Spanometer – Overhead Cable/Rope Measuring Device
This machine has been designed to measure lengths of overhead cables. The unit is hung on the cable and a vertically movable pulley is used to clamp the measuring wheel to the cable.
A shackle is provided to enable the machine to be pulled along. A mechanical counter then displays the length/distance that the machine has moved. Its primary use is for positioning of spacers on overhead power lines. Can accommodate cable sizes between 8 – 43mm diameters.
