Product Overview

The EN 818-7 lifting chain is manufactured strictly in accordance with the European EN 818-7 standard, pairing precision-welded link construction with high-strength steel to give the unit a dependable load path for lifting service. 

Available with hot-dip zinc, dacromet, metal-coated, black, oiled, and various other surface treatments, it's built for lifting and hoisting applications where reliable strength and corrosion resistance are essential.


Safety is engineered in: the chain is designed with a 4-fold safety factor and a proof load of 2.5 times the working load limit, giving you consistent, verifiable performance under rated loads. It shares its production line and surface treatment 

options with our [related model, e.g., DIN 766 chain], but follows the EN 818-7 specification — see the comparison below to confirm which fits your application.

Why Choose a Trolley-Mounted Electric Chain Hoist?

Not every lifting job needs a special alloy or an oversized chain. Where a chain is called on to lift, secure, and rig loads at a rated capacity — day in, day out — a dependable EN 818-7 lifting chain does the job with strength you can verify. The EN 818-7 is built for exactly that: dependable, rated lifting with a 4-fold safety factor and a proof load of 2.5 times the working load limit.



Which EN 818-7 chain fits your job? IIf your work runs outdoors or in harsh, corrosive environments, the hot-dip zinc or dacromet finish delivers long-term protection. If you need a clean, economical surface for indoor general service, the black, oiled, or metal-coated finish is the practical choice. If your loads are heavy, step up to larger sizes up to 22 × 66 mm with a working load limit of 15.3 t — see the spec table below to match the right chain to your application.

How to Select the Right EN 818-7 Lifting Chain

01

Confirm your lifting application

The EN 818-7 is a rated lifting chain — choose it for load lifting, rigging, and sling assemblies where working load limits and verified strength are mandatory.

02

Match chain size to load

Select from 3×9 mm to 22×66 mm based on your heaviest rated load, plus safety margin — working load limits range from 0.28 t to 15.3 t, with breaking loads from 11.3 kN to 610 kN.

03

Choose the right surface treatment

Working outdoors or in corrosive conditions? Go with hot-dip zinc or dacromet for long-term protection. Indoor general service? Black, oiled, or metal-coated finishes are the practical choices.

04

Verify dimensions and documentation

Confirm the inside and outside width of the chain matches your application, and request the test certificates showing the proof load and breaking load before ordering.
