近两年,随着国家经济形势的进一步好转,基础建设力度不断加大,汽车起重机行业进入了一个难得的快速增长期,2002年实现销售6700台,但从产品结构上来看,其中进口产品300台,绝大多数为大吨位产品。因此,在某种程度上,中国未来汽车起重机市场的竞争,就是大吨位产品的竞争。 相似文献

Optimal locations of mobile cranes in a construction site amongst known obstructions and boundary limits taking into account dimensions of the cranes, are evaluated and calculated on a construction site plot plan. A general algorithm has been developed to determine the workspace area in the construction site by preselecting data input satisfying the required crane-fitting distance and by calculating the crane body area to a given clearance distance. For each lifted object, the crane minimum and maximum radii based on capacity are overlaid on this work area to produce the feasible mobile crane position area. This is the first function of an automated crane selection and positioning program that runs independent of a CAD (computer aided design) system. The algorithm is implanted in the industry partner's crane application and a case study is presented demonstrating the benefit of the algorithm. 相似文献

Automated Path Planning for Mobile Crane Lifts 总被引:1,自引:0,他引:1

Planning the lift path of a crane is an important subtask within the heavy–lift planning process. This paper reports the work done toward applying configuration space (C–space) and search concepts to develop a tool to identify lift paths that satisfies the planning requirements. The C–space is generated using an interference detection technique. Two levels of heuristic search are performed within the C–space. The first search is a heuristic depth search to determine the obstacle–free lift paths. The second search performs a more detailed optimization of the path within a constrained search space. The tool can be used within the AutoCad environment and is based on program modules developed using AutoLisp and external programs. The system was tested on a number of problems. It was found that the system was capable of generating good paths in complex situations. 相似文献
