FAQ

Q1: What is FEM standard double girder gantry crane?
It is a European heavy-duty gantry crane designed according to FEM/DIN fatigue standards. The double box girder structure supports larger load, longer span and higher working cycle than conventional gantry cranes, specially built for high-standard industrial projects.
Q2: What is the difference between FEM single girder and double girder gantry crane?
FEM double girder type supports heavier tonnage, longer span, higher FEM 4m/5m super-duty grade and dual hook configuration, suitable for continuous heavy-load industrial work.
Q3: Can you provide FEM calculation report for bidding?
Yes, we provide official FEM working cycle calculation documents, structural fatigue analysis and full technical files for project tender and approval.
Q4: Does FEM double girder gantry crane support custom span and tonnage?
Fully customizable. We design exclusive solutions according to your site span, lifting height, load capacity and working frequency.
