FAQ: Crane Systems and Loads in Pre-Engineered Buildings

Integrating Cranes into Your PEB

Overhead cranes are vital for many heavy manufacturing and workshop operations. Designing a PEB to support these cranes requires careful consideration of dynamic loads.

What types of cranes can be installed in a PEB?

PEBs can support various types of cranes, including Electric Overhead Traveling (EOT) cranes, underhung cranes, monorails, and jib cranes. The capacity can range from 1 ton to over 100 tons, depending on the custom engineering of the primary frames and crane beams.

How do crane loads affect the building design?

Cranes introduce significant dynamic loads: vertical impact loads from lifting, lateral loads from the trolley moving across the bridge, and longitudinal loads from the crane traveling down the runway. The building's columns, foundations, and bracing systems must be robustly designed to absorb these forces and prevent excessive sway.

Can I add a crane later if I didn't plan for it initially?

Adding a heavy EOT crane to an existing PEB not originally designed for it is very difficult and costly. It typically requires independent crane columns and extensive foundation modifications. Always account for potential future crane requirements during the initial design phase.
