Abstract

The invention provides an elevator, which is easily provided with a balance weighting which is movable, and can easily perform maintenance of a balance weighting movable mechanism. The elevator (1) includes a car (120), the balance weighting (13), a balance weighting movable mechanism (13), and a control part (11). The balance weighting (13) can move on the side of the car (120), and the balance weighting movable mechanism (13) is disposed on the upper part of the car (120) and supports movably the balance weighting (13). The control part (11) controls the balance weighting movable mechanism (13) according to the position of the car (120) in a lifting channel.

Description

technical field The present invention relates to an elevator for raising and lowering and transporting people and goods in a lifting passage arranged in a building structure. Background technique In general, in a rope-rope elevator, a balance counterweight is provided in the car in order to correct the inclination of the car. However, suspension members such as tail ropes connecting the car and the control unit, compensating ropes for adjusting the tension of the main ropes, and the like are connected to the lower part of the car. Then, suspension members such as tail ropes and compensating ropes hang down from the car toward the bottom of the lifting direction. When the car moves up and down, the length of the suspension member suspended from the car changes, so the load applied to the car 320 from the suspension member also changes. As a result, the change in the load on the suspension member due to the vertical movement of the car cannot be eliminated, and there is a p...
