EN 15056:2006+A1:2009 (E) 5 Introduction This standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

EN 15056:2006+A1:2009 (E) 6 1 Scope This European Standard specifies safety requirements for spreaders used with cranes designed for the purpose of handling ISO containers based on ISO 668 including other lengths such as 45 ft. The connection between the spreader and the container is by the use of twistlocks that engage into the container’s upper corner castings. The standard deals with all significant hazards, hazardous situations and events relevant to container handling spreaders, when used as intended and under conditions foreseen by the manufacturer (see Clause 4). The spreader is interfaced to the crane’s control and safety system. This European Standard does not cover the following types of spreaders: — hand operated spreaders (without external power supply); — bottom lift grapple spreaders used for swapbodies and road trailers. This European Standard does not deal with the lifting of persons. This European Standard is applicable to spreaders which are manufactured after the date of approval by CEN of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
