It s
19、pecifies requirements and test conditions which have to be observed for safety reasons. Swing derricks are used for transfer of crew members ashore and back to the vessel for laying out ropes during mooring and unmooring operations, particularly when the vessel is close to canals or riverbanks and w
20、hen no other safe means of getting ashore in those cases is possible. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

Swing derrick 5 Construction NOTE. T
29、he construction as described in annex A is an example of a swing derrick made of steel. 5.1 Jib The jib shall consist of seamless tube. The tube ends shall be sealed. If tubes of different diameters are used for the jib, these shall be inserted into one another and fully welded. All welded seams sha
30、ll be designed to be airtight. If steel tubes are used the inside of the tube shall be treated with an appropriate protective coating. The jib shall be secured aboard ship in such a way that unintentional movement is avoided and that it does not unduly obstruct the working areas and walkways. The mi
31、nimum diameter of the jib measured between handles shall be 75 mm. 5.2 Pillar The pillar may be either a structure especially erected to support the jib and jib guy or any other appropriate component part of the vessel (e.g. hatch coaming). The component part shall be firmly connected to the hull an
32、d shall not unduly obstruct the working areas and the walkways. 5.3 Swivel The swivel shall be designed to ensure easy slewing of the jib. Bending moments resulting from the jib load shall not be transmissible to the swivel. The bearing bolt shall be locked. 5.4 Jib guy Round steel bars or steel wir
33、e ropes may be used for the jib guy. If steel wire ropes are used, their ends shall be fitted with means of thimbles. The rope ends shall be provided with clamps. Splices and screw rope clamps shall not be used. 5.5 Jib guy support The jib guy support and the swivel shall lie along one axis. As far
34、as possible, the jib guy support shall be positioned vertically above the swivel when the ship is on even keel or it shall be moved in the direction of the bow by a length dimension which is related to half the difference in trim between the light and loaded conditions. The jib guy support shall ens
35、ure easy slewing when loaded. The bearing bolt shall be locked. 5.6 Turnbuckle By means of an easily accessible turnbuckle the outer end of the jib shall be adjustable in height in such a way that the upper range between the handles can be adjusted above the walkway by a dimension of 800 to 900 mm.
36、The turnbuckle shall be secured to prevent unintentional movement. One end of the turnbuckle may be integral with the jib guy support.Page 5 EN 1255 : 1995 BSI 1996 5.7 Shackle The jib guy and turnbuckle shall be connected by means of a shackle. Shackle pins shall be locked to prevent unintentional
37、movement. 5.8 Handle The handles shall be made of the same material as the jib and shall be welded to it. 5.9 Hauling line The hauling line shall have a minimum diameter of 10 mm and shall be fitted on the upper side of the jib, approximately mid-length. The free end shall also be attached on the up
38、per side in such a way that it may be easily untied and fastened. The secured inner end of the hauling line shall be within 0,5 m of the base of the swivel. 5.10 Surface protection All parts of the swing derrick shall be permanently protected against the influence of weather. Steel wire ropes shall
39、be hot dip galvanized in accordance with ISO 2408. 6 Testing 6.1 In general Testing of the swing derrick is carried out by visual examination and measurement effected by authorized institutions after installation on board. NOTE. Authorized institutions are registered at CEN and examined in conformit
40、y with European Regulations. 6.2 Strength test First the jib shall be slewed in such a way that the area between the handles is vertically above the ships side. Then the jib shall be loaded with a single load of 200 kg centrally between the handles. The deflection measured in the loaded area shall n
41、ot exceed 3 % of the jib length. There shall be no permanent deformation after the load has been removed. Then the jib shall be loaded again with the single load of 200 kg centrally between the handles and slewed over the full slewing range. After the load has been removed there shall be no permanen
42、t deformation. 7 Designation Designation of a swing derrick as shown in figure A.1 with a jib length of l = 8500 mm: Swing derrick EN 1255 8500 8 Marking The swing derrick shall be marked by means of a manufacturers name plate. This name plate shall be weatherproof and be permanently fitted on the j
43、ib near the swivel. It shall contain the following information: Swing derrick EN 1255 jib length in millimetres Permissible load capacity 100 kg Manufacturer or supplier (Name, place, country) Test markPage 6 EN 1255 : 1995 BSI 1996 50 50 1750 1750 l l d 1 d 2 2 900 Figure A.1 Swing derrick with bui
