In the case of office buildings, the importance of vertical transport lines has been increasing as many new office buildings have recently become more and more high and large. The establishment of an efficient transport system is now a must, in order to accurately manage office documents of increased complexity and an enormous amount of materials including mail matters. S&S Engineering’s in-house transport systems have contributed a lot in such applications as the book lending and returning to and from users in a library, the in-house mail services for exchanging documents which cannot be computerized in business firms, financial institutions (securities firms), government and other public offices, etc., and the recycling for unnecessary documents through separation and collection of wastes.
