Abstract

The present invention relates to a ladle loop used as a connecting member between a pivot mounted on a ladle and the bail of a crane, wherein said loop comprises two parallel spaced-apart brackets. A bushing is provided in one end region for surrounding the pivot of the loop, while a pivot is provided in the other end region in the bail jaw of the crane hook. The bushing (4, 23), the pivot (11) and the brackets (2, 3, 21, 22) are made of materials having the same quality and are connected together so as to form a closed isotensile chain link while optimising the weight and shape.
