ISO 17440 is intended to be used together with the other relevant International Standards in its series. As such, they specify general conditions, requirements and methods to prevent hazards in hooks as part of all types of cranes. This International Standard covers the following parts of hooks and types of hooks: - bodies of any type of point hooks made of steel forgings; - machined shanks of hooks with a thread/nut suspension. This International Standard is applicable to hooks from materials with ultimate strength of not more than 800 N/mm2 and yield stress of not more than 600 N/mm2. 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; c) unintentional disengagement of the load from the hook. The requirements of this International Standard are stated in the main body of the document and are applicable to hook designs in general. The hook body and shank designs listed in Annexes A, B and G are only examples and should not be referred to as requirements of this International Standard. This International Standard is applicable to cranes manufactured after the date of its publication, and serves as a reference base for product standards of particular crane types.
