建筑技术和动力机械制造工艺的进步,使水电站和水轮发电机组的容量不断在增长。机组单机容量的增长,势必会加大安装部件的重量、相应地需要安装与使用具有更大起重能力的天车设备。例如:布拉茨克电站装二台350吨天车;克拉斯诺雅尔斯克电站装二台500吨天车;格列古力Ⅱ级电站的天
Advances in building technology and power machinery manufacturing processes have led to ever-increasing capacity of hydropower stations and hydroelectric generating units. The unit capacity growth, will inevitably increase the weight of the installation of components, the corresponding need to install and use crane equipment with greater lifting capacity. For example: Bratsk power station installed two 350-ton overhead crane; Krasnoyarsk power station installed two 500-ton overhead crane; Gliculi II power plant days
