Justify Larger Wheel Load Capacity

Larger cranes mean larger wheel loads, and upgrading rail girders to carry them is expensive. But existing girder systems often have more capacity than they are rated for. In this presentation, Erik Soderberg and Arun Bhimani explain how to justify that additional capacity through refined structural analysis, analysis of pile driving records, and load testing. This can provide a practical alternative to upgrades. Of the roughly 20 girder capacity studies Liftech has performed, about 90% justified increased capacity.
