The invention discloses a transferring device for a heavy object. The transferring device comprises a base, a vertical rod, a lifting motor, a screw rod, a big screw cap, a translation motor, a worm, a worm wheel, a gear, a gear rack, a moving plate, lower roller wheels, upper roller wheels, an upper pallet, a lower pallet, a middle pallet, a cushion block, a storage battery, a switch box and so on. A reversible switch, a lifting switch and a translation switch on the switch box can control start, end, a rising mode and a lowering mode. The lifting motor is started to drive the screw rod to rotate during a rising period, the heavy object is put on the upper pallet to rise, and stops when rising to an upper step, the translation switch is switched on, the translation motor drives the worm wheel, the gear and the gear rack to translate by the worm, and the gear rack drives the moving plate to perform translation, so that the heavy object is moved forwards, stops when being moved to an upper step surface, and then is moved onto another step. Procedures are reverse during a lowering period, and by the circulation in this way, the heavy object can be risen or lowered one step by one step.
