Document Type and Number:
WIPO Patent Application WO2003064963
Kind Code:
A3
Abstract:
A chain wear measurement system (10) and/or method for determining an amount of wear in a section of chain (20) comprises a chain (20) or section of chain having a plurality of chain links connected together by a plurality of pins (12) or bolts (12') or the like. At least one end of at least one of the pins (12) or bolts (12') may have an extension (14) extending longitudinally therefrom. A sensor (28) is provided along a conveying path (24) of the chain (20) for sensing the presence of the pin (12) or bolt (12') and/or extension as the section of chain is conveyed along the conveying path (24). The sensor (28) provides a signal indicative of a detection of the pin (12) or pins or bolts (12'). A control (30) may be responsive to the sensor (28), such as to determine the degree of wear in the section of chain in response to one or more signals from the sensor (28).
