Title:
ELEVATOR EQUIPMENT
Document Type and Number:
Japanese Patent JP2013119458
Kind Code:
A
Abstract:

To provide elevator equipment capable of obtaining an elevator car position adjusting means with a short adjustment stroke.

The elevator equipment includes a sliding body position detector 11 which detects a position at which a sliding body 7a is located, the position of an adjustment stroke possessed by an elevator car position adjusting means 7, a load measurement means 12 for measuring a movable load of an elevator car 2, and a control means for adjusting in advance a position of the sliding body by determining a range of an increase/decrease in a movable load on a next target floor on the basis of the movable load on a landing floor 6. Before an elevator car moves to the next target floor after correcting a level displacement, the movable load of the elevator car is measured, an increase/decrease range in the movable load, for example, by the load/unload of a passenger on the next target floor is determined, and a level displacement amount due to an increase/decrease in the movable load is calculated. On the basis of the result of this calculation, before the elevator car reaches the target floor, a sliding body is moved in advance to a position where a predicted level displacement can be corrected.
