UK-based TensionPro has supplied a range of special bolting tools for constructing the world's longest mid-span suspension bridge, Çanakkale Bridge, in north-west Turkey.
The 4,608m bridge, which spans the Dardanelles Strait, has a mid-span length of 2,023m and tower heights of 318m. TensionPro has supplied 160 hydraulic bolt tensioners complete with 16 electric pumps, hoses and manifolds. The large volume order included special M42 spring piston return tensioners with bespoke spherical seats to compensate for any misalignment issues, together with specially designed 1500 bar high flow electric pumps with a digital pressure setting and pressure read out. The tools use a remote control pendant for safe and easy operation.
Armed with TensionPro's tools, construction workers can tighten the suspension bridge cable bands and ensure high loads are achieved with extreme accuracy. The hydraulic system is designed to power multiple tools at once. All TensionPro's products are put thorough a stringent in-house testing procedure before being shipped to ensure smooth operation once on site.
To secure the contract TensionPro had to guarantee a quick turnaround on production and delivery. The UK team was supported by the company’s local representative NETRATEK who supplied commissioning, training and service support.
