This export project includes two sets of 40 ton dock container cranes and 3 sets of wheel-type gantry cranes. 这个出口项目包括两台四十吨岸边集装箱起重机和三台轮胎式龙门起重机。
The container crane dynamic load coefficient dynamics model is built and its analytical result by the method of modal analysis is achieved. 摘要建立确定大型岸边集装箱起重机起升动载系数的动力学模型,并用模态分析法求得其解析解。
