全地面起重机一般安装4个垂直支腿和4个水平支腿。其作业范围宽广,作业环境复杂,振动、温度和电磁干扰等均可引起计算机网络输入、输出、通信等环节发生故障,致使支腿无法按照设定的方式运动,造成起重机无法完成吊装作业。本文以起重机左后垂直支腿无 All-terrain cranes typically have 4 vertical outriggers and 4 horizontal outriggers. The wide range of work, complex operating environment, vibration, temperature and electromagnetic interference can cause computer network input, output, communication and other aspects of failure, resulting in the legs can not be set in accordance with the set movement, resulting in cranes can not be completed lifting operations. This article has a crane left vertical leg without
