When sourcing wardrobe lifts, the most critical factor is the load capacity, typically ranging from 10kg to 20kg. You must ensure the pneumatic or hydraulic buffer system is tested for at least 50,000 duty cycles to guarantee longevity. Additionally, verify the adjustable width range (e.g., 450-600mm, 600-830mm, or 830-1150mm) to ensure compatibility with standard cabinet dimensions. The crossbar should be made of high-strength aluminum alloy or chrome-plated steel to prevent bending under weight.
