Cover Story May 2024

Mini excavators are witnessing greater traction across the globe, thanks to the fast paced construction, landscaping, and specialty equipment projects demanding these agile yet mighty machines. The continuous evolution of these mini marvels in terms of technology and advancement is shaping new age of construction where precision meets progress, and efficiency complements the sustainable expanse. This cover story tracks the innovative expanse of mini excavators alongside the upcoming trends in the global markets to imbibe & embrace the best in class machines… writes, PRERNA SHARMA.

In the world of construction, mini excavators have become a popular choice in several parts of the world, including Europe, China, and other geographies. These compact hydraulic machines possess a maximum operating capacity of six tonnes and have the ability to rotate a full 360 degrees.

Off-Highway Research’s recently released report on the mini excavator industry stated that sales of these compact excavators surpassed a remarkable 2,700 units last year. Although this figure may appear modest for a country that holds a prominent position among the top five global equipment markets, it is worth highlighting that mini excavators were virtually non-existent in India until about a decade and a half ago.

According to Off-Highway Research’s data, sales of mini excavators in India have experienced growth in four out of the last five years, with only a slight decline in 2020 due to Covid. In 2018, these sales surged by an impressive 29% compared to the previous year, reaching a total of 1,322 units. By 2022, this figure had more than doubled, soaring to an astounding 2,736 units. This surge in popularity shows no signs of abating, as sales witnessed a substantial 24% jump in the first half of 2023 compared to the same period in 2022.

As per Research & Markets, the mini excavator market has grown strongly in recent years and is further expected to grow from $7.88 billion in 2023 to $8.36 billion in 2024 at a CAGR of 6.1%. Urbanization and a substantial construction boom played pivotal roles, driving the demand for various construction-related activities. There was an increased emphasis on enhancing productivity across industries, particularly in utility and landscaping applications, where mini excavators demonstrated their versatility. Their adaptability in various construction sites, coupled with the ease of transportation, contributed significantly to their growing utilization. Moreover, government investments directed towards the construction sector also played a substantial role in fostering the growth observed during this period.

Mini excavators come primarily in two types such as wheeled and tracked. Wheeled versions utilize circular components rotating around axles for movement and transport. They are available in operational capacities less than 4 tons and between 4 to 10 tons, finding applications across various industries including agriculture, construction, and forestry.

Working in congested or confined areas can be challenging. To enable safe and confident work in confined spaces that are close to walls, on roadways or in urban areas, tail swing is an important consideration. Mini excavators are designed with the capability to make a 360-degree swing and have almost zero turning radius. The owning and operating cost associated with mini excavators is much lesser than backhoe loaders. Be it digging, trenching or filling job; mini excavators can perform all the tasks with speed and less fuel consumption. Further, mini excavators are highly versatile and can be fitted with various attachments to perform a multitude of jobs.

An interesting Sany article presented major benefits of mini excavators. These include:

Works efficiently in confined spaces: Mini excavators can be a great option when space is a major constraint as they can move and operate easily in tight areas. Also, they can pass through small gates and work easily at crowded sites like indoor projects.

Puts an end to labour shortage issues: Mini excavators can reduce the need for costly manual labour at the jobsite and hence, help companies in overcoming the issue of manual labour shortage. Mini excavators can also speed up the work at the jobsite like digging the area by mini excavator can be much faster than employing manual labour for the same task. This way, the manual labour which is freed can be redeployed in more skilled jobs. Thus, mini excavator, as opposed to manual labour, can allow contractors to meet deadlines and complete work with minimal quality defects, thereby, increasing speed and accuracy and reducing the need for rework.

Offers lower operating cost: Mini excavators can save money in all areas of operation as compared to the big excavators. They can do the same work, i.e., digging, backfilling, loading, lifting and loading at a lower cost while delivering the same performance as large excavators. In fact, they are more fuel-efficient as the large excavators.

Easy to operate: Mini excavators are very operator-friendly, and one can easily learn as to how to operate a mini excavator, and this reduces the training cost and time of the contractors.

Easier to transport or shift: Mini excavators are smaller in size and thus, can be easily loaded on to a trailer or small carrier and transported through narrow passages. Hence, they can help in eliminating the expensive logistics cost involved with moving large excavators.

Today’s modern machines are designed to dig every day, all day long, and every manufacturer strives to set themselves apart to make their machines at any size more comfortable for the operator. Intuitive and user-friendly designs enhance both operator comfort and performance and cab comfort is the key.

Featuring state-of-the-art lithium-ion battery technology, the conventional tail-swing Bobcat E19e provides the same power as its diesel-powered equivalents, with near-instantaneous torque. With a small footprint, zero emissions and an in-track swing frame, the E19e can work on small outdoor jobsites as well as indoors, where the alternative is manual labor. The E19e is powered by three lithium-ion batteries that provide a total capacity of 17.28 kWh. The batteries deliver high-energy density, long service life and require no routine maintenance.

Unlike standard-size excavators that typically excel in applications where there is a lot of space to manoeuvre, compact and mini excavators meet the demands of tight job sites, where you may have to work in confined spaces. Near-zero tail swing makes it easier to work around buildings, walls, guard rails and other structures.

Dig depth, reach, lift height, and bucket and lifting capacities all play roles in selecting the best excavator for the task. Ground conditions can also help determine the most appropriate size. For example, if minimizing turf disturbance is a factor, the smaller mini excavators exert lower ground pressure. This results in less damage to finished surfaces.

Transportability is an important consideration when the machine is frequently moved between job sites. Smaller mini excavators can often be pulled behind pickup trucks and may not require any special licensing requirements, depending on the gross combined weight rating.
