Characteristics of equipment： 

①Building foundation pit can increase parking space，single combination space increased 0.6 times；
②The cross beam design can increase parking size，vehicle access is convenient；
③The motor+chain or wire rope drive，smooth operation，low noise；
④PLC programming control，simple operation；
⑤Has the advantages of simple structure，good stability，convenient maintenance。Solve the second floor surface and underground layer of the pillar skeleton structure，not only ensure second lift stability，and safeguard the underground layer of parking functioning。
⑥The flexible and modular design against different site condition will enable the installation of this device fast。
⑦Optimize the falling protector，which decrease the cost and increase the reliability of the falling protector。

Technical description：

①Equipment pillar position must be armoured concrete structure to fix the expansion bolt；
②The depth of the pit should be 2250mm，the net height size should be no less than 3600mm；
③The ground must be leveled，the level difference should be within ±5mm ；
④The location of device should be equipped with enough power supply；
⑤Put rain shield if device is laid at the open-air ground。

Working principle：

This type of parking system is designed 3 levels，top、middle and bottom。Two levels are on and above the ground ，the bottom level is underground，and every parking place is equipped loading pallet。There is an exchange space in the middle level，the spaces in top and bottom levels may lift up and down automatically and the spaces in the middle level can slide left and right。Spaces in the middle level are in the same line with the ground for cars going in and out freely。All of the steel pallets of top and bottom layer only can be lifted vertically to middle layer for parking or retrieving。This type of equipment increase a parking space than the type of Lift-sliding three layers on the ground。
