The price of an APS is primarily driven by the system type (Tower, Puzzle, or AGV-based) and its lifting capacity. Buyers should ensure the system supports a minimum load of 2,500kg per space to accommodate modern SUVs and EVs. Key technical drivers include PLC control systems (e.g., Siemens or Mitsubishi) for reliability, variable frequency drives (VFD) for smooth motion, and galvanized steel structures to prevent corrosion. Always verify the retrieval time, which should ideally be under 90-120 seconds to ensure user efficiency.
