EN 13001-3-5:2016/FprA1
(Amendment)Cranes - General design - Part 3-5: Limit states and proof of competence of forged and cast hooks
Cranes - General design - Part 3-5: Limit states and proof of competence of forged and cast hooks
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.
This European Standard covers the following parts of hooks and types of hooks:
- bodies of any type of hooks made of steel forgings;
- machined shanks of hooks with a thread/nut suspension.
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.
NOTE 1 Cast hooks and plate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered in this European Standard.
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.
The requirements of this European Standard are stated in the main body of the document and are applicable to forged hook designs in general.
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.
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.
NOTE 2 This part of EN 13001 deals only with the limit state method in accordance with EN 13001-1.
FprA1:
Add after 1st paragraph the following sentence:
"
It has to be used together with the other generic parts of EN 13001 series of standards, see Annex L.
".
Replace in 2nd paragraph the 1st list item with:
"
- bodies of any type of hooks made of steel forgings or steel castings, including stainless steel;".
Replace NOTE 1 with:
"
NOTE 1 Plate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered in this document.".
In the 4th paragraph, replace the 1st list item with:
"
a) exceeding the limits of yield strength, ultimate strength, fatigue strength, brittle fracture;".
Replace the 5th paragraph with:
"The requirements of this document are stated in the main body of the document and are applicable to hook designs in general.".
After 4th paragraph, add the sentence:
"
The hazards covered by this document are identified by Annex M.

Diese Europäische Norm gilt für folgende Hakenteile und Hakenarten:
- alle Arten von geschmiedeten Spitzhakenkörpern
- bearbeitete Hakenschäfte mit Gewinde-/Mutter-Aufhängung.
ANMERKUNG 1 Die Grundsätze der Europäische Norm sind auch auf andere Arten von Gabelhaken sowie bei der Ermittlung und Verwendung von Spannungskonzentrationsfaktoren, die für die betreffende Schaftkonstruktion von Bedeutung sind, anwendbar. Lamellenhaken, die aus einem oder mehreren parallel angeordneten Blechen aus Walzstahl zusammengesetzt sind, sind nicht Gegenstand dieser Europäische Norm.
Die vorliegende Europäische Norm gilt für Haken aus Werkstoffen mit einer Bruchfestigkeit von maximal 800 N/mm2 und einer Fließgrenze von maximal 600 N/mm2.
Im Folgenden sind signifikante Gefahrensituationen und Gefahrenereignisse aufgeführt, die zu Gefahren für den Menschen während des normalen Gebrauchs und bei vorhersehbarem Missbrauch führen könnten. Abschnitte 4 bis 8 dieses Dokuments sind wichtig, um Risiken, die mit nachfolgend genannten Gefahren verbunden sind, zu minimieren oder zu verhindern:
a) Überschreiten der Festigkeitsgrenzwerte (Fließen, Bruch, Ermüdung);
b) Überschreiten der Temperaturgrenzwerte des Werkstoffs;
c) unbeabsichtigtes Aushängen der Last vom Haken.
Die Anforderungen dieser Europäische Norm sind im Hauptteil des Dokuments beschrieben und gelten für Hakenkonstruktionen allgemein. Die in den Anhängen A, B und G aufgeführten Bemes¬sungen von Hakenkörpern und Hakenschäften dienen nur als Beispiel und sind nicht als Anforderungen dieser Europäische Norm zu verstehen.
Diese Europäische Norm gilt für Krane, die nach dem Datum der Genehmigung dieses Dokuments durch CEN gefertigt werden, und dient als Referenzgrundlage für Europäische Norm von speziellen Krantypen.

applied (see 4.1.2) and independent whether classification of the material is applied or not (see 4.1.3).
The hook material in the finished product shall have sufficient ductility to permanently deform before
losing the ability to carry the load, at the temperatures specified for the use of the hook. Particularly the
hook material shall fulfill the following conditions:
— the ratio of ultimate strength (f ) to yield stress (f ) f /f ≥ 1,2. For the materials, which do not
u y u y
fulfill this condition, the design value of f shall be limited to f /1,2;
y u
— the percentage elongation at fracture A ≥ 10 % on a gauge length LS5,65× (where S is the
0 0
original cross-sectional area).
The hook material, after heat treatment, shall have minimum Charpy-V impact toughness in accordance
with Table 2.

To satisfy the requirements of the operating temperature, the manufacturer shall select the steel, which
after suitable heat treatment, shall be consistent with achieving the chosen mechanical property grade
for the selected hook form, taking into account its individual ruling thickness.
The steel shall be fully killed, stabilized against strain age embrittlement, ensured by having sufficient
content of aluminium (minimum of 0,02 %). The steel shall contain no more sulphur and phosphorus

The steel for forged hooks shall have a grain size of 8 or finer, with grain size determined in accordance
with EN ISO 643.
Where quenched and tempered steel is used, the hardenability of the steel shall fulfil the requirement of
the Jominy-ratio given in Table 4. The Jominy-ratio J30/J1,5 is the ratio between J30 and J1,5, where J30
and J1,5 mean the hardness at depths 30 mm and 1,5 mm correspondingly, determined by Jominy face-
quenching test in accordance with EN ISO 642. The tests shall be carried out per melt and the values be
given in the technical hook information, see Annex J. For more information on hardening properties and
hardness profiles, see EN 10083-3.
Where the mechanical properties of cast hooks are tested for each single hook, the hardenability may be
verified by HB-testing in accordance with EN 6506-1 in the section of the test specimen at 1,5 mm and
30 mm depth from the surface. The hardness ratio shall fulfil the minimum requirement (Jominy-ratio)

The manufacturing process, in factory tests and delivery conditions shall meet the requirements of
EN 1559.
The castings shall be heat-treated to meet the mechanical properties of the applicable grade.
Prior to quenching, the ingate system is to be roughly removed. After quenching excess material from

The surface roughness of the hook seat in the finished product shall be equal to or better than
Rz 500 µm, for example S2 in accordance with EN 1370. Grinding may be used to reach the required
surface quality. Any grinding marks shall be in a circumferential direction in respect to the seat circle.
After heat treatment the surface of a cast hook shall be inspected for defects using appropriate NDT-
methods. Requirements of quality class 2 of EN 1369 or class 2 of EN 1371-1 shall be met.
The inner quality has to be inspected by ultrasonic inspection in accordance with EN 12680-1 and
quality class 2 shall be met.
Weld procedures for production welding are required for all repairs during manufacturing, and shall be
qualified in accordance with ISO/TR 15608:2013-04 and EN ISO 15614-1. Subsequently the welded
part must be post weld heat
