The invention provides an overhead working
truck, a control method, a control device and a
machine readable storage medium. The method comprises the steps that an operation instruction is obtained; under the condition that an operation instruction is received, whether the current inclination angle of the frame, the
current load of the working platform, the actual operation range of the overhead working
truck and the current oil
cylinder pressure of the multiple supporting leg structures meet operation conditions or not is sequentially judged according to a preset sequence; and determining that the current inclination angle, the
current load and the actual operation range all meet the operation conditions and each current oil
cylinder pressure does not exceed the preset
pressure range, and controlling the overhead working
truck to operate according to the operation instruction. On the premise that the current inclination angle, the
current load, the actual operation range and each current oil
cylinder pressure all meet the operation conditions, it is judged that the overhead working truck has enough stability, the judgment precision can be ensured through comprehensive judgment of the four conditions, and therefore unnecessary action limitation is avoided, the operation range of the overhead working truck can be greatly widened, and the working efficiency is improved. And the frequent vehicle moving probability is reduced.
