Aerial lifts have a variety of mechanisms to ensure safe operation over a lifetime often measured in decades. In June 1990, Winter Park Resort performed planned destructive safety testing on "Eskimo", a 1963 Riblet Tramway Company two-chair, center-pole fixed grip lift, as it was slated for removal and replacement with a high-speed quad Poma lift. The destructive testing attempted to mimic potential real-life operating scenarios, including tests for braking, rollback, oily rope, tree on line, fire, and tower pull. The data gleaned from this destructive safety testing helped improve the safety and construction of both existing as well as the next generation of chairlifts.
