In respect of ski-tows, the drafting of this European Standard has been guided by the works of the International Organisation for Transportation by Rope (OITAF). According to the CEN/CENELEC Internal Regulations, the national standards organizations
27、 of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,
28、Spain, Sweden, Switzerland and United Kingdom EN 12927-4:2004 (E) 5 1 Scope This part of EN 12927 specifies the safety requirements applicable to end fixings of steel wire ropes for installations for passenger transportation by rope. This standard is applicable to the various types of installations
29、and takes into account their environment. This part of EN 12927 applies to the following types of end fixing when used in installations for passenger transportation by ropes in conformity with EN 12927-1. filled socket; clamp socket; drum; bolted clamp; wedge socket; spliced eye; gripped eye; ferrul
30、e secured eye; lever winch. Taking its scope into account, it does not include requirements relating to the prevention of accidents and the protection for workers. It does not apply to installations for the transportation of goods, nor to inclined lifts. 2 Normative references The following referenc
