the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
Headframe of the #1 Shaft at Oyuu Tolgoi. A steel headframe is less expensive than a concrete headframe; the tallest steel headframe measures 87 m. [4] Steel headframes are more adaptable to modifications (making any construction errors easier to remedy), and are considerably lighter, requiring less substantial foundations.

At 2,500 pounds (1.1 t), the 9N could plow more than 12 acres (4.9 hectares) in a normal day pulling two 14-inch (360 mm) plows, [3] outperforming the tractive performance of the heavier and more expensive Farmall F-30 model. [3]
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. [1]
