Lifting Gear Inspection

This is the accessory inspection: everything between the hook and the load. It is not the inspection of the lifting appliance, and it is not the plan for the lift. Using it for the crane or the racking produces a record that neither the statutory examination series nor the inspection round can read.

Lifting accessories sit in the most prescriptive corner of equipment inspection. The criteria for removal from service are written into the standards, the interval is set in law, and the outcome of a failure is specified rather than left to judgement.

This is one of the few areas where regimes converge on hard numbers. Every major jurisdiction requires periodic examination by a competent person, a legible rating on the item, and defective gear taken out of use; the differences are the interval and whether a report is prescribed.

The gear section repeats per item, and how the record is cut decides whether it is usable afterwards. Four calls determine whether an inspection can be traced to a physical object and whether a failure actually removes that object from use.

Lifting gear findings divide into two families: the item that should have been discarded and was not, and the record that cannot be tied to an item at all. The second turns a single missed sling into a fleet-wide problem.

A food plant maintenance team used four-metre webbing slings to lift agitator shafts out of process vessels during weekend cleans. The store held six identical two-tonne slings on one rail. Pre-use checks were recorded on a tablet, the item chosen from a pick list reading Sling 2t webbing with the same asset ID for all six. In March a fitter recorded Fail against cuts and abrasion, noted a nicked edge near the eye, and left the sling on the bench for the supervisor. Destroyed stayed at No, still in service, because he did not scrap things.

Someone tidying the workshop put it back on the rail on Monday. It was used in April and in May. On the second June lift the sling parted at about sixty per cent of its working load limit and a 180 kilogram shaft dropped two metres onto the vessel platform. Nobody was underneath. The investigation found the March fail, and a second fail recorded in April by a different fitter with the same detail, on the same asset ID, on what all assumed was a different sling.

There was no way to know whether the March fail, the April fail and the June failure were one sling or three, because the six shared an identity. The team had recorded the defect twice and still could not act, since acting meant picking one item off a rail of six that looked the same. The corrective actions were individual marking and registration of every accessory, a knockout blocking submission where a Fail leaves Destroyed unanswered, and a scrap bin only the store keeper could reach.

The form is a condition check. What fails around it is identity and disposal: gear that reached the rack without a register entry, an interval sitting in a spreadsheet nobody owns, and a failed item nobody was accountable for cutting up.

KnowSafe

Holds the accessory register per site, drives the pre-use and periodic inspections from it, and blocks a failed item returning to in-service without destruction evidence.

KnowMaintain

Carries the examination interval on each asset so the six-monthly falls due against the item rather than a calendar, and shows what is out of date before it is used.

Ella

Watches for the combination that matters, a Fail with destruction unconfirmed, and raises it with an owner and a same-day deadline instead of letting it sit in a completed record.

KnowContractor

Collects examination reports for hired and contractor gear at mobilisation and registers those items for the duration, so borrowed equipment is inspected on your cycle.

Lifting accessory

Equipment used to attach a load to lifting machinery: slings, chains, hooks, shackles, eyebolts, rings and below-the-hook devices. It carries the shortest statutory examination interval.

Working load limit

The maximum mass the accessory is rated to support in a specified configuration, marked on the item. Not a single figure across all modes of use.

Thorough examination

A systematic examination by a competent person, at a defined interval, sufficient to detect defects that are or may become dangerous, giving a report with prescribed particulars.

Mode factor

The multiplier applied to a sling's rated capacity for the configuration used: vertical, choked, basket and multi-leg arrangements at stated angles.

Discard criteria

The numeric and observable conditions at which an item must leave service: broken wire counts, link stretch, throat opening increase, cut load-bearing stitching.

Shock load

Sudden dynamic loading from snatching, dropping or arresting a load. It can exceed the rated capacity without visible damage, and triggers examination before further use.

Proof test

A load test above the working load limit applied before first use or after repair, evidenced by a certificate rather than an inspection record.

Colour coding

A tagging convention showing which examination period an item is current for. An aid at the hook, not evidence the examination happened.
