A double-deck elevator or double-deck lift is an elevator where one cab is stacked on top of another. This allows passengers on two consecutive floors to be able to use the elevator simultaneously, significantly increasing the passenger capacity of an elevator shaft.
A passenger elevator is designed to move people between a building's floors. Passenger elevators capacity is related to the available floor space. Generally passenger elevators in buildings of eight floors or fewer are hydraulic or electric, which can reach speeds up to 1 m/s (200 ft/min) hydraulic and up to 3 m/s (500 ft/min) electric.
They show an almost linear increase in lift coefficient with increasing angle of attack with a gradient known as the lift slope. For a thin airfoil of any shape the lift slope is π 2 /90 ≃ 0.11 per degree. At higher angles a maximum point is reached, after which the lift coefficient reduces.
For example, if the dimensions are all doubled in size, then the area and lifting capacity increase 2 × 2 = 4 times, while the volume increases 2 × 2 × 2 = 8 times. For a passenger aircraft, this doubling in size allows up to twice the cabin space per passenger.
A freight rate (historically and in ship chartering simply freight [1]) is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport (truck, ship, train, aircraft), the weight of the cargo, and the distance to the delivery destination.
There is also a gauge for locomotives. The size of container that can be conveyed depends both upon the size of the load that can be conveyed and the design of the rolling stock. [18] W6A: Available over the majority of the British rail network. [19] W8: Allows standard 2.6 m (8 ft 6 in) high shipping containers to be carried on standard wagons ...
The most common and noted type of containers are the 20 feet and 40 feet containers. There are also containers with an extent in height called "High Cube" containers. [3] [9] The fixed exterior dimension of the standard size boxes are: [9] [10] 20 feet container size is: 20 ft (6.1 m) length by 8 ft (2.4 m) width by 8.6 ft (2.6 m) height.
The Freightos International Freight Index was first launched as a weekly freight index in early 2017. [7] The Freightos Baltic Index has been in wide use since 2018. [8] It is currently the only freight rate index that is issued daily, and is also the only IOSCO-compliant freight index that is currently regulated by the EU (in particular, the European Securities and Markets Authority).
