The most interesting part of the crane segment and also the largest volume is container cranes. There is two types Ship to shore cranes (STS) and rubber tired gantry cranes (RTG).
In general the crane specifications are based on ISO 12944. The normal specification is one coat of a zinc based shop primer, 1 -2 coats of epoxy mastic and 1-s coats of polyurethane topcoat. The internal surfaces are normally just one coat of an epoxy coating. This can be varied based on the location and customer requirements.
JGC has developed a selector based on the ISO 12944 standard and it is identical to the one for bridges and external storage tank surfaces.
