设计轮式起重机时,必须明确该起重机的作业性能和重量、尺寸等方面的具体要求以及在作业时所承受的各种载荷。使用起重机也需要了解该起重机的全部参数和设计时假定的载荷状况,以便让使用者能更好地使用并能充分发挥它的全部性能,同时避免事故的发生。 When designing a wheeled crane, it is necessary to clarify the specific requirements of the crane in terms of work performance, weight, size, etc., as well as the various loads that are applied during operation. The use of a crane also requires knowledge of all the parameters of the crane and the load conditions assumed at the time of design, so that the user can use it better and fully exploit its full performance while avoiding accidents.
