The Çanakkale 1915 Bridge is a suspension bridge in the Çanakkale Province in northwestern Turkey. With the main span of 2,023m the bridge surpass the Akashi Kaikyō Bridge in Japan by 32m to become the longest suspended span in the world when completed in 2022.

The temporary walkway and PPWS main cables were erected using the above erection winch system supplied by DLT Engineering. The system comprises two looped erection ropes, one for each PPWS main cable, with a pair of constant tension driving winches and rope reeling/unreeling drums for each erection rope. The two driving winches and rope reeler/unreelers for each looped erection rope were located adjacent to the main cable anchorages as shown in the video above. The erection rope was supported along its length using gallows frame rollers above the temporary walkway and roller wheel frames above the pier top saddles and above the splay saddles.
