The price of a car turntable is primarily driven by its load capacity, diameter, and drive mechanism. For residential use, a 3,000kg to 5,000kg capacity is standard, while commercial displays may require more. Ensure the unit features a Pin-Gear drive system rather than a friction drive for smoother rotation and longer lifespan. Additionally, the platform thickness (usually 6mm-10mm) and the use of hot-dip galvanized steel for corrosion resistance significantly impact the long-term value and initial cost.
