Excavators-Heavy Machinery for Heavy
Construction!

Excavators are enormous industrial machines that
are used for a variety of tasks, such as
transporting bulky objects like boulders and
pipes and even deep digging, mining etc.
WHAT ARE EXCAVATORS
3
AN INNOVATIVE HISTORY
Excavators were first designed by two Italian
brothers, back in 1948. At first, the Excavators
were designed using Hydraulic technology during
the 1880s but in the case of hydraulic fluids
water was used and the machine buckets were
operated by cables. In India, it took a quite of
time to come into action but it started its
action during the 1960s and continues to evolve
with modern technologies till now.

TOP 5 DEFINING EXCAVATORS

• Crawler Excavators are mainly general excavators
  with two rotating tracks instead of wheels.
• Short Swing Radius Excavators are ideal for
  places that need to be as productive as possible
  while maintaining the sanctity of space.
• Wheeled Excavators are suitable for situations
  requiring a great deal of versatility, such as
  while building roads or installing utilities.
• Backhoe Excavators are typically employed on
  construction sites for small-scale digging or
  excavation as well as light hauling.
• Long Reach Excavators, are typically employed for
  harsh construction tasks, such as the demolition
  of structures.

GENERAL PARTS OF EXCAVATORS

• Boom- It is an important factor of an excavator
  since it functions as the main load-taking part
  it is an arm-like structure and a link between
  the machine and the ground.
• Arm- It has to adapt to various working
  environments and assists in guiding the boom.

GENERAL PARTS OF EXCAVATORS

• Bucket- It is primarily a huge claw-like
  attachment with a bucket-like shape that is
  attached to the excavator's arm and can support
  heavy weights when digging or for any other
  purposes.
• Undercarriage- All of the crucial elements that
  support the Excavator's general functionality are
  contained in this structure. It mostly
  communicates with the final drive hydraulic motor
  and hydraulic system.

USES OF EXCAVATORS

• Digging
• Handling of large materials
• Construction
• Maintenance
• Farming
• General Landscaping

10
ADVANTAGES OF EXCAVATORS

• They are easily operatable
• Handles every terrain
• Easily Transportable
• Cost Saving
• Easy to use
• Saves Time

11
DISADVANTAGES OF EXCAVATORS

• More expansible than the mechanical
• Maintenance costs are higher
• Makes Noise and Air Pollution
• Lots of heat are generated leading to a decrease
  in efficiency
• The Viscosity and oil temperature affect the
  internal working efficiency of parts
