摘　　要：对轮武起重机整机稳定性决定的起重能力的计算进行了讨论,并对在不同工况和不同臂长条件下,按照整机的重心轨迹法进行计算的对比和相对误差分析。在此基础上,提出了轮式起重机在考虑两个方向吊重所受风力和吊重水平惯性力时,整机稳定性决定的起重能力的简化计算方法。The lifting capacity calculation dependent on overall stability of wheel type crane is discussed and compared with the calculation based on the trajectory of the gravity center of the machine under different operating conditions and various reaches with their and relative errors are analyzed. On the basis of above work, a calculation method for lifting capacity dependent on overall crane stability is presented with the wind force on the load in both directions, and the horizontal inertial force of the load taken into account.
