<P>PROBLEM TO BE SOLVED: To mount a manually hoisting handle whose structure is rather simple on the motor of the hoisting machine. <P>SOLUTION: The hoisting machine of an elevator 100 is configured by the motor 110, a brake 120, and a sheave 130. A bearing hole 119 is formed in a bracket 113a of the motor 110, and a gear wheel 118 is fixed to a rotary shaft 114. If a handle shaft 151 of the manually hoisting handle 150 is inserted into the bearing hole 119, since a pinion 153 of the manually hoisting handle 150 is engaged with the gear wheel 118 on the motor side, a handle part 152 is manually rotated to allow the rotary shaft 114 and sheave 130 to be rotated, thereby enabling a car of the elevator manually. <P>COPYRIGHT: (C)2012,JPO&INPIT |
