摘　　要：介绍了牵引式小车架精度控制要求和方案,通过改进小车架结构件制作、划线、机加工方法,提高加工精度,保证小车架重要机加工尺寸的要求,避免小车使用过程中可能出现的轴承碎裂、运行异响、跑偏啃轨等现象,从而延长起重机设备的使用寿命。In this paper, the requirement for controlling the machining accuracy of the traction trolley frame and its controlling scheme are introduced. The equipment machining accuracy is increased by improving the fabricating, marking, and machining methods of trolley structure to ensure the precise control of dimension accuracy of important structural parts. Through this way, the possible faults such as bearing fragmentation, abnormal running noise, deviation and rail gnawing are avoided in the trolley working process, so that the service life of the crane equipment is prolonged.
