1 Scope
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:
NOTE 1 Principles of this Technical Specification can be applied to other types of shank
hooks and also where stress concentration factors relevant to that shank construction
are determined and used. Plate hooks, which are those, assembled of one or several
parallel parts of rolled steel plates are not covered in this Technical Specification.
This Technical Specification is applicable to hooks from materials with ultimate strength
of no more than 800 N/mm2 and yield stress of no more than 600 N/mm2.
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.
NOTE 2 This CEN/TS 13001‑3‑5 deals only with the limit state method in accordance with EN 13001‑1.
