Factories that move heavy parts, moulds, coils or machinery usually need an EOT crane. In a PEB industrial shed, the crane runs on girders carried by the building's own columns, so the crane and the building have to be designed together.
Get it right and the crane runs smoothly for decades. Get it wrong and you end up with a shed that is too low, columns that need strengthening, or a crane rated below what the line needs.
6 Things to Decide Before You Order
These inputs set the size of the crane girders, columns and foundations. Share them with your PEB manufacturer at the enquiry stage, not after the drawings are approved.
The heaviest load you will lift, in tonnes. Size for the realistic maximum, with some headroom for future work.
The distance between the two crane rails. It is set by the building width and column layout.
How high the hook must lift above floor level. This, plus the crane's own depth, drives the shed's eave height.
How often and how heavily the crane works. A crane in daily heavy use needs stronger girders than one used for occasional maintenance lifts.
Two cranes in one bay, or cranes in adjacent bays sharing a column, change the loads the frame must carry.
The crane supplier's wheel loads are the most accurate input for designing the runway girders. Share them as early as possible.
