Beam climber brake condition-based monitoring system

Abstract

A system for detecting a dragging brake of an elevator system including: an elevator car configured to travel through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam including a first surface and a second surface opposite the first surface; a beam climber system configured to move the elevator car through the elevator shaft, the beam climber system including: a first wheel in contact with the first surface; and a first electric motor configured to rotate the first wheel; at least one brake configured to slow the elevator car to a stop; and a brake condition based monitoring system configured to determine a brake health of the at least one brake.
