摘要： A system for braking rotational movement of at least one beam is disclosed. The system can comprise a frame and at least one beam rotatably supported on the frame. Each beam of the at least one beam can comprise at least one sheave groove on at least one longitudinal end. A rope can have a first end and a second end. Each of the first end and second end can be fixedly coupled to the frame. The rope can be received within a portion of at least one of the at least one sheave groove of each beam. A tensioning assembly can be configured to selectively cause a predetermined braking tension in the rope.
