标准过时、尺寸不足、设备老化，老旧机械车位改造迫在眉睫

Core Insights - The article discusses the challenges and opportunities associated with mechanical parking systems, particularly in urban areas where parking demand is high and vehicle sizes have increased over time [1][3][12] Group 1: Current State of Mechanical Parking - Many mechanical parking systems were built 10 to 20 years ago and are now outdated, unable to accommodate larger vehicles such as SUVs and electric cars [1][12] - A significant number of mechanical parking spaces are underutilized, with an average idle rate of 42% across the industry, and in some residential and commercial areas, this rate exceeds 60% [12][14] - The total number of mechanical parking spaces in China is projected to reach 9.85 million by the end of 2024, but the economic loss due to underutilization is estimated at 8 billion RMB annually [12][14] Group 2: Upgrades and Modifications - The Silver Island Business Building recently upgraded its mechanical parking system, increasing the number of spaces from 51 to 104 and expanding the dimensions of the parking spots to accommodate larger vehicles [3][5] - The upgrade was funded through government investment and aimed at improving parking availability for both office workers during the day and residents at night [5][14] - The Beijing Municipal Government has issued guidelines to encourage the renovation of mechanical parking systems, allowing for simplified procedures and potential financial support for upgrades [14][15] Group 3: Challenges in Renovation - Renovating mechanical parking systems poses challenges, including the need for significant financial investment, as costs can reach hundreds of thousands of RMB per project [14] - Many existing systems are constrained by building height limits and outdated designs, making it difficult to expand or modify them without extensive reconstruction [13][14] - The lack of maintenance and outdated technology in many mechanical parking systems has led to a high rate of disuse, with some systems being completely non-functional [10][12]
