ESCALATOR CALIPER BRAKE ASSEMBLY WITH ADJUSTABLE BRAKING TORQUE

An escalator is provided with a caliper disc brake (2) for stopping movement of the steps in cases of emergency. The disc (4) is mounted on the main drive sprocket shaft (6), and the caliper (16) is normally held away from the disc (4). When power is removed from the drive, the caliper (16) is set o...

Zusammenfassung:	An escalator is provided with a caliper disc brake (2) for stopping movement of the steps in cases of emergency. The disc (4) is mounted on the main drive sprocket shaft (6), and the caliper (16) is normally held away from the disc (4). When power is removed from the drive, the caliper (16) is set on the disc (4) to stop further movement of the steps. The braking torque of the brake assembly (2) is adjustable to allow use of one basic assembly with escalators having different rises. The adjustment is accomplished by moving the center of gravity of the brake pads toward or away from the pivot axis (D) of the brake lever. The brake can also be finely tuned at installation to provide an optimum stopping distance and time so that a too abrupt stop is avoided.
