material batch. Identification is marked as standard — serial number, purchase order reference, TARE weight and working load limit — and units are UKCA marked where applicable. Manufacture is in Uttoxeter, Staffordshire.
