Summary: | The invention discloses an electric self-driving shear fork lifting device and a control method of the electric self-driving shear fork lifting device. A control circuit of the electric self-driving shear fork lifting device comprises a controller, a main contactor KM1, a first pump contactor KM2, a second pump contactor KM3 and a steering contactor KM4. The controller has two working modes of a platform mode and a ground mode, a port P15-1 of the controller is a platform mode port, a port P12-1 is a ground mode port, and the platform mode and the ground mode are switched by a key switch SH. The terminal M1- and the terminal M2- of the controller are connected in series to provide the negative pole of a lifting pump MP, 24V power is provided by the positive pole by connecting two groups ofdirect-current 12V batteries in series, and the manner is different from a traditional manner of using only one group of 12V power, so that the long-term unbalanced use of the two groups of batteriesis avoided, and the servi |
