When procuring a Lift Sliding Parking System (PSH), you must prioritize structural integrity and motor reliability. Key specs include a lifting capacity of at least 2,000kg to 2,500kg per space to accommodate SUVs. Ensure the lifting speed is between 8-12m/min and sliding speed is 7.5-10m/min for operational efficiency. The steel structure should be hot-dip galvanized to prevent corrosion, especially for outdoor or basement installations. Additionally, verify the use of PLC (Programmable Logic Control) systems (e.g., Siemens or Omron) for stable automated sequencing.
