    Slideway in crane boom
    Material
    ZX-100K
    Description of the application
    In this application, a suitable bearing material for the storage of the telescopic boom has been searched. The slideway is located in the rectangular guiding tube in which the boom is guided.
    Problem
    For esthetical reasons the lacquer mating surface of the boom must not be damaged by the sliding movement The bearing is also subjected to the weather conditions and direct sunlight exposure. There is a high surface pressure, caused by edge pressures. In addition vibrations and impacts occur during the drive. Dry running, very low wear on the slideway, no damage to the lacquer mating surface, tight thickness tolerances and absolute dimensional stability are also required.
    Problem-solving
    Slideways made of ZX-100K are now used. In addition, the boom was painted with a modified colour.
    Working life
    After extensive tests of more than 40 materials, ZX-100K has been chosen and it is now used as standard feature. In the future, also other bronze bearings should be changed with the ZX-100K ones.
    Advantages
    Even under load with ZX-100K slideways, an extension of the telescopic arm is possible. Preservation of the painting.
    No problems for outdoor use and low maintenance thanks to dry running conditions.
