Elevator design by the German engineer Konrad Kyeser (1405). The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes (c. 287 BC – c. 212 BC) built his first elevator probably in 236 BC. [2]

The restraining bar is useful for children—who do not fit comfortably into adult sized chairs—as well as apprehensive passengers, and for those who are disinclined or unable to sit still. In addition, restraining bars with footrests reduce muscle fatigue from supporting the weight of a snowboard or skis, especially during long lift rides.
Pushback tugs can also be used to pull aircraft in various situations, such as to a hangar. Different size tugs are required for different size aircraft. Some tugs use a tow-bar as a connection between the tug and the aircraft, while other tugs lift the nose gear off the ground to make it easier to tow or push.
The first T-bar lift in the United States was installed in 1940 at the Pico Mountain ski area. [14] It was considered a great improvement over the rope tow. An earlier T-bar was installed at Rib Mountain (now Granite Peak Ski Area), Wisconsin, in 1937. In recent years, J-bars are no longer used in most ski areas.
A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 992 lbs.) [2] Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys.
