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;
 ĞůĞǀĂƚŽƌƐ;ŵĂŶƵĂůůLJŽƌƌĞŵŽƚĞůLJŽƉĞƌĂƚĞĚͿ;
defined in clause 3.

EKd͗ůĞǀĂƚŽƌƐŝŶƚŚŝƐĐŽŶƚĞdžƚĂƌĞĐŽůůĂƌƐŚĂƉĞĚĐůĂŵƉƐƵƐĞĚŝŶƚŚĞŽĨĨƐŚŽƌĞĚƌŝůůŝŶŐŝŶĚƵƐƚƌLJƚŽŚĂŶĚůĞĚƌŝůů
ƉŝƉĞƐĂŶĚŽƚŚĞƌƚƵďƵůĂƌĐŽŵƉŽŶĞŶƚƐ͘

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);
 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.
