Cranes - Safety - Tower cranes

This European Standard specifies safety requirements:
-   for tower cranes and
-   for climbing systems used with the tower cranes/masts of tower cranes for which they have been designed. They are classified as external or internal systems.
This European Standard applies to tower cranes for construction work, which are either erected by parts or self erecting cranes.
This European Standard is not applicable to mobile cranes, mobile harbour cranes, crawler cranes, slewing jib cranes, bridge and gantry cranes, offshore cranes, floating cranes, loader cranes, hand operated cranes or railway cranes.
This European Standard deals with all significant hazards, hazardous situations and events relevant to tower cranes, when used as intended and under conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards (see Clause 4).
The significant hazards covered by this European Standard are identified in Clause 4.
This European Standard does not cover hazards related to:
-   the lifting of persons by the tower crane itself.
The requirements related to Electromagnetic compatibility (EMC), the specific hazards due to external influence on electrical equipment, potentially explosive atmospheres and ionising radiation are not covered by this European Standard.
This European Standard covers hazards related to the lifting of persons using a climbing system.
This European Standard is not applicable to tower cranes !and climbing systems" which are manufactured before the date of publication by CEN of this European Standard.

5.4.4.2 Crushing hazard between moving parts Where persons could be present between moving parts a safety distance of at least 0,5 m shall be observed. Where such a distance cannot be obtained, guards (when possible) and warning notices shall be fitted. SIST EN 14439:2007+A2:2009

EN 13586 are not applicable. The dimension m (clear width, Table 4) may be reduced to 0,2 m and the dimension d (distance between the centre line of the rung and vertical surface) may be reduced to 0,1 m allowing the use of the rung at least by one foot. 5.4.4.4 Hatch apertures If the crane construction does not allow larger dimensions, for type 2 access according EN 13586 the minimum dimensions for effective hatch apertures shall be 0,5 m by 0,4 m. 5.4.4.5 Access provided in a horizontal jib 5.4.4.5.1 General If it is not possible to lower the jib to the ground to carry out a visual inspection of the jib, a basket fixed to the trolley shall be provided. In addition a walkway with:  side protection, or  personal protective device against the falls shall be fixed along the jib to reach the mechanism(s). When during erection/dismantling, repair or the maintenance the basket cannot be used, the use of personal protective device against the falls shall be possible all along the jib. 5.4.4.5.2 Walkway The width of the walkway shall comply with EN 13586:2004, Table 6 type 2. When the size of the jib is sufficient to walk inside the jib (dimension between the walkway and the upper member equal or more than 1,8 m), toe boards shall be provided on each side of the walkway with a minimum height of 0,03 m. When the dimension between the walkway and the upper member is less than 1,8 m, toe board is provided only on one side (see Figure 1). SIST EN 14439:2007+A2:2009

Figure 1 5.4.4.5.3 Position of the walkway, handrail and steel wire rope Manufacturers shall take into consideration the dimension of the jib when determining the position of the walkway, hand rail and steel wire rope. 5.4.4.5.4 Basket The minimum dimension of the length/width of the basket shall be 0,5 × 0,35 m. Manufacturers shall take into consideration the weight and the number of persons when determining the basket. The side protection shall comply with EN 13586:2004, Table 7, type 2, walkway. Instructions and markings shall be provided for the use of the basket:  how to reach the basket;  admissible load and number of persons;  warnings concerning residual risks e.g. shearing, entanglement. 5.4.5 Lighting A fixed non-dazzling service lighting shall be provided and so arranged that the necessary illumination of the control is provided. The minimum illumination shall be 50 lux. When the general area lighting does not permit sufficient illumination in a machinery cabinet, supplementary lighting shall be provided. For maintenance, the minimum illumination shall be 200 lux which may be obtained by additional movable lighting. SIST EN 14439:2007+A2:2009

EN 12077-2 (5.5.1.2):  it shall be indicated by a continuous green light located so that it is visible to the persons next to the crane;  a yellow light installed on the crane visible to the driver shall give a warning of approach to the rated capacity at a value which gives the crane driver time to react to the warning and prevent the crane from being overloaded. This indicator is not necessary if this information is available on the remote control. 5.5 Noise reduction 5.5.1 Noise reduction at source at the design stage Tower cranes shall be so designed and constructed that risks resulting from the emission of airborne noise are reduced to the lowest level taking account of technical progress and the availability of means of reducing noise, in particular, at source. Recommended practice for the design of the low-noise machinery is given in EN ISO 11688-1. NOTE EN ISO 11688-2 gives useful information on noise generation mechanism in machinery. For tower cranes, the main source of noise is the lifting mechanism. 5.5.2 Information about the residual noise emitted Information on the residual noise shall be given by the manufacturer of the tower crane, see also 7.2.5. 6 Verification of the safety requirements and/or protective measures 6.1 General Only verifications of additional requirements of the Clause 5 are given in the Table 7, the others are already covered by the particular standard. !Additional methods of verification and requirements for fitness for purpose applicable to climbing systems are given in Annex F." 6.2 Method of verification It is necessary to verify that the requirements of this European Standard have been incorporated in the design and manufacture of a tower crane. Either one or a combination of the following shall achieve this: a) measurement; b) calculation; c) visual examination; d) functional tests; as described in Table 7 and Annex D, clause D.1.
