5. In order to prevent the attacks of storms, there are reliable wind-shielding devices such as rail clamp, ground anchor.
 
crane girder:
the crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!
