ABSTRACT:
The present invention provides a carrier stopping device for a conveyor having a disengageable propelling member, such as a power and free conveyor. The stopping device preferably utilizes a linear induction motor to activate a stop plate of the stopping device. The stop plate is locked in an extended position and a retracted position by a locking pin which reacts to the electromagnetic force of the linear induction motor.
