A pulley system includes a cord and a pair of stages coupled at a pivot point, the stages being independently rotatable about a stage axis. A first pulley is attached to the stages at the pivot point. Two additional pulleys are attached to one of the stages. Braking elements are attached to one of the stages and engage the cord when an uneven tension is applied.
