桅杆起重机是吊装大型设备的简易装备 ,它的特点是设备构造简单 ,价格便宜 ,拆装方便。由于其主体结构采用标准节组装的桁架结构 ,起升高度较大 ,所以多用在石油、化工行业的安装工程中。采用有限元可视计算能较真实地模拟结构计算模型 ,解决手工计算不能解决的空间结构超静定 Mast crane is a simple equipment lifting large equipment, which is characterized by simple structure, low cost, easy disassembly. Because of its main structure using the standard section assembled truss structure, lifting height, so it is used in petroleum and chemical industry installation. Using finite element visual calculation can more accurately simulate the structure of the calculation model to solve the manual calculation can not solve the spatial structure of statically indeterminate
