The invention relates to a handling robot, in particular to an intelligent mechanical three-dimensional garage using clamping tires of the handling robot to lift cars (or similar goods) and carry out front-back bi-directional carrying-depositing actions. The mechanical three-dimensional garage consists of a handling robot, a car storage place, a carrier, a loading platform, and a platform rail. The handling robot includes two moving trolleys in front and back sides, a retractable device is arranged between trolleys. The moving trolley comprises a trolley rack, a moving mechanism, clamping arms, a steering wheel assembly and an oil-way circuit slewing mechanism. According to the handling robot and a mechanical three-dimensional garage using the handling robot, problems of depositing cars in limited space are solved, automatic positioning of tires of cars with different wheelbases is flexibly realized, and the front-back bi-directional carrying-depositing actions are achieved. Besides, a moving drive mechanism can be independently installed on the loading platform to suitable for a flat mobile type parking system, and a lifting mechanism can be installed on the loading platform with the moving mechanism to suitable for an aisle-stacking parking garage, so as to realize three-dimensional movement of objects.
