The loaders are heavily
used in the construction industry, generally for moving heavy
materials and loads from one location to another. These heavy
construction machines are included in various projects like leveling
and planning the ground site, road construction and infrastructure,
digging holes, trenches and etc. The loaders are specially designed
to be capable to move different kinds of materials like wooden chips,
sand, debris, rocks, stones, concrete, recycled materials and many
other types of heavy loads. The history of this construction machine
can be traced back to 1920's when tractors equipped with buckets for
material handling were firstly manufactured. In 1953, Caterpillar
managed to develop a hydraulic loader, and after the WWII this
hydraulic loader became fully commercialized machine. Since then, the
loader is present at every construction site capable to perform and
to complete different kinds of construction tasks. Today different
loader models can be found on the market with different names like:
wheel loader, crawler loader, track loaders, front end loader,
backhoe loader and etc. The most commonly used are described bellow.
Types
of Loaders:
Wheeled Loader
The
wheeled loader comes with a metal bucket attached at the front end of
the machine. This type is used for lifting loose materials from the
ground like sand, dirt, gravel, and to transfer these loose materials
from one location to another. Generally the wheeled loaders are used
for moving materials on the ground, to load and to unload them on
other construction vehicles like dump trucks. Thanks to their
maneuverability, these heavy machines are ideal for confined areas
and locations.
Crawler Loader
This particular loader comes with tracks instead of wheels. It
combines the features of the crawler tractor and the features of the
wheeled loader. The manufacturing process of the crawler loader
requires more than simply placing a metal bucket in front of the
crawler tractor. The crawler loader comes with hydrostatic
transmission and hydraulic controls for higher efficiency. The
hydraulic system increases the power of the machine, and as a result
of that the crawler loader can dig much harder on the ground.
The crawler loader is capable to complete various construction
tasks, and because of that it is a common machine at every
construction site.
Skid Steer Loader
This
construction machine is described as multi functional machinery,
designed to be used for different purposes. It can be found either as
a crawler skid steer or as a wheeled skid steer loader. The skid
steer loader can be used for completing different tasks by installing
various attachments. It can be quickly converted into a snow blower,
mower, loader or into a mini sized bulldozer. These machines are
heavily used in landscaping.
Backhoe Loader
This
machine is also known as digger or simply as a backhoe. It comes
equipped with one metal bucket at the front end and a small backhoe
at the rear end. Thanks to its relatively small compact size, the
backhoe loader is used in many small construction projects such as
construction of local and urban roads or construction of small
residential houses. Furthermore, the backhoe loaders are used for
breaking asphalt, paving roads, digging holes and trenches,
landscaping, excavation, demolitions and many other construction
tasks.
Loader Manufacturers
Today
different models of loaders can be found on the market, designed and
engineered by different world known manufacturers. The main loader
manufacturers in the world are: Caterpillar, John Deere, New Holland,
Volvo, Komatsu, Massey Ferguson, Mitsubishi and many others.
