To install the crane span before installation, camber, level of metal structure of main girder bending, trolley rail height difference, gauge deviation, diagonal bridge survey.

安装前要对起重机安装跨度，金属结构主梁的拱度、水平旁弯，小车轨道高低差、轨距偏差，桥架对角线等进行测量。

The elastic rigidity of rail pad and ballast stiffness of rail and clamping force of fastener are the main factors that cause the widening of gauge.

钢轨垫层和道床的刚度、轨刚度和扣件扣压力是影响轮轨之间作用力和轨距扩大的主要因素。
