德国蒂森克虏伯集团宣布,在世界上首次开发出了不使用钢缆的电梯系统。该电梯采用线性马达作为动力,可以在上下和水平方向上移动。通过应用该电梯,将提高大楼等设计的自由度,且运载能力也可以提高50%。新开发的电梯系统被称为MULTI。该系统采用的是让载人轿厢在被称为井道的空间内自动移动的机制。由于可上下左右移动,因此能够建造环状轨道,以同时 ThyssenKrupp AG announced that it has developed for the first time in the world an elevator system that does not use steel cables. The elevator uses a linear motor as a power, can move up and down and horizontal. By using the elevator, the design freedom of the building and the like will be increased, and the carrying capacity may be increased by 50%. The newly developed elevator system is called MULTI. The system uses a mechanism that allows the passenger car to move automatically in a space called the hoistway. Since it can be moved up, down, left and right, it is possible to construct a ring-shaped track for simultaneous use
