What is difference between crane girder and gantry girder?
The gantry girders are girders which supports the loads that are transmitted through the traveling wheels of the crane. The crane girder spans from column to column, this usually do not have any lateral support at the intermediate points excepting when a walkway is formed at the top of the girder.
Why plate girder is used?
A plate girder is used when we need deeper sections having higher stiffness to carry heavy loads. Further, there is a limitation in producing a hot-rolled section when the depth of the section is increased. Therefore, we have to use built-up sections that can carry large bending moments and shear forces.
