Problems solved by technology

However, when the hand-wound device is forgotten to be removed and the motor is directly energized to rotate it, protrusions such as the handle of the hand-wound device will rotate, causing workers to fall into a dangerous situation
Also, even in the event that the handle falls off due to this rotation, it is dangerous for workers
[0006] However, in the past, there was no safety unit for forgetting to disassemble the hand-wound device.

Abstract

The present invention relate to a passenger conveying machine such as an escalator or a moving sidewalk. The passenger conveying machine can not run when a hand winding apparatus is forgotten to dismantle. The hand winding apparatus is provided with a barrel-shaped shaft section (44) engaged with a rotation shaft (34) of a motor (20), a handle (50) disposed at the shaft section (44), a limit switch (54) disposed at the shaft section (44) and working when engaged with the rotation shaft (34), and a cable (62) connected with the limit switch (54) and extending from the shaft section (44).

Description

[0001] References to related applications such as the priority basic application: [0002] This application is based on Japanese Patent Application No. 2011-133426 (filing date: June 15, 2011), and enjoys the priority benefits of this application. This application incorporates the entire content of the same application by referring to these applications. technical field [0003] Embodiments of the present invention relate to passenger conveyors such as escalators and moving walkways. Background technique [0004] In the past hand winding device, when the installation operation or inspection operation of the passenger conveyor, when the step chain is not energized, the staff installs the handle on the rotating shaft of the motor or reducer, and rotates the handle manually. This rotates the steps and thus the chain of steps. [0005] In the hand-wound device as described above, the hand-wound device is detached from the motor or the like after the installation work or the in...
