Automatic trailer coupling, also with distance control and remote indicator for heavy duty centre axle trailers using 50 mm drawbar eyes ec type approval according to class c 50-x in compliance with ec regulation 94/20 (12 pages)
Automatic trailer coupling for connection with hinged drawbar trailers with drawbar eyes 40 acc. to din 74054 or 40mm acc. to iso 8755 and equal drawbar eyes of class s in accordance with the directive 94/20 ec or ece 55-01 (9 pages)
The coupling must only be operated in normal industrial atmospheres. Since aggressive media may attack the coupling components, screws and elastic buffer rings, they repre- sent a risk for the operational safety of the coupling. Consult RINGFEDER POWER TRANSMISSION in such cases.
The coupling parts can be stored in their delivered standard-state for 6 months in a dry, roofed place at normal room temperature. For a longer storage duration a long-term preser- vation is necessary (consult RINGFEDER POWER TRANSMISSION). The elastic intermediate ring must not be subjected to ozone containing mediums, direct solar influence or strong light sources with ultraviolet-light.
