Of the many machines we see in the construction of the “modern era” canals, the cable way (it is also seen as one word, cableway) is likely the least noticed. However it is one of the few machines that has survived the through the years and is still in use today. The cable way was the true multi-tasker of the construction site.
A cable way is a very basic machine with two towers, a hoisting engine with a steam plant to power it, wire rope (cable), and a traveling carriage that ran along the cables.
Depending on what work needed to be completed, the contractor would build tall wooden towers so that the cable spanned the construction site. If the bases were mounted on flanged wheels on rails, the cableway could have movement in all three dimensions; side to side, back and forth, and up and down.
Cable ways were very good at spanning deep cuts such as along the Chicago Sanitary Canal or in Lockport on the NYS Barge Canal.
They were useful on sites with soft soils such as along the Hennepin Canal for dredging out muck and quicksand. They were useful on lock and dam sites that spanned deep or wide rivers and would “fly” in building materials and buckets of concrete. They were also very useful on sites where there might be blasting as the cable wouldn’t be damaged and could be left in place unlike a steam shovel or other large equipment. Depending on the diameter of the main cable, the cable way could lift and move tons of materials at one time.
Many manufacturers made cable way equipment as most of it consisted of the basic steam engine and hoisting machine that were used in many applications. In the Barge Canal photos you often see it described as the Lidgerwood cable way, but other manufacturers were Flory and Mundy.
