English Rope Tricks - lesson 4
As canal traffic increased the problem of rope wear on bridges and locks was tacked with more ingenuity.
This cast iron rubbing strip on the Shropshire Union canal may have protected the brickwork but took some wear itself
At Bank Newton on the Leeds & Liverpool canal a timber roller was employed
At Stone on the Trent & Mersey the wooden roller was clad in wrought iron
This technique was also employed on this lock at Kidsgrove on the Trent & Mersey
