ABSTRACT:
The emergency brake for a passenger conveyor such as an escalator or moving walkway is provided with a brake force adjustment assembly which will supply a braking force that is proportional to the passenger load imposed on the main drive motor of the conveyor at any point in time. Thus, if the conveyor is lightly or heavily loaded with passengers, the emergency brake force will be automatically proportionally decreased or increased so that, in the event of an emergency stop condition, the braking force applied to the drive sprocket axle will be sufficient to stop movement of the conveyor within the predetermined time period that is preprogrammed into the conveyor controller.
