FUD double-girder top running grab overhead crane at Cemex Rudniki

  • Published in News

CEMEX, a world leader in cement, aggregate and ready-mixed concrete solutions, was recently supplied with a specialist machine made by Fabryka Urządzeń Dźwigowych S.A. A double-girder top running grab overhead crane was installed in Rudniki cement plant.

FUD's overhead crane is working in the raw materials warehouse in Rudniki. It is used to transport materials such as: broken limestone, granulated blast furnace slag, lump slag, natural sand, burnt shale, boiler slag, Bessemer slag. The crane was made according to the Client's requirements and needs. The overhead crane with lifting capacity 10t, span of 30m and lifting height 20m has a grab with volume 3.2m3 and is controlled via controller/resistor using FUD gear.

What were the specific requirements of CEMEX for the construction of double-girder top running overhead crane?

"We had to take into account the intended use of the crane in a specific environment which is a cement plant: high dust level, high temperature of the transported material. On top of that, the equipment is used 24 hours a day. Hence, we used A8 subassemblies which are meant for high intensity working conditions and are characterized by high resistance to failure" - comments Wojciech Wójcik, FUD S.A. Sales Director

CEMEX is one of the key Clients of FUD S.A. with a long history of cooperation. Waldemar Zabłocki - Production Director emphasises that "The overhead crane for Cemex is an excellent example of how a Client can be attached to the good traditions of the FUD company. Technical solutions which the Client required were used 30 years ago. Our Client was very "keen" on using exactly the same solutions and explained: since I already have overhead cranes made by your company which have been running without failure for 30 years, then I want another crane which is exactly the same as the previous ones".

This is the best recommendation for the company which manufactured over 12,000 overhead cranes and 550 dock cranes in its over-100 year history.
