Ordering Gunnebo Lifting Hooks? Run This 8-Step Checklist First

I have been ordering lifting gear for a fabrication yard since 2017—Gunnebo lifting hooks, shackles, swivel hooks, safety hooks, container lifting lugs, and everything else that connects a load to a crane or chain block. It sounds straightforward. In my case it was not.

Six significant ordering mistakes, roughly $11,500 in wasted budget. That number does not include the awkward conversations or the days lost waiting for replacements.

Every mistake had the same shape: something looked right on screen, got ordered, or got installed before we caught it. That is why I now maintain a pre-purchase checklist for our team. This version is for people buying Gunnebo hooks and rigging components in normal B2B quantities—maintenance planners, safety officers, workshop leads—not for engineered custom lifting designs.

Here are the eight checks we run before and after every order.

1. Write down what connects to the hook

Before you open a product page, answer three questions: what passes through the hook eye—a chain link, a shackle pin, a lug hole? Does the hook need to rotate, or must it stay in a fixed orientation? And does the application need a spring latch, a positive-locking mechanism, or no latch at all?

I learned this lesson in my first year. I ordered 40 swivel hooks for a job that called for fixed eye hooks. The word 'swivel' was on the purchase order, and my logic was simple: if a swivel can do everything a fixed hook can, it will work. Then it rotates when you do not want it to. That $1,900 lesson in return freight plus mornings of rework taught me to write the exact connection into the request before anyone hits buy.

2. Select by working load limit, not by body size

Most buyers focus on the throat opening and hook size and completely miss the working load limit. A larger-looking hook is not automatically a stronger hook. Alloy grade, heat treatment, and manufacturer design all matter.

The question everyone asks is 'What size hook do I need?' The better question is 'What WLL do I need, in what configuration, with what fittings at each end?' If the hook is going into a multi-leg sling with an angle factor, the hook rating alone is not enough. That is a lifting calculation, not a guessing game.

Gunnebo lifting hooks are often ordered as part of a full chain or rigging system. Keep the hook, chain, and shackle ratings in the same system. Mixing one underrated component into a matched set changes the whole assembly.

3. Buy the marking, not the product photo

Photos on a supplier website or a phone screen are not a specification. Angled shots hide latch orientation. Shadows hide permanent markings. The same product family can have several variants that look almost identical.

Ask the supplier: can you send a photo of the permanent marking on the hook you will actually ship? That request is reasonable. A good supplier would rather send one photo than process a return later.

Ten years ago, the range of hook styles in common use was smaller, and 'looks about right' worked more often than not. Today, with more grades, more latch styles, and more manufacturers in the market, that old shortcut does not hold. If the marking is not visible in the listing, it has not been verified.

4. Check metric and imperial dimensions with a caliper

Physical size can fool you in a photo. 12 mm and 1/2 inch look almost identical. 19 mm and 3/4 inch are nearly indistinguishable to the eye. But they are not interchangeable in a certified lifting system.

When you are ordering Gunnebo lifting components, match the chain size, pin diameter, and hook opening in the same measurement system. Never assume that because a pin slides through an eye, the component is correct. 'It fits' is not a safety argument.

Use a caliper, not a tape measure, and check the actual component you are connecting to. If a hook needs to be filed, ground, or forced to fit, stop. You do not modify lifting hardware to make it work; you replace it with the right item.

5. Confirm certificates and traceability before the PO

Ask three questions in writing at the quote stage. Does the order include a manufacturer certificate or test certificate? Does the certificate reference a batch or lot number that appears on the hook? And which standard does the component meet?

This step is easy to skip because it feels administrative. I skipped it once with a supplier we had used for two years. In September 2022, the batch certificate was not available for one order, and tracing it after delivery cost roughly $900 in admin time and expedited freight. The hooks were probably fine. The paperwork was not, and paperwork is part of the product.

Certificate requirements vary by country, customer contract, and application. The point is not to demand the heaviest document package on every small order. The point is to confirm what is included before payment, not to chase it after arrival.

6. Inspect the first piece before unpacking the whole delivery

When goods arrive, compare the packing slip and product code with the PO. Then take one item out and check it before you cut open every bag and dump everything into a bin.

Check the permanent marking. Check that the latch opens, closes, and holds. If it is a swivel hook, confirm that the swivel actually rotates. If it is a fixed hook, confirm that it does not rotate. A 30-second sample check would have caught most of the mistakes I made in my first five years.

Oh, and one important nuance: if paint or rust hides the marking, clean the area with a brass brush or a suitable solvent. Do not grind the hook body with power tools just to reveal a marking.

In the 18 months after we standardized this incoming check, we caught 17 discrepancies before they hit the shelf. Some were supplier typos. A few would have been very awkward if they had reached the workshop.

7. Register each piece before it goes into stock

Create one register line for each item, or at least for each batch. Include date received, item description, working load limit, certificate number, batch number, and storage location. That sounds like office work, but it prevents a specific and common failure: two visually similar hooks with different ratings ending up in the same drawer.

Gunnebo hooks intended for different chain sizes can look similar from a distance. If they are stored together without separate labels, someone will eventually grab the wrong one. Separate them physically and make the register the place where the identity is recorded.

Do not paint over markings. Do not weld or stamp your own ID into load-bearing surfaces unless you know exactly what you are doing. Use tags, bins, and register entries instead.

8. Put pre-use checks and quarantine in the same procedure

Pre-use checks are not only for old equipment. New hooks can arrive with latches that do not seat, swivels that do not turn, or markings that do not match the invoice. Before a hook goes into service, look for: cracks, stretched or deformed hook openings, corrosion, pitting, a latch that does not stay closed, and markings that are no longer readable.

Our yard uses red 'DO NOT USE' tags. If anything fails a check, tag it immediately and move it out of general stock. If something is suspicious but you are not sure, treat it the same way. Suspicion is enough to quarantine.

This checklist is not a substitute for an engineer's review of a lifting plan. But it will stop the more common problem: the wrong component getting ordered, received, registered, and installed without anyone stopping to ask whether it is actually what the job requires.

The most expensive rigging mistake is the one that gets installed and then discovered weeks later. A caliper, a camera, and one email at the quote stage can prevent most of that.

An informed customer asks better questions. A better question, asked in the right order, is what a good rigging order looks like.
