Hitachi unveils elevator cars that circulate in loop+


(Japan Economic Newswire Via Thomson Dialog NewsEdge)TOKYO, March 1_(Kyodo) _ Hitachi Ltd. said Wednesday it has developed a new elevator system in which more than two cars can run, sharing the space conventionally used by two.

In the new system, each car moves sideways after reaching the top floor and then descends before shifting sideways again at the bottom to move up as each car is attached to a single cable loop, Hitachi officials said.

The system can save considerable space, reduce passenger waiting time and transport more than double the number of people compared to conventional elevators, the company said.

The Japanese machinery maker hopes soon to market a system with six to eight cars for use in 10- to 20-story office buildings after obtaining official safety approval.

Unlike large, rapid elevators used in high-rise buildings that skip many floors, the new system is suited for making a stop at each floor.

Hitachi says it has conducted successful trial runs on a prototype system about one-tenth the size of a system for actual use.
