移动式起重机. 稳定性的测定

[中文适用范围]： 本国际标准规定了通过计算验证移动式起重机稳定性时要考虑的条件，假设起重机在坚固且水平的表面（坡度不超过 1%）上运行。 它适用于 ISO 4306-2 中定义的移动式起重机，即安装在轮子（轮胎）或履带上的设备，无论有或没有支腿，随车起重机除外。 [外文原描述]： ISO 4305:2014 specifies the conditions to be taken into consideration when verifying the stability of a mobile crane by calculation, assuming that the crane is operating on a firm and level surface (up to 1 % gradient). It applies to mobile cranes as defined in ISO 4306-2, i.e. appliances mounted on wheels (tires) or crawlers, with or without outriggers with the exception of loader cranes.
