Applying the software ADAMS for dynamic simulation and Pro/E for three-dimensional design creates the mechanical system of virtual prototyping model of the 200t crawler crane. The models of the drag bar, the spring backstop, the luffer rope and the crawler in the system are established well by ADAMS/View module. The dynamic simulation of the complete mechanical system is researched at series of work condition, which occurs possibly the crawler crane boom backward tipping as the crawler crane unloads suddenly.
