A chain track junction link of the type having some characteristics of a conventional link is constructed as two complementary portions in order to effect opening and closing of a chain track. A union of the two portions of the link is effected by a connection member having ends of approximately prismatical shape, the member being I-shaped in section. In the two portions of the link are a plurality of grooves shaped in such a way that, when the two portions of the link are jointed, they form an approximately prismatic hole suitable for receiving the member which holds the two portions of the link firmly together. In order to increase the stability of the joint, a track shoe is screwed, using holes, to the head of the member. |
