Excavation chain for excavating track bed material

摘要

The chain has two movable connection points (2, 3) interconnected by adjacent chain links (1), where some of the chain links bear excavating elements (11) with scratch plates (12). Each chain link includes two releasably interconnected parts (5a, 5b), where the parts include the respective connection points for connection to the adjacent chain links. Each chain link is divided transversely to a connecting line of the chain link, where each chain link is divided in a dividing region (6), and the divided chain link is removable by a connecting pin.
