Elevator Action
I thank Science for the gift of a reliable friend who lifts me
up and escorts me down with just one button push. Elevators take
people, as well as their baggages to wherever it is programmed
to go.
Elevators are enclosure or platforms that are operated by
cables, motors and other equipment or accessories enabling the
vertical shaft to go up and down, and transport people, freight
or both.
Elevators have a movable surface which takes full control of the
horizontal stabilizer that produces the upward and downward
motion.
Elevators have not only been helpful to people, but also to
business and industries which thrives mainly on the freight
services, the vertical transportation in mines, buildings, and
as well as in large ships.
Elevators are also used to carry equipments and machineries that
have belts or chains attached to buckets for the easy and
convenient transporting of bulk materials.
Elevator Discography
In the ancient times, elevators had buckets attached to the
conveyor that is used in simple hoisting of materials. Steam
operated elevators are used to convey materials in warehouses,
mines and factories back in the 19th century.
But during the time of the American inventor Elisha G. Otis in
year 1853, safety devices were produced to support and prevent
cables from breaking or falling off. In 1856, due to the burning
desire to improve the quality of technology that will be of a
great help in the industry,
Otis put up a manufacturing company where steam elevators are
patented. And shortly, after 5 years, during the time of
invention of Sir William Artstrong's hydraulic cranes, steam
powered elevators are slowly replaced by hydraulic machines.
From then on, hydraulic elevators were widely used in the
business industry as it is supported by a heavy piston,
gradually making motion inside a cylinder and is powered by
water or oil pressure which one produced by pumps.
After years of expertise, people have developed the new
generation of electric elevator which are operated by electric
motors - successfully leading to the truth birth of semi and
fully automated elevators. Now, modern elevators are proven to
speed up the quality of work, and its design.
Elevator codes and construction
In US and Canadian jurisdictions, standard model codes for
elevator construction is required in compliance with the
American Society of Mechanical Engineers. This is said to answer
forth all the inspection of elevators, security and maintenance,
as well as the elevator installation.
For safety measures, elevators are built under the strict
supervision of the Building Codes, and are expected to comply
with the standards and requirements stated by local authorities
having jurisdiction.
The an elevator lasts to up to more than 30 years. They are sold
in packages that are withheld as non-proprietary, and usually
comes with microprocessor controls.
Purchases with non-proprietory systems embarks a higher cost and
face value on the elevator, but letting buyers or owners take
over that responsibility or ownership may lower and even off-set
the elevator's long term cost.
Over the years, people continue to develop the quality and
abilities of such elevators.
Today, the most widely used elevators in all known business
field and industries are powered by microprocessors and are
fully controlled by computer generated devices, thus making the
elevator system run as smooth as it can in the roughest times of
the operation.
This task is referred to as the "traffic studies." Where
elevator experts and consultants uses a high-tech device to
control and allows access to different floors. Access to
elevators are successfully aimed through the use of access
codes, keys and card readers.
Elevator Safety
1. To maintain the quality of elevators, and to ensure that it
is on a good working condition all the time, seek for regular
schedule of renovation. The need to replace doors, interior cab
finishes, hoist machine, hoistway, car doors, floor landing
doors, hall fixtures, hydraulic pistons, and so on may arise.
2. Moreso, an additional code compliance states that renovation
and other related issues shall be reviewed with a professional
elevator consultant when it comes to buying new materials.
3. Elevators are the safest vehicle system the world has ever
known. However, in 1972, it has been reported that hydraulic
elevators tend to show possible events of danger, as there may
be a risk in hydraulic oil leak.
Whatever machine or equipment you use for whatever purpose they
serve, machine are like people who needs to visit their doctor
to monitor their body operations and functions.
Regardless of what type of gadget you use, science continue to
discover and improved high-tech equipments to improve the
quality of life, and not to put them in great risk.
