Abstract (en)
[origin: EP3363759A1] An elevator device having a novel governor device to infallibly realize meshing between ratchet teeth of a ratchet wheel and a pawl of a fly weight is provided. To fly away a fly weight (18A), with a weight support shaft (27A) to rotatably support the fly weight (18A) as a border, a pawl(28) meshed with ratchet teeth (17) of a ratchet wheel (16) is attached to one side of the fly weight (18A). An inertia mass adjusting unit (33A) to adjust the inertia mass of the fly weight to that equivalent to or smaller than the inertia mass of the ratchet wheel (16) is formed on other side of the fly weight (18A). With this configuration, it is possible to infallibly realize meshing between the ratchet teeth (17) of the ratchet wheel (16) and the pawl (28) of the fly weight (18A), and eliminate adverse effects such as delay of the operation of an emergency stop device.
