Bridge Construction in Zaporizhia

It took over three years to successfully finalize the delivery of two NOV 1532 UP F6 hoists, which are now working on the construction of the giant bridge across the Dnieper in Zaporizhia, Ukraine.

The bridge is being built by the specialized Ukrainian company Mostobud, and it is special due to the height of its main pylons, which is up to 150 m above the river level. Both the pylons, used for suspending the bridge structure, are in the middle of the river, so we had to figure out on what the hoists would be assembled. For this purpose, the customer provided steel platforms mounted at the foot of each of the pylons. They had to be of sufficient size to carry not only the static load of the 145-metre-tall hoist mast, the cabin and the cargo, but also the load of the dynamic shocks caused by the movement of the elevator cabin.

When choosing from our wide model range, the customer picked a hoist with a capacity of 1500 kg. Given the working height, another requirement was made for a speed above 60 m/min. Another special feature was the shape of the pylons, which did not permit placing the hoists at the same distance from the pylon. As a result, we had to make a number of non-standard tie-ins, the longest of which is over 5 metres long, and the entire mast inclines at nearly 5 degrees. The length of the tie-ins called for a special tipping platform on the elevator roof for easier access to the tie-in points along the wall.

The hoists are used for transporting both persons and materials to the slip form. For this purpose, the hoist has to be installed with its side to the wall, not facing it as would be customary. To avoid having to prepare a special platform for entering the forms, the cabins have a side door with an exit platform directly onto the lower level of the formwork. The application had been successfully tested in our previous projects. Thanks to a wealth of experience, we thus managed to implement a project that features a number of technical specialities in a single hoist delivery.
