Rigging is quoted fast when the enquiry is specific and slowly when it is not. “Shackle 1 inch” could be a 5.5 t commercial shackle, an 8.5 t G-209 or a 12.5 t alloy shackle; “3 t sling 4 m” could be a round sling, a webbing sling or a wire rope sling with any of a dozen end fittings. Each back-and-forth costs a day. This checklist covers what a supplier needs to quote the right item first time.

/03Documents and inspection.
- Certificate: the manufacturer’s test certificate comes as standard with rated items; say if you need anything more, such as a material certificate or a declaration of conformity — see lifting gear test certificates.
- Third-party inspection: if the site or client requires inspection by an approved third party before delivery or before first use, say so.
- Marking and tagging: any ID, colour tag or register format your site uses — see the lifting equipment register.

Common questions
- Why do suppliers ask for the shackle pattern?
- Because the same nominal size carries different ratings in different patterns and grades — for example 5.5 t, 8.5 t or 12.5 t at 1".
- What is effective length on a sling?
- The length from bearing point to bearing point — for example from the inside of the master link to the inside of the hook.
- Do rated items come with certificates?
- Yes, our rated items ship with the manufacturer’s test certificate.
- Can you arrange third-party inspection?
- Tell us your site’s requirement with the enquiry and we will confirm what we can arrange.
- Can I send a photo instead of specifications?
- For a replacement, yes — a photo of the item and its markings answers most questions.
