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. |
