EN 13155:2003+A2:2009 (E) 4 Introduction This European Standard has been prepared to be a harmonized standard to provide one means for non-fixed load lifting attachments used on cranes to conform with the essential health and safety requirements of the Machinery Directive, as amended.
This European Standard is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards 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 non-fixed load lifting attachments which have been designed and built according to the provisions of this type C standard. 1 Scope This European Standard specifies safety requirements for the following non-fixed load lifting attachments for cranes, hoists and manually controlled load manipulating devices:
 plate clamps;  vacuum lifters;  self priming,  non-self priming (pump, venturi, turbine);  electric lifting magnets (battery fed and mains-fed);  permanent lifting magnets;  electro-permanent lifting magnets;  lifting beams;  C-hooks;  lifting forks;  clamps; defined in clause 3.
This standard does not specify the additional requirements for:
 non fixed load lifting attachments in direct contact with foodstuffs or pharmaceuticals requiring a high level of cleanliness for hygiene reasons;  hazards resulting from handling specific hazardous materials (e.g. explosives, hot molten masses, radiating materials); SIST EN 13155:2004+A2:2009



EN 13155:2003+A2:2009 (E) 5  hazards caused by operation in an explosive atmosphere;  hazards caused by noise;  electrical hazards;  hazards due to hydraulic and pneumatic components.
This standard does not cover the hazards related to mechanical strength of structural elements of attachments designed for more than 20 000 lifting cycles.
NOTE The coefficient of utilization specified in clause 5.1.1 ensures that no fatigue verification is needed for less than 20 000 cycles. This is in accordance with the well accepted calculation codes e.g. FEM 1001. This standard does not cover attachments intended to lift above people. This standard does not cover slings, ladles, expanding mandrels, buckets, grabs, or grab buckets. The hazards covered by this European Standard are identified in clause 4. This European Standard does not cover hazards related to the lifting of persons. This European Standard is applicable to non-fixed load lifting attachments which are manufactured after the date of approval by CEN of this standard.

EN 13155:2003+A2:2009 (E) 19 5 Safety requirements and/or measures 5.1 General requirements The attachment shall comply with the safety requirements and/or measures of this clause. In addition, the attachment shall be designed according to the principles of #EN ISO 12100$ for hazards relevant but not significant which are not dealt with by this standard.
5.1.1 Mechanical load bearing parts 5.1.1.1 The mechanical load bearing parts shall have a mechanical strength to fulfil the following requirements:
1) the attachment
shall be designed to withstand a static load of three times the working load limit without releasing the load even if permanent deformation occurs; 2) the attachment shall be designed to withstand a static load of two times the working load limit without permanent deformation.
5.1.1.2 Attachments intended to tilt shall be designed for an angle exceeding minimum 6° the maximum working angle. Attachments not intended to tilt shall be designed for an angle of minimum 6°.
5.1.2 Controls The controls of the attachment shall be in accordance with the following clauses of prEN 13557:2003 where applicable:
5.1.1, 5.1.10, 5.2.3.1.1, 5.2.3.1.2, 5.2.3.1.3, 5.2.3.2.1, 5.2.3.2.2, 5.2.3.2.3, 5.2.3.2.4, 5.2.3.2.5, 5.2.3.2.6
5.1.3 Handles An attachment that is intended to be guided manually shall be equipped with handle(s), arranged so that finger injuries are avoided. Handles are not required if features have been built in to provide natural handholds.
5.1.4 Requirements for slings which are integrated Slings which are an integrated part of the attachment shall be in accordance with the appropriate following standards:  EN 818-4;  EN 818-5;  prEN 13414-1;  EN 1492-1;  EN 1492-2.

EN 13155:2003+A2:2009 (E) 20 5.1.5 Stability during storage When not required for use it shall be possible to set down the attachment so that it is stable during storage. To be regarded as stable it shall not tip over when tilted to an angle of 10° in any direction. This shall be achieved either by the shape of the attachment or by means of additional equipment such as a stand. 5.2 Specific requirements for each category of attachment 5.2.1 Plate clamps
5.2.1.1 Under the conditions specified by the manufacturer, it shall not be possible to unintentionally release the load, in particular by the following influences:
