A rolling base assembly for truck cranes which allows movement of the truck crane under load-carrying conditions. The device comprises a fixed chain installed along the centerline of a flatbed trailer. A rolling base, having outboard roller housing assemblies, is caused to crawl along the fixed chain by means of motor driven sprocket devices attached to the rolling base. The roller housing assemblies are designed to move along the standard I-beam construction of a flatbed truck.
