Design to FEM / DIN / ISO / IEC
A bought engineering service: calculation, drawings and duty group to FEM, DIN, ISO and IEC before anyone fabricates.
This page sells standards engineering as a scope of work. SWL, span, height of lift and duty are the inputs. Mechanical calculation follows FEM and DIN practice. Electrics follow IEC. ISO references sit on the same pack where the project calls for them. The drawing set includes runway reactions for the civil engineer. It is not the journey page that tells the story of drawings before our own shop cuts plate.
When it fits
Buy this service when you need a signed calculation pack — a new crane, a rival girder you will keep, or a civil engineer who will not accept a sketch. You do not have to buy fabrication from us to buy this sheet.
Duty and steel
Duty group is the first output, not a sticker. We will not apply a warehouse FEM class to a process hook because the tonne figure looked similar.
Interface
The pack names rail centres, wheel loads, pendant or radio, and festoon versus conductor bar. ISO/IEC clauses that the inspector will ask for are listed, not implied.

Journey drawings before cut live at process/engineering-design. Fabrication is a separate service. Duty as a company capability lives on the about page.
