Elevator system

Abstract

The invention relates to an elevator system in tall buildings, said system comprising at least one first elevator shaft (13), which houses an elevator arranged to stop at floors called transfer levels (8, 8a), and at least one second elevator shaft (14), which houses elevators whose elevator cars (22) are disposed one above the other in the elevator shaft, which elevator cars are designed to stop during their travel at any floor to which or from which a call has been issued. The second elevator shaft (14) is divided vertically into local shafts (17, 18, 19) situated one above the other, the number of which is at least one for each zone between transfer levels (8, 8a).

Description

technical field [0001] The present invention relates to an elevator system, in particular to an elevator system for a high-rise building in which passengers wishing to reach the upper floors have to take an elevator which primarily serves only the upper floors. Background technique [0002] In very tall buildings it is generally not economical to provide a shaft extending the entire height from the ground floor to the top floor so that each elevator serves all floors. For this reason, elevators are usually divided into different areas in the vertical direction, wherein the lowest area extends from the entrance floor, that is, the ground floor, to a designated level, which is called the low floor area, and the upper area, called the upper floor area, extends from the so-called high floor area. The designated transfer level at the upper porch level extends to the topmost level of the building. Between these zones, depending on the height of the building, there may be one or m...

Problems solved by technology

The problem here is also the risk of collision, since there is always the possibility that if the program malfunctions or an error occurs, two cars moving towards each other in the same shaft will collide
