Transport & Mobile Crane Logistics: From Factory Gate to Final Placement
Highway oversize load envelopes, escort vehicle regulations across Europe, Ro-Ro maritime shipping, and mobile crane capacity sizing based on reach radius and wind speed limits.
1. The Transport Dimension Chain: Module, Packing, Trailer & Route Clearances
A module's nominal width of 3.0 m is not its final shipping footprint. Exterior protective tarping, lifting shackles and flashing overhangs expand the load by 10-15 cm. Coupled with a low-bed trailer bed height (typically 0.60 to 0.90 m), an interior ceiling of 2.60 m translates to an overall road transport height of 3.80 to 4.10 m.
European highway codes classify loads exceeding 2.55 m in width as special transport (convoi exceptionnel / Großraumtransport), requiring dedicated route permits and escort pilot vehicles depending on the transit country.
2. Mobile Crane Sizing: Weight, Reach Radius & Ground Bearing Pads
A 100-ton crane does not lift 100 tons across the jobsite. Crane load charts are dictated by reach radius: a 12-ton modular box lifted at a 22-meter distance frequently demands a 160-ton or 220-ton all-terrain crane.
Furthermore, crane outrigger leg reaction pressures can exceed 400 kN. Certified timber or steel outrigger mats must be deployed to distribute ground pressure safely, and lifts must be suspended whenever sustained winds exceed 12 m/s.
