sub title : Super-High Level Is Possible by Multistage Hydraulic Cylinder to 88m
issue : 3. 2003

No waday, it is possible to park huge vehicles like ultra truck, express bus in the automatic parking system. EZ INDUS Co.(President Jun woo gon, www.ezindus.com), a professional company in developing ways of carrying load, developed super-high level hydraulic lift parking system for heavy truck 'UTP(Ultra Truck Parking system)' by utilizing hydraulic multistage cylinder leveling method and wait for market launching. Herewith lessen the parking area problem of heavy vehicle entangle with government policy of extending public parking places.
CEO Kim noticed that warehouse and parking system have a same mechanism and invested 3 billion won for 5 years, completed development last May.2002. Now it's under patent pending in 100 countries. Hereafter form a consortium with KDN(Korea electricpower Data Network) and world-wide plant company M＋W zander, plan to collaboratively receive orders and carry out construction works.
The charateristic of this system is a special designed multistage hydraulic cylinder which make it possible to park 30 full loaded(10 tons) heavy trucks in 150 square meter. Due to legal in and out time defined by 'Law on Parking Places' changed 2 and a half hour to 2 hour at last May 29, the height is limitted 15 stages or 88m. EZ INDUS Co. broke through speed and height limitation of hydraulic method by adopting linked multiple cylinders move like single cylinder, servo type hydraulic system automatically control flow rate and pressure precisely. Capacity of the electricmotor is 90 Kw, output of power of hydraulic motor is 150 Kw, rampant motor is 5 Kw and average in and out rate of car is 3 and a half minutes. Unit size is 10,000mm width × 15,000mm length × 120,000mm height and pallet size is 2,700mm width × 12,000mm length × 5,500mm height.
Compare EZ INDUS Co.'s UTP system and other companies' rope type parking system, UTP system have merits as follows, main drives such as hydraulic motors and cylinders located in ground of system put a lowest load on iron frames, high resistive on side pressure by strong winds and low operating vibration. Also, rope type parking system have many consumable parts and high deformation rate of rope but UTP system have a few consumable parts and high durability due to hydraulic characteristics.
Now, UTP system is engaged in business, but it is hard to fix or realize because government offices don't want to bear risk of 'the very first case'. On account of the first in domestic production, no regulations for heavy truck and buse automatic parking systems are registered in 'Law on parking'. EZ INDUS Co. have plan to reinforce business and positive advertisement toward government offices all around this year.
