Positive Safety Initiative - four way cable

4wayroller2

Overview

During early stages of the project there was an issue around suitable cable rollers to pull the hundreds of kilometers of cables required for the project. Commercially available rollers are of a single roller design, because of this and the lengths of the cable runs up to 14 people would have been required for some of the cable pulls to ensure the cable did not come off the roller. There was also a hazard for the person stationed by the rollers of being struck by the cable if it did flick out of the roller. Tee came up with an idea of using a 4 way roller system to keep the cables contained within the roller.
