OVERHEAD CRANE

 DOUBLE GIRDER

    Double Girder overhead cranes are suitable for industrial applications where very heavy weights. It should
    have a width ranging from 6-30 meters and should weigh raised from 3.2 tonnes to 32 tonnes as standard,
    which are electric hoists for lifting beam pairs designed, manufactured as standard models already used for
    putting  on the crane. Double Girder by appropriate and safe for double girder overhead crane with a lifting
    power of the popular inferior to single-beam overhead cranes. It is mostly used for large industries. Which
    is not very compared to small-scale industries and the structure of the crane is a double girder crane has a total
    weight of more than a single beam of the crane used to lift an equal weight. The refore, the more burdensome
    for the fabrication plant. But  if you want to use electric cranes  to lift heavy weights. Or a very large crane
    overhead cranes beam pair is more appropriate during the structures that are stronger and more secure. And
    with regard to speed of deployment of the crane. This should be a two-speed pace is slow rhythm. And speed
    in the same direction As overhead cranes All single-beam But when larger crane. It should be used at a slower
    speed, small cranes. For work safety

      For general use the term needs to raise approximately 6-12 meters long, measured from floor to hook up the
    beam up to this kind of electric cranes.
