A continuously supported crane track is characterised by rails mounted on a continuous steel sole plate with a continuous under cast, which may or may not be mounted in a concrete channel. This system is very suitable for high dynamic wheel loads.
If the wheel load is half of the maximum allowed wheel load on the rails, there is a possibility to omit the steel sole plate. The rail is then anchored to concrete with anchor bolts through the rail foot. The special features are the drilled holes in the rail foot and the continuous underlay. This system is only suitable for crane rails with a wide base (type A).
