This Technical Specification should be used together with the other relevant parts of the standard series. As
such, they specify general conditions, requirements and methods to prevent hazards in hooks as part of all
types of cranes.
This Technical Specification covers the following parts of hooks and types of hooks:
? bodies of any type of point hooks made of steel forgings;
? machined shanks of hooks with a thread/nut suspension.
This Technical Specification is applicable to hooks from materials with ultimate strength of no more than
800 N/mm and yield stress of no more than 600 N/mm.
The following is a list of significant hazardous situations and hazardous events that could result in risks to
persons during normal use and foreseeable misuse. Clauses 4 to 8 of this document are necessary to reduce
or eliminate the risks associated with the following hazards:
a) Exceeding the limits of strength (yield, ultimate, fatigue);
b) Exceeding temperature limits of material;
c) Unintentional disengagement of the load from the hook.
The requirements of this Technical Specification are stated in the main body of the document and are
applicable to hook designs in general. The hook body and shank designs listed in Annexes A, B and G are
only examples and should not be referred to as requirements of this Technical Specification.
This Technical Specification is applicable to cranes, which are manufactured after the date of approval of this
standard by CEN, and serves as a reference base for product standards of particular crane types.
