What are the driving trends in the excavator equipment
in India?
Excavators have been in use in large and small scale constructions. Excavator technology is improving
on an almost daily basis. Whether it is asphalt compactors or soil compactors, the thrust from
manufacturers has been on machines that will achieve optimum compaction with the minimum
number of passes. The trend that has been witnessed in the Indian compaction market is the
movement towards vibratory compaction from the earlier predominantly static rollers. Manufacturers
are also incorporating more sophisticated hydraulic functions that allow the operator to adjust
hydraulic flow to the application. Manufacturers are also incorporating more sophisticated hydraulic
functions that allow the operator to adjust hydraulic flow to the application. In the light of road
projects and initiatives being declared by the government, the excavator market is foreseeing an
uprising demand.
Given below are a few of the key trends in the excavator market.
Excavator propelled by hydraulic power
Hydraulic excavators find applications in mining, infrastructure and other similar sectors. Modern
hydraulic excavators come in a wide range of sizes. The new hybrid models now manufactured has
the lowest ever fuel consumption and has also been designed to further reduce CO2 emissions and
running costs. Incorporating proven technology, an advanced hydraulic system and a new lightweight
arm, it achieves this without compromising on high levels of performance and easy operation. One of
the key benefits of hydraulic machinery is the ability to achieve motion via hydraulic actuators such
as cylinders and swing motors. Through the use of multiple actuators, extremely complex motions are
made possible. And with hydraulics providing the power behind these motions, machines like
excavators can dig deeply into the earth or front loaders can scoop, lift up, and deposit heavy loads of
soil or rock. And hydraulics, coupled with a skilled operator, can achieve motion to an amazing degree
of precision. Modern graders with hydraulic systems are capable of far greater accuracy than their
cable, winch, and linkage operated ancestors. And when hydraulics are combined with modern

technology such as grade control, laser positioning, and GPS, the potential seems almost endless. The
vast majority of equipment found on construction sites across the world is propelled by hydraulic
power. That includes hydraulic final drive motors that convert hydraulic power to torque to enable
track loaders, bulldozers, diggers, and backhoes to carry or push heavy loads. These motors, which
are sometimes referred to as track motors, enable tracked excavators, bulldozers, and other tracked
machines to keep moving across some of the most difficult surfaces imaginable. These hydraulic
propelled motors rely on the machine’s hydraulic system to function correctly.
Advanced hydraulics excavator technology
Hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the
advent of hydraulic-powered attachments such as a breaker, a grapple, or an auger, the excavator is
frequently used in many applications other than excavation. Many excavators feature a quick coupler
for simplified attachment mounting, increasing the machine’s utilization on the jobsite.
Manufacturers are also incorporating more sophisticated hydraulic functions that allow the operator to
adjust hydraulic flow to the application. Hydraulic upgrades on the latest models include selectable
modes to optimize available hydraulic speed and power, plus a manual throttle dial to adjust engine
speed and power as needed. Hydraulic efficiency has been a big concentration point for
manufacturers. Efficiency is a result of improved system designs that are capable of higher pressure,
increased cooling and optimized use of the available oil flow. The lower engine horsepower found in
some machines has also created a need to do more with less, making more efficient hydraulics a
requirement.
Excavator operational safety
Excavators should be equipped with adequate visibility aids to ensure drivers can see areas where
people may be at risk from the operation of the machine. An operator’s efficiency is paramount with
regard to optimising the output. Comfort and safety of an operator are of paramount importance as it
not only ensures safe operations at the construction site but also increases the efficiency of the
operator. Excavators are now provided with isolated operator platforms where there is no feeling of
vibration of the machine. This improves the stress-free operation of the machine & improves the
operator’s efficiency.
Excavators are now being built with the patented design of three-point pendulum articulated joints.
Operator efficiency is improved by the isolated operator platform, by providing comfortable seats
that will help operators to have better stability. A conveniently positioned control on the operational
panel is being attached now which allows easy switching of work modes, depending on working
conditions. The steering wheel and console are designed to ensure fatigue-free operation and The cab
platform is mounted on viscous mounts, to isolate it from any vibrations and to make the operator
feel comfortable even during high amplitude passes.
Operator-friendly language in excavators
Buyers have become more educated and demanding in terms of wanting machines suited to the kind
of work and environment that they work in. Customisations have to be in sync with the market and
the on-ground realities for making the most of it. A country like India where there is no unifying
language and different languages are spoken in every district and state, it becomes counterproductive
to have all instructions about the machine in a single language. This simple customisation helps
interact better with the operator. So customisation of voice recognition systems is mandatory in this
part. Not only in language, but simple software customisation also helps keep a log of the machine’s
data for future reference. It also helps keep track of the machine’s numbers in terms of efficiency and
fuel consumption. The customised software helps run troubleshooting and diagnostic measures to

