Abstract
An elevator installation has a first cage pair a second cage pair, both movable in an elevator shaft. Cages of a cage pair can move simultaneously in opposite directions within the shaft. In the shaft is a change zone which allows the cages of the cage pair to change between sides of the shaft while in upward or downward motion.
Claims20
An elevator operation method, comprising:
- in an elevator shaft in which are disposed first and second elevator cage pairs, moving a first elevator cage of the first elevator cage pair downwardly along a first vertical side in the elevator shaft while moving a second elevator cage of the first elevator cage pair upwardly along a second vertical side in the elevator shaft, the first and second vertical sides including a change zone intermediate upper and lower ends of the first and second vertical sides;
- and
- while the first elevator cage of the first elevator cage pair is moving downwardly and the second elevator cage of the first elevator cage pair is moving upwardly, and after the first elevator cage of the first cage pair at least partially passes the second elevator cage of the first elevator cage pair in the change zone, moving the first elevator cage of the first cage pair from the first vertical side of the elevator shaft to the second vertical side of the elevator shaft and moving the second elevator cage of the first elevator cage pair from the second vertical side of the elevator shaft to the first vertical side of the elevator shaft.
An elevator installation comprising:
- a first pair of elevator cages disposed in a shaft, the shaft comprising first and second sides and a change zone, the change zone being positioned between upper and lower floors served by the elevator installation ;
- and
- a second pair of elevator cages disposed in the shaft, wherein the first elevator cage of the first pair is configured to move downward along the first side while the second elevator cage of the first pair moves upward along the second side, the first and second elevator cages of the first pair being configured to move between the first and second sides of the shaft in the change zone.
An elevator control system comprising:
- a first elevator drive control;
- and
- a second elevator drive control, wherein the first elevator drive control is configured to instruct a first elevator drive in an elevator installation and the second elevator drive control is configured to instruct a second elevator drive in the elevator installation, wherein the first and second elevator drive controls are further configured to coordinate the movement of two pairs of elevator cages within an elevator shaft, the movement within the elevator shaft comprising upward movement, downward movement and movement between left and right sides of the elevator shaft in a chance zone positioned between upper and lower floors served by the elevator cages.
