Grade 8 Lifting Chain Slings - Single Leg
Hack8 single-leg (1-leg) chain slings are a pre-assembled and certified range of grade 8 or, as they are sometimes referred to, grade 80 lifting chain slings, which are available in chain diameters starting from 7mm and incrementally increasing up to the largest size of 32mm.
Alongside the Hack8 ready made chain sling lines, there is also the Hack10 range of grade 100 chain sling components (as with grade 80 being referred to as grade 8, so too you will see grade 10 and grade 100 - these are referring to the one and same, just as with grade 12 and grade 120) which primarily have a higher capacity-to-diameter ratio (and so also capacity-to-weight ratio) than the lower grade 80 chain and components.
The length of the chain sling can be supplied as any length that you require (give or take a chain link length), but a chain sling can also be supplied with a temporary shortening grab hook, which is often very useful when dealing with unsymmetrical or uneven loads, or simply an array of different-sized objects being lifted.
We refer to the length of the chain sling as its EWL, or Effective Working Length, which is measured from the bearing point of the main ring or master link to the bearing point of the hook or other end termination.
Key Features of Hack8 1-Leg Lifting Chains
- Component standards: Components are designed and manufactured in accordance with EN1677-1 and are suitable for use in chain slings certified to EN818-4.
- Chain standards: designed and manufactured in accordance with EN818-2 and suitable for use in chain slings certified to EN818-4.
- RFID Enabled: chain sling assembly tags contain an RFID chip to relay product and certification details digitally.
- Product sizes: available for chain sizes from 7mm to 32mm and with working load limits from 1.5 tonnes to 31.5 tonnes.
- Temperature: operational temperature range of - 40°C to + 200°C without reduction in working load limit.
- Material: alloy steel.
- Testing: components and chain proof load tested to 2.5 times the working load limit.
- Safety factor: 4 : 1.

Chain Sling Selection Guidance
This information provides detailed WLLs for various chain sizes and configurations, emphasising the importance of selecting the correct chain size and configuration for safe lifting operations. All lifting applications should be assessed by a competent person in order to establish the size and type of sling required.
Lifting Reach - Effective Working Length
Also known as bearing to bearing (b-b) or chain length.
The reach of a chain sling is the distance between the bearing points of the upper and lower terminal fittings. This distance, commonly known as the “Bearing to Bearing”, should be quoted when ordering slings.
Shortening grab hooks may be fitted to a sling, making the reach adjustable, hence increasing the versatility of the sling.
