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 ...
A home lift not to be confused with a home elevator is a type of lift specifically designed for private homes, where the design takes into consideration the following four factors: 1. Compact design in view of the limitations of space in a private residence, 2. Usage of the lift restricted primarily to the residents of the private homes, 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.

The secondary drive connects with the drive shaft before the gear box, usually with a chain coupling. Some chairlifts are also equipped with an auxiliary drive, to be used to continue regular operation in the event of a problem with the prime mover. Some lifts even have a hydrostatic coupling so the driveshaft of a snowcat can drive the chairlift.
The total weight of the barbell varies based on the type and number of plates loaded onto the ends of the bar and the lift being performed, and easily can be 540 kilograms (1,190 lb) or more with a squat dedicated bar (which itself can weigh up to 29 kg (65 lb) and have up to 35 mm (1.4 in) grip section diameter).
There are six lift shafts of varying heights and speeds, including a high-speed shaft with a travel of 100 metres (328 ft 1 in) and a theoretical maximum speed of 10 m/s (33 ft/s). The tower's renovation was officially completed in July 2010. [ 5 ]
