Abstract:

A link for a cutting chain comprises a reduced number of parts including a body section and a journal pin. A plurality of links can be joined to form the cutting chain. The cutting chain can be used on a trenching machine having a boom encircled by an endless chain. The link includes a top surface for the placement of cutting teeth. The link increases the freedom of cutting teeth placement, can extend the useful life of the cutting chain and the drive sprocket, can reduce thermal cracking and failure, and can resist lateral forces that would force the cutting chain from the boom.
