1. Legal basis
The following German and European standards and regulations apply when using hoisting chains:
- EU Directive 98/37/EC Equipment and Product Safety Act (GPSG)
- BGR 500-2.8
- EN 818
- EN 1677
2. Marking
Only hoisting chains that meet the relevant DIN/EN standard and are marked accordingly may be used in hoisting applications.
Hoisting chains - example standards and quality classes:
Example of a correctly-marked EN 818 single-strand hoisting chain in quality class 8.
Maximum chain lifting capacity
Nominal diameter of chain used
Designation for the number of chain strands (here: single-strand)
Chain symbols
Unique identification number, corresponds to certificate of compliance
Manufacturer time or mark
CE marking
3. Hoisting chain versions
Hoisting chains are available as 1-strand to 4-strand chain hangers as well as an endless chain sling.
4. Proper use
High-strength hoisting chains (quality class 8; please refer to manufacturer's specifications for quality classes 10 and 12) can be used at temperatures of -40°C to +200°C. Hoisting chains may be used at temperatures of up to +400°C provided allowances are made for the reduction in lifting capacity.
Note: Always observe the permitted ambient temperatures when using a combination of different lifting tackle.
The hoisting chain is the only piece of lifting tackle that can be used around a sharp edge without any edge protection provided that a 20% reduction in lifting capacity is observed, or the next size up of nominal chain thickness is used. Edge protection must be used in all other circumstances. A sharp edge constitutes an edge whose radius "r" is smaller than the nominal thickness "d" of the hoisting chain. Refer to the lifting capacity charts or identification tag for the lifting capacity of hoisting chains.
Important: It must not be hoisted at angles of inclination exceeding 60°. The forces that are exerted above this angle of inclination are not permitted.

5. Safety note
The chain must be checked for any obvious defects before use.
Twisted chains must be straightened out before use.
Note: Use a swivel adapter to avoid twisted chains.
The crane hook tip must not be used as the suspension point.
Damaged hoisting chains must never be used (BGR 500)
Mixing chain components of different quality classes is not permitted.
6. Check
The prescribed hoisting chain checks are governed by BGR 500. Maintenance work my only be carried out by trained and qualified personnel in accordance with BGR 500 2.8.
