Abstract:
To provide a ball hoisting device which can prevent the driving of a drive motor under improper situations.
This ball hoisting device 1 has a system operation switch 80b for directing the driving of the drive motor 4 and a guide rail closure sensor 53 which detects whether or not a guide rail 20 is closed, and when the guide rail closure sensor 53 does not detect the closure of the guide rail 20, the operation of the system operation switch 80b can be canceled.