ensure the safety and efficacy of the machines. The manufacturers are now customising machines as
per the need of a particular terrain.
Smart technology in excavator
There is an adaptation of control methodology in relation to accuracy, repeatability, and efficiency.
Manufacturers are using modified mechanisms and electrical sensors to ensure safety guidelines.
There is a definite shift towards the adoption of newer technologies for industries as well which can
be seen in specifically in the crane system modulation. The Internet of Things (IoT) is one of the
hottest topics in the construction sector and with good reason. It influences the interaction of
technological, economic, social, societal, and individual changes.
IOT is being implemented in construction for data gratification and safeguarding of products.
Manufacturers are now leveraging digital technology by integrating Big Data and the Internet of
Things in its products and services. The new range of intelligent machines exhibits the blend of
technology and digital innovation to meet the demand for world-class machines to build India’s Next-
Gen Infrastructure. They are all aimed at improving the overall customer experience by providing all
the important information in real-time.
Mini excavator used for a slew of different tasks
Along with the ever-demanding big projects, there is always a need to work on small sites, which
frankly could be a bit costly at times. In this regard, Mini excavators are becoming increasingly
popular. The midsize machines these mini excavators borrow features from both the big and small
class machines. Features like hydraulic quick attach, enclosed cabs with heat and air conditioning,
rubber over steel tracks have come down from the bigger machine class while the backfill blade,
center pivot boom and zero tail swing design are features that have migrated up from the smaller
diggers. The compact size of the machines means that the machine can be operated in cramped
spaces with less moving space. It is a lot easier using this machine at busy places like roadways, in
small alleys, near houses, buildings and other infrastructure etc. The machine works well in places
where it’s bigger counterparts cannot work well due to the size and the smaller ones due to lack of
power.
The mini excavator provides various attachment options making the machine more versatile. Given
the fact that this machine pumps more hydraulic fluid per minute, the machine can operate with a
number of attachments, especially larger buckets thereby improving cycle time and overall
productivity. One of the major draws of mini excavators is that you can use them for a slew of
different tasks. The sheer number of possible attachments and the light frame are what make the
mini excavator such a versatile machine.

Mini Excavator
Efficient fuel consumption of excavators
Modern excavator design is not just about productivity, ease of service and maintenance and fuel
efficiency. manufacturers are also putting more and more effort into improving operator comfort and
making machines easier to use. Fuel is one of the largest expenses for most construction companies.
Modern manufacturers have fitted their machines with fuel-saving technology and offer many
different fuel-saving services. Reducing fuel consumption by improving efficiency not only saves
money for companies but also helps reduce their impact on the environment. Every litre of diesel fuel
saved means there is 2.6kg less carbon dioxide released into the atmosphere.
Machines are now using the auto engine shutdown feature. It operates much in the same way as the
auto-idle feature. Instead of switching to idle mode, the machine’s engine will shut down after five
minutes of inactivity. After four minutes of inactivity, the machine will give a 60-second warning that
the engine will shut down. After the sixty-second period is up, the machine’s engine will switch off.
This feature helps to cut down on emissions when the machine is idle. A machine can be left idle 40-
60% of operating time which contributes significantly to fuel consumption. Excavator manufacturers
are continually trying to improve their machines to reduce operating costs and improve fuel efficiency.
A key focus has been getting maximum production out of the machine. “We always try to maximize
cubic yards per hour.
Conclusion
Every manufacturer is updating its excavator models and trying to come up with a more intelligent
automation system than the previous model of the same. Newer excavator models typically offer
gains in both fuel efficiency and productivity. The interesting trend that market players are seeing is
that the sizes of the machines which are popular are now becoming larger in size, so the market is
definitely moving towards larger machines. This demand for bigger machines is directly related to the
larger infrastructural projects declared. But there are scopes for smaller projects as well, like the rural
road program, swachh bharat abhiyan, or like semi-urban infrastructure or building of schools or

medium to small scale projects the traditional machinery works really well. The demand for the
excavator is underpinned by several macro and microeconomic factors impacting the sectoral growth
across various countries. It really comes down to the individual owner and what they’re looking for.
Are they looking for pricing? Are they looking for fuel-efficiency? Are they looking for operating costs
over the lifespan of the machine? Or are they driven by brand loyalty?
