Don’t panic. Take a few deep breaths, and remind yourself that there’s plenty of oxygen in the elevator. Then do whatever makes you feel comfortable - hum your favorite tunes, do stretching exercises, read any book or magazine you may have with you.

In a typical elevator, the car is raised and lowered by three to eight motor-driven wire ropes that are attached to the top of the car at one end, travel around a pair of sheaves, and are again attached to a counterweight at the other end. The counterweight adds accelerating force when the elevator car is ascending and provides a retarding effort when the car is descending so that less motor horsepower is required. The counterweight is a collection of metal weights that is equal to the weight of the car & containing about 50% of its rated load. A set of chains are looped from the bottom of the Read the rest of this entry »
