ROBUST STARTUP METHOD FOR ROPELESS ELEVATOR |
| 摘要 |
A method of startup from a resting state for a ropeless elevator system and a ropeless elevator system are disclosed. The ropeless elevator system may include a hoistway. The method for startup may include applying a thrust force on the brake, the thrust force generated by a propulsion system, detecting the thrust force on the brake, determining if the thrust force on the brake is greater than or equal to a requisite thrust force for startup, and disengaging the brake if the thrust force on the brake is greater than or equal to the requisite thrust force. |

1. A method for startup of an elevator car (24) in a ropeless elevator system (20), the ropeless elevator system (20) including a hoistway (22), the method comprising:
applying a thrust force on the brake (76), the thrust force generated by a propulsion system (50); detecting the thrust force on the brake (76); determining if the thrust force on the brake (76) is greater than or equal to a requisite thrust force for startup; disengaging the brake (76) if the thrust force on the brake (76) is greater than or equal to the requisite thrust force. |
