[Also in Group XXV] Supply cables 4 which feed a moving consumer appliance are carried by the cross-pieces 2 mounted between the two strands of chain 1. Each strand comprises twin inner links 11 and twin outer links 10 connected together at 12. Each pair of links 10 carries a disc 22 therebetween, which disc co-operates with the adjacent edges of links 11 to define the curvature to which the chain can be bent. Also, each pair of links 10 or 11 is connected to its neighbour by a pair of blocking links 13, which prevent the entry of foreign bodies and the crushing of fingers. |
