The RIALEX model SPD double-girder overhead travelling cranes are characterised by high lifting capacity and a stable and robust design. This type of overhead cranes uses welded box girders, on which we place top-class wire rope winches. Overhead cranes are available in many variants, from standard to more technologically advanced options. This type of crane design allows for the construction of complementary structures such as repair platforms or crane cabins. Thanks to the optimal selection and use of the highest quality components by our engineers, we guarantee extended service life of overhead cranes and complete safety during operation.
