This European Standard is to be used together with EN 13001-1 and EN 13001-2 and, as such, they specify general conditions, requirements and methods to prevent by design and theoretical verification, mechanical hazards in crane hooks.<\/p>\n
It is intended to be used together with the other generic parts of EN 13001 series of standards, see Annex L.<\/p>\n
This European Standard covers the following parts of hooks and types of hooks:<\/p>\n
bodies of any type of hooks made of steel forgings or steel castings, including stainless steel;<\/p>\n<\/li>\n
machined shanks of hooks with a thread\/nut suspension.<\/p>\n<\/li>\n<\/ul>\n
Principles of this European Standard can be applied to machined shanks of hooks in general. However, stress concentration factors relevant to designs not given in this standard would have to be determined and applied.<\/p>\n
The hazards covered by this document are identified by Annex M.<\/p>\n
\nNOTE 1 Plate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered in this document.<\/p>\n<\/blockquote>\n
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:<\/p>\n
\n
- \n
exceeding the limits of yield strength, ultimate strength, fatigue strength, brittle fracture;<\/p>\n<\/li>\n
- \n
exceeding temperature limits of material.<\/p>\n<\/li>\n<\/ol>\n
The requirements of this document are stated in the main body of the document and are applicable to hook designs in general.<\/p>\n
The commonly used hook body and shank designs listed in Annexes A, B and F are only examples and should not be referred to as requirements of this European Standard. Annex I gives guidance for the selection of a hook size, where a hook body is in accordance with Annex A or B. The selection of hook form is not limited to those shown in Annexes A and B.<\/p>\n
This European Standard is applicable to cranes, which are manufactured after the date of approval of this European Standard by CEN, and serves as a reference base for product standards of particular crane types.<\/p>\n
\nNOTE 2 This part of EN 13001 deals only with the limit state method in accordance with EN 13001\u20131<\/p>\n<\/blockquote>\n
