Beam climber active brake health monitoring system

A method of detecting brake drag within an elevator system, the method comprising:

• rotating, using a first electric motor of a beam climber system, a first wheel, the first wheel being in contact with a first surface of a first guide beam that extends vertically through an elevator shaft;
• moving, using the beam climber system, an elevator car through the elevator shaft when the first wheel of the beam climber system rotates along the first surface of the first guide beam;
• detecting, using a brake condition based monitoring system, when a first motor brake is dragging;
• detecting a torque of the first electric motor, wherein the brake condition based monitoring system is configured to detect when the first motor brake is dragging based upon at least a torque of the first electric motor;
• normalizing the torque of the first electric motor based on the center of gravity of the elevator car.

A method of detecting brake drag within an elevator system, the method comprising:

• detecting a load within an elevator car;
• determining a center of gravity of the elevator car;
• determining a predicted motor torque of an electric motor of a beam climber assembly during a constant speed of the elevator car;
• adjusting a motor torque detection range for the electric motor based on the load within the elevator car and the center of gravity;
• moving the elevator car, using the beam climber system, for an elevator run and recording the motor torque experienced by the electric motor during a constant speed portion of the elevator run;
• detecting whether the motor torque experienced by the electric motor during the constant speed portion of the elevator run was outside of the motor torque detection range that was adjusted based on the load within the elevator car and the center of gravity;
• and
• activating an alert if the motor torque experienced by the electric motor during the constant speed portion of the elevator run was outside of the motor torque detection range that was adjusted based on the load within the elevator car and the center of gravity.
