The invention discloses a hot rolled steel coil rear-mounted transportation device and method, and belongs to the field of control. An output signal of each steel coil position sensor and the working state of the coil feeding position, the coil discharging position or the conveying chain unloading point of each stepping beam are introduced into an on-site PLC (Programmable Logic Controller); establishing a corresponding logic interlocking relationship in the PLC; when the previous stepping beam conveys a steel coil to the coil feeding position of the next stepping beam, a completion identification signal is generated, meanwhile, a corresponding steel coil position sensor detects an occupying signal of the steel coil, and after the two signals are obtained by a PLC, the station of the next stepping beam is set through a rising edge signal; therefore, the position information of the transported steel coils is displayed on the operation picture HMI of the PLC, and the positions of the transported steel coils are
