稳定性是轮式起重机的重要特性指标。起重机具有足够的稳定性,一是取决其自重大小及是否合理分布,二是取决于起重作业的工况如起重量、幅度、作业场地条件、风力、附加动力负荷作用等因素单独或组合起来是否会引起翻倒。在计算方法上,长期以来国内存在许多不同意见,如何试验也不够明确,考核也没有统一的标准。现将标准JB 2629—79《汽车起重机和轮胎起重机技术条件》中关于这一问
Stability is an important characteristic index of wheeled cranes. The crane has enough stability. First, it depends on the size of its own weight and whether it is reasonably distributed. Second, it depends on the conditions of the lifting operation such as the weight, amplitude, work site conditions, wind force, and the role of additional power load, alone or in combination. Will it cause an overturn. In terms of calculation methods, there have been many different opinions in the country for a long time. How to test is not clear enough, and there is no uniform standard for assessment. The standard JB 2629-79 “Technical conditions of truck crane and tire crane”
