What is the FEM duty class of a crane?

<p>The FEM duty class (FEM 9.511) is a European standard that classifies cranes based on the number of operating cycles and load spectrum. It determines the structural and mechanical design requirements for components like the hoist, trolley, and girders. Common classes include FEM 1Am (light), 2m (medium), 3m (heavy), and 4m (very heavy).</p><p>At Chunhua Grúa Export, we manufacture cranes from 0.5T to 150T across 81 standard models, all certified to CE and other international standards. We can supply cranes in any FEM duty class (1Am to 4m) to match your application—whether for steel mills, ports, or general manufacturing. Our engineers will help you select the correct class based on your duty cycle and load profile.</p><p>For a tailored quote within 4 hours, contact us on WhatsApp at +86 19392777259.</p>
