Double overhanging designs extend hook coverage by 30-50% beyond support rails, eliminating workstation dead zones
EN 15011-compliant box girders withstand 25% higher dynamic loads than traditional I-beams
Integrated anti-sway AI reduces load oscillation by 90% at 40m/min speeds
Modular power systems enable outdoor operation with 98% weather resistance
Predictive maintenance sensors cut repair costs by 35% and extend service life to 25+ years
European double overhanging single-beam cranes revolutionize floor space utilization with cantilevered girder extensions at both ends. Unlike conventional cranes constrained by runway limits, this design achieves 15-25m hook coverage beyond support rails – reaching workstations traditionally requiring auxiliary equipment. The secret lies in reinforced monobox girders fabricated from high-tensile steel (S355JR grade), distributing stress evenly across unsupported sections while meeting EN 15011 fatigue standards.
