Standards Development

Scope

This document 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 mechanical hazards of cranes by design and theoretical verification.

Specific requirements for particular types of cranes are given in the appropriate European standard for the particular crane type.

This document covers shafts (axles) in cranes that are not dealt with by other EN 13001 standards (e.g. pinned connections in EN 13001-3-1). It is not intended for axles being part of standard components, e.g. gearboxes, motors …, however, those axles shall be designed using load actions from EN 13001-2 and classification parameters of EN 13001-1.

NOTE EN 13001-3-7 is under preparation for gears and gearboxes and deals with load actions for axles in gear boxes.

The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 4 to 7 of this document are necessary to reduce or eliminate risks associated with the following hazards:

— exceeding the limits of strength (yield, ultimate, fatigue);

— exceeding temperature limits of material or components.

This document is not applicable to cranes which are manufactured before the date of its publication as EN and serves as reference base for the European standards for particular crane types (see Annex C).

NOTE prEN 13001-3-8 deals only with limit state method in accordance with EN 13001-1.

Purpose

The standard will be an essential part of the EN 13001 series of standards that are needed for the theoretical strength verification of cranes.

History: WI 00147157 - prEN 13001-3-8 draft was submitted to the CEN Enquiry between 2018- 05-24 and 2018-08-16. It was agreed in WG 2 to launch a second CEN Enquiry. However, the work item was interrupted 2019-12-20(2nd Delivery was available) due to timeout. Therefore, the "second CEN" survey in WI 00147157 will be carried out in this New Work Item as CEN ENQ (stage 40).
