The utility model relates to vehicle parking equipment in the traffic industry, and particularly relates to three-dimensional parking equipment with a single upright column and double parking positions. The three-dimensional parking equipment comprises components including a guide track (26), a walking wheel assembly (2), a walking chain wheel (10), a walking motor (9), a vehicle-loading board (12), an elevating motor (31), a rotary motor (29), left and right transverse beams (16 and 46), a transverse beam (43), front and rear upright columns (24 and 4) and the like. The three-dimensional parking equipment is reasonable in structure, small in occupied space, low in production investment cost, convenient to use and has the functions of wind resistance, quake resistance and corrosion resistance; and the requirement that multiple vehicles can be parked with few parking equipment is met.
