Hydraulic excavator models

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. 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.

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.

Operator-friendly excavator models

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 the 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.

In 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 customization helps interact better with the operator. So customization of voice recognition systems is mandatory in this part. Not only in language, but simple software customization 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 customized software helps run troubleshooting and diagnostic measures to ensure the safety and efficacy of the machines. The manufacturers are now manufacturing machines as per the need of a particular terrain.

Excavator models with Advanced LiveLink Telematics Technology

Advanced telematics systems in excavators are now more advanced allowing construction firms to monitor both the location and performance of machinery and equipment. It enables them to ensure that effective and efficient use is being made of assets. Advanced telematics system provides information on Service, Operation and Security of machines. The manufacturers, customers and dealers will now have better control over their equipment usage. It also provides alerts on real-time location, maintenance alerts, machine and fleet hours etc., putting the user in complete control of the machine from any location. It can assist in ensuring that the machines are operated at the correct times and help to protect them from theft. The Fuel Reporting System in the telematics system further enables operators to see actual fuel consumption, improving control of fuel stocks and planning of fuel orders

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 models for small- mid-size projects

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.

Fuel-efficient excavator models

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.

Modern excavators 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.
