  • Patent number: 4226187
    Abstract: The safety equipment is used in conjunction with a conventional ski lift system having a series of towers plus turnaround stations, arms extending out from the towers, and single or multiple bogey beams, each having at least two rope support sheaves. A continuous cable, or rope, extends over all of the support sheaves and around the end stations. The safety features include a secondary sheave mounted beside and outward of the primary sheaves with its upper margin below the upper margins of the primary sheaves. If a rope is displaced from the primary sheaves it will fall into the groove on the secondary sheave. To prevent displacement from the secondary sheave, a star wheel is mounted above the sheaves for rotation on a horizontal axis and the radial fingers pass down close to the outside of the secondary sheave and overlap its upper portion. The gap between the sheave and the guard fingers is so small that a rope cannot fall between them.
