An electronic remote control limiting system is disclosed, comprising limiting devices which are mounted on an elevating ladder, wherein the limiting devices are connected with emitting devices, emission signals are received through receiving devices, control signals are emitted through the receiving devices to a an electric motor control loop while alarm signals are emitted to an audible and visual alarm device, and the output of the electric motor control loop is connected with the electric motor. The electronic remote control limiting system is characterized in that the limiting devices are adopted for detection of the ascending limit position, signal collection and signal control are accomplished through employment of the emitting devices and the receiving devices, two identical device sets are adopted, stability and reliability are guaranteed through adoption of double-way four-channel cross control, the power supply is cut off in time, and accident occurrence is completely eradicated. The electronic remote control limiting system is advantaged by safety, reliability, and convenience of use.
