Rigging inspection covers the lifting accessories between the crane hook and the load: slings of wire rope, chain, and synthetic webbing, shackles, eyebolts, hoist rings, spreader beams, and lifting magnets. This gear fails more often than the cranes above it, it is handled, dragged, overloaded, and stored badly, and a failed sling drops the load just as thoroughly as a failed crane, which is why crane inspection programs that ignore rigging inspect the strong half of the system.
The criteria are concrete, from standards such as ASME B30.9 and EN 1492: wire rope slings rejected for broken wires beyond counts per lay length, kinks, crushing, or core protrusion; chain slings for wear beyond a percentage of link diameter, stretch, gouges, or cracks; synthetic web slings for cuts, holes, snags, broken stitching, chemical or heat damage, and any illegible tag; shackles for wear beyond roughly 10 percent of original dimension, bent pins, or opened throats. The phrase that matters: measurable limits plus destroy-on-rejection, rejected gear is cut up or destroyed, never left where a hurried rigger can reuse it.
A fabrication shop inventories its rigging for the first time in years: 118 items found, of which 31 have no legible tag, 9 fail measurable criteria (one chain sling stretched, two web slings cut, six shackles worn or mismatched pins), and 14 are undocumented purchases nobody can trace. Immediate outcome: 40 items destroyed, 78 tagged into a register with QR identifiers, and quarterly documented inspections scheduled. Cost: an inspector-day plus a few thousand in replacement gear. What it bought: every future lift in that shop now happens on gear with a known identity, rating, and history, and the next stretched chain gets caught at inspection instead of at 2 meters over a machine bed.
Rigging degrades between lifts: slings left under loads, web slings on sunlit hooks (UV), chains dragged across floors, shackle pins swapped with hardware-store bolts. The program therefore includes racks and hooks at point of use, chemical and heat exposure rules, and the quiet discipline of returning gear to storage, all trainable habits, and a natural Job Instruction breakdown for new riggers.
Fabrico gives every sling an identity and a memory: each item registered with its WLL, type, and ID, periodic inspections as recurring work orders with per-item pass/fail against the criteria, rejected items closed out as destroyed (with photo evidence), and the register always answering the auditor’s first question: show me this sling’s history. Pre-use checks stay human and fast; the documented layer stops depending on a binder in the rigging loft. EU-built, with EU data residency.
Annual documented inspection is the common regulatory floor, tightened to quarterly or monthly for severe service (high frequency, edge loading, chemicals, heat). Pre-use checks happen every lift regardless. Your standard, insurer, and service severity set the exact cadence, and the register enforces it.
Synthetic web slings: no, damage means destruction. Wire rope slings: effectively no for the rope itself. Chain slings: only by the manufacturer or a qualified repairer with proof testing and re-certification, in practice, most rejected gear is replaced.
At minimum the working load limit (per hitch configuration where relevant), material or grade, and a unique identifier tied to the inspection record. An illegible or missing tag is itself a rejection criterion, because an unrated sling cannot be used within its rating.
