Problems solved by technology

[0004] However, in this elevator device, because the car chamber wall is provided with a maintenance door, the design of the car chamber is reduced.
In addition, only the equipment opposite to the maintenance door can be operated, and the working range is narrow
In order to work on multiple devices arranged in different locations, it is necessary to install multiple maintenance doors, which further reduces the designability
In addition, if equipment is installed near the uppermost part of the elevator shaft, maintenance doors must be installed on the upper part of the car chamber wall, and additional places for feet, etc., must be provided.

Embodiment 1

[0015] Fig. 1 is a perspective view showing an elevator apparatus according to Embodiment 1 of the present invention, and Fig. 2 is a perspective view showing a state of the elevator apparatus of Fig. 1 during maintenance work.

[0016] In the figure, a pair of car guide rails 2 and a pair of counterweight guide rails 3 are arranged in the hoistway 1 . The car 4 is guided by the car guide rail 2 to move up and down in the hoistway 1 . The counterweight 5 is guided by the counterweight guide rail 3 to move up and down in the elevator shaft 1 .

[0017] A support member 6 is fixed to an upper end portion of the weight guide rail 3 . A driving device (hoist) 7 for raising and lowering the car 4 and the counterweight 5 is supported on the supporting member 6 . The drive device 7 has a drive device body 8 including a motor, and a drive sheave 9 driven to rotate by the drive device body 8 .

[0018] A plurality of main ropes 10 are wound around the driving sheave 9 . The car 4 a...

Abstract

An elevator device involves a cage, which consists a body, an entrance, and a ceiling. The ceiling is located between theo opening part, which is arranged above the cage, and the passenger space. It can be controlled to move up and down by the switches in the sidewall of the passenger space.

Description

technical field [0001] The present invention relates to an elevator device for performing maintenance work on equipment installed in an elevator shaft from a car. Background technique [0002] In a conventional elevator system in which equipment is installed on the upper part of the elevator shaft, the operator climbs on the upper side of the car to perform maintenance work. Like this, in the upper part in the elevator shaft, it is necessary to ensure a space for maintenance work, and this space correspondingly increases the upper gap size (suspension size) of the elevator shaft. That is, the space for work on the car hinders the space-saving of the entire elevator apparatus. [0003] In the traditional elevator device disclosed in Japanese Patent Application Laid-Open No. 2000-106459, a maintenance door is provided on the wall of the car chamber. When the maintenance door is opened, the equipment in the hoistway can be repaired and maintained from the car chamber. [0004...
