Abstract
A protective device for an elevator system extends about a rope and extends upward from an elevator car. The protective device blocks contact with the portion of the rope enclosed by the device. As a result, the risk of damage to the ropes caused by a person, such as a mechanic, who is present on the top of the car, is minimized. The invention is particularly advantageous for synthetic ropes that are subject to damage due to contact with abrasive objects or solvents. In one embodiment, the protective device is a tubular structure formed from a rigid, abrasion resistant material. In other embodiments, the protective device is a sheath formed from an abrasion resistant, woven fiber material that extends about the rope.
