Current common mechanical parking equipment with lifting and transferring, vertical circulation, multi-loop, horizontal circular, flat mobile, laneway, vertical lifting type and easy lift eight kinds, including lifting and transferring class of its simple structure, convenient operation, safe and reliable, and low cost in the domestic market share of 83% of the garage of the market share. Programmable controller (PLC) set of computer technology, automation technology, communications technology as a whole, reliable, cost-effective, compact
