If you are using any kind of mechanical device, be very careful using that type of rope. It has a lot of stretch and will store a lot of energy. If it breaks people may get hurt and things may be damaged. That is why the tugger manufactures specify a very expensive rope for pulling purposes. It is a static rope with little stretch and will not store much energy. The type of rope shown in the photo it dynamic and may stretch 10 to 15%. This also creates danger to the feeder as the conductors tend to "jump" into the conduit when using a dynamic rope. The rope stretches until the weight of the cable and the friction is overcome and then as the rope returns to close to its normal length, the conductors jump into the raceway. It can take the feeders fingers with, if he is not careful.
