Dear EG RL Committee member, 

In your capacity as a member of one of the EG-RL committees, you are hereby requested to comment on the international standard referred to in this e-mail. 

 

This document is due 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 gear components of cranes. This document covers the following types of gears and adjoining components, used in mechanisms for any principal movement of a crane: - cylindrical helical and spur gears and bevel gears, with involute profile geometry; - gears arranged in enclosed housings or as open gears; - gears made from steel or iron and gear boxes made from steel, iron or aluminium; - gears and pinions with lubrication; - gear boxes and single gear arrangements with bearings and shafts supporting the gears. 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 7 of this document are necessary to reduce or eliminate the risks associated with the following hazards: - exceeding the limits of strength (yield, ultimate, fatigue); - exceeding temperature limits of material. This document is applicable to cranes, which are manufactured after the date of approval of this document by CEN, and serves as a reference base for product standards of particular crane types.

Best regards,
