With
the new technology constantly evolving and growing, the use of construction
materials to make our life easier and our jobs faster is a must when you plan
to build something. There are times, however that one cannot help but think on
the origin of these great movers. Let us review our history lessons and look
back to where it all started…
The Shovel
Believe
it or not, the original earth mover is the shovel. In Neolithic times and
earlier a large animal's scapula (shoulder blade) was often used as a crude
shovel.
Manual
shoveling (often in combination with picking) was the chief means of excavation
in construction until mechanization via steam shovels and later hydraulic
equipment (excavators such as backhoes and loaders) gradually replaced most
manual shoveling. The same is also true of the history of mining and quarrying
and of bulk materials handling in industries such as steelmaking and
stevedoring.
Railroad
cars and cargo holds containing ore, coal, gravel, sand, or grains were often
loaded and unloaded this way.
Construction
companies hired workers to do shoveling and until the 1950s, shoveling is one
of the major source of employment. Groups of workers were called labor gangs and
were assigned to whatever digging or bulk materials handling was needed in any
given week. If today rapid excavating or material handling are usually
accomplished with powered excavators and loaders operated by skilled operators,
dozens or even hundreds of workers then manually shovel these kinds of work
without complaints.
Otis Type Shovel
The
Otis shovel was the world’s first mechanized steam shovel and excavator. In 1835, seeing the difficulty of shoveling
dirt and lifting heavy materials day in and day out, William Otis introduced
one of the most groundbreaking pieces of equipment to appear in the
construction and mining industry.
The
invention came about when Otis, employed by the firm Carmichael &
Fairbanks, was working on a contracting position involved in building the
American railroad. Working with strict time constraints, the firm would receive
bonuses if it could finish the work before assigned deadlines. The excavation
process and poor digging tools were delaying the project’s completion. This
gave Otis the incentive to seek out a solution, as the current practices used
for digging were very arduous and time-consuming. The traditional wagon-mounted
graders and horse-drawn dragpans were not efficient enough, thus, the invention
of the otis-type shovel.
This started the
evolution of machineries used in construction and mining and opened
possibilities for faster and more convenient way to deal with things.
In
April 1931, Caterpillar introduced its all-new "Auto Patrol"
rubber-wheeled grader. Late that same year, the Auto Patrol was renamed as the
No. 9 Auto Patrol. This machine formed the basis for all motor graders produced
by the earth-moving industry.
Thanks
to these equipment, construction companies such as Axis Capital Group based on
Singapore can now expand its business within a few years to other foreign
countries to make life easier for people who needs of it. Axis now has branched
out to Jakarta, Indonesia and has made it easier with the continuous production
of great earth movers that greatly contributed to the development of the
construction industry all over the world.
