The invention discloses a single-handle electrical control system of a transporter grab crane. The single-handle electrical control system comprises an electrical transmission mechanism I and an electrical transmission mechanism II, which cooperatively work to acquire opening, closing and lifting state information of a crane grab to control the grab work, and further comprises a PLC (Programmable Logic Controller) controller in data communication with the electrical transmission mechanism I and the electrical transmission mechanism II, wherein the PLC controller calculates and outputs a rope difference between the two transmission mechanisms according to the operation distances of the electrical transmission mechanism I and the electrical transmission mechanism II, and then compares the rope difference with a limiting reference value to determine the actual opening position of the grab, so as to control the grab work. The system adopts the independent electrical transmission mechanism I and electrical transmission mechanism II to monitor the crane grab state in the working process in real time, calculates the rope difference value between the two transmission mechanisms, and compares the rope different value with the limiting reference value to determine the opening position of the grab, so as to control the grab work.
