US group Ramsey Chain was recently granted a European patent for its Lifeguard wear protected conveying chains (EP 2368816 B1).
Already covered by three United States patents, Lifeguard chains utilise interlocking side links that guard against pin head wear and greatly reduce the size of gaps between adjacent side plates.
With much smaller gaps between the side plates, smooth product transfer on and off the conveying surface is assured and the potential for snagging on lateral guides is reduced.
These features are particularly beneficial when conveying small bottles. Lifeguard is only available from Ramsey and is currently available in 1/2" pitch, as well as 1" pitch extended pitch.
