The section lift coefficient is based on two-dimensional flow over a wing of infinite span and non-varying cross-section so the lift is independent of spanwise effects and is defined in terms of ′, the lift force per unit span of the wing. The definition becomes
A hydraulic cantilever tail lift on the back of a truck Four stages of deployment on an ambulance tail lift Control for a tail lift. A tail lift (term used in the UK, also called a "liftgate" in North America) is a mechanical device permanently installed on the rear of a work truck, van, or lorry, and is designed to facilitate the handling of goods from ground level or a loading dock to the ...
The truck can pick up significantly heavier objects compared to the human and move it to a new location. Since the forks can be adjusted, the height of the lift can also be adjusted so that employees can lift in a more neutral position. The use of forklifts can eliminate or reduce some exposures of manual material handling.
In 1959 Ron Aguirre of Rialto California installed hydraulics in his custom 1956 corvette the X Sonic and shortly thereafter, Aguirre began installing Hydraulic lifts in many custom cars in the Inland Empire. During the early 1960’s front hydraulic lifts became a very popular upgrade in many semi custom cars in California.
A forklift (also called industrial truck, lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark , which made transmissions , and Yale & Towne ...
Lift is always accompanied by a drag force, which is the component of the surface force parallel to the flow direction. Lift is mostly associated with the wings of fixed-wing aircraft , although it is more widely generated by many other streamlined bodies such as propellers , kites , helicopter rotors , racing car wings , maritime sails , wind ...
F is downforce (SI unit: newtons) C L is the lift coefficient; ρ is air density (SI unit: kg/m 3) v is velocity (SI unit: m/s) A is the area of the wing (SI unit: meters squared), which depends on its wingspan and chord if using top wing area basis for C L, or the wingspan and thickness of the wing if using frontal area basis
