Introduction
This European Standard has been prepared to be a harmonized standard providing one means of
complying with the essential safety requirements of the Machinery Directive and associated EFTA
regulations.
The hooks covered by this Part of EN 1677 are normally supplied to be part of a sling, but they may
also be used for other applications. In such instances it is important that the hook design is checked to
ensure its fitness for the intended use.
The extent to which hazards are covered is indicated in the scope. In addition, lifting equipment shall
conform as appropriate to EN 292 for hazards that are not covered by this standard.
1 Scope
This European Standard specifies requirements for forged steel self-locking lifting hooks of Grade 8
having eye or clevis and pin up to 21,2 t working load limit (WLL), mainly for use in:
– chain slings according to EN 818-4
– steel wire rope slings according to prEN 13414-1
– textile slings according to EN 1492-1, EN 1492-2 .
intended for lifting objects, materials or goods.
The hazards covered by this part of EN 1677 are identified in clause 4.
Annex A gives the bases for calculation of hook dimensions.
Annex B gives an example of a designation systems for hooks of Grade 8.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1677-1 apply, together
with the following.
3.1
self-locking hook:
hook containing a locking mechanism, capable of being activated by the action of the load which, once
correctly closed and locked, can only be opened in the unloaded condition by de-activation of the locking
mechanism

4 Significant hazards
Accidental release of a load or release of a load due to failure of a hook puts at risk, either directly or
indirectly, the safety or health of those persons within the danger zone.
In order to provide the necessary strength and durability of hooks this Part of EN 1677 gives
requirements for the design, manufacture and testing to ensure the specified levels of performance are
met.
Since failure can be caused by the incorrect choice of grade and specification of hook, this Part of EN
1677 also gives requirements for marking and the manufacturer's certificate.
Errors of fitting can also lead to failure and this Part of EN 1677 contains dimensional requirements to
allow correct fit.
Risk of injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this
standard.
Those aspects of safe use associated with good practice are given in EN 818-6.
Table 1 contains those hazards which require action to reduce risk identified by risk assessment as being
specific and significant for forged steel self-locking hooks of grade 8.

5 Safety requirements
5.1 Design
The articulation and relative movement shall be in accordance with 5.1 of EN 1677-1:2000.
NOTE 1 The form of the hook is not specified in detail. For example, a minimum value of
dimension F (see Figure 1) as measured in any direction is specified so that the eye of the hook
can accommodate a pin, but the eye of the hook need not be circular.
The form of the upper end shall be either of the eye type or the clevis type as designated in Table 2.
A closed hook in the finished condition shall be able to withstand a bend test in accordance with 6.2.2
