摘　　要：关于高空作业车辆稳定性的国家标准主要有适用于举高消防车的GB 7956.12-2015和适用于高空作业车的GB/T 9465-2008两种.为探讨高空作业车稳定性校核的合理方法,以某22 m云梯车为例,分别按照这两种标准的要求进行计算和对比.结果表明:相比于举高消防车标准,高空作业车标准对高空作业车辆稳定性和安全性的理论计算方法更加保守,安全性更高,但限制了车辆的工作范围,不能完全发挥车辆的作业能力.结论认为:在对高空作业类车辆进行设计计算时,若对车辆稳定性和安全性要求非常高时,建议采用高空作业车标准的计算方法,否则建议采用举高消防车标准的计算方法.There are two copies of the National Standards,i.e.GB 7956.12-2015 and GB/T 9465—2008 applicable mainly to govern stability of aero work platform trucks--basically the firefighting wagons,and aero working vehicles,respectively.In order to investigate into stability of aero working truck to get reasonable checking ways,it has to take a firefighting truck with an aero ladder for instance so as to carry out computation and comparison therewith,respectively.The results show that the standard for the aero working truck is more conservative,but safer than the standard for up-lift firefighting truck,except limiting the truck’s operational range and could not fully use the truck to the full.A conclusion comes out as that it is recommended to use the computing method of the standard for aero working truck for very high reliability and safety requirements,or otherwise utilize the computing method in the standard for uplift firefighting truck.
