PROBLEM TO BE SOLVED: To provide a load receiving platform lifting apparatus capable of remarkably reducing burden of wiring operation. SOLUTION: The load receiving platform lifting apparatus is provided with a load receiving platform 5, drive devices 14, 20 for operating the load receiving platform 5, a marker lamp 60 having a coil 61 arranged at the load receiving platform 5 and generating induced electromotive force by receiving an electric wave and a light emitting means 63 which emits light with a current flowing through the coil 61, a power source switch 58 for turning on and off a power source of the load receiving platform lifting apparatus 4, operation devices 27, 46 for specifying operation of the load receiving platform 5, and a controller 45 to which operation signals are inputted from the operation devices 27, 46 to output command signals for instructing the operation of the drive devices 14, 20. The controller 45 is provided with input parts 50, 51 for inputting the operation signals from the operation devices 27, 46, a calculation part 53 for generating a light emission signal based on the input of the power source through a power source switch 58 or the operation signals from the operation devices 27, 46, and a transmitting part 55 converting the light emission signal generated at the calculation part 53 into an electric wave and transmitting it to the marker lamp 60.
