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.
