Mini excavators are finding increasing acceptance across projects, given their widening scope for varied applications, especially urban construction jobs where space is limited for larger machines to operate. NBM&CW reports
The rising need for construction equipment to work at constricted sites has been leading to rapid developments of newer technologies across the value chain, during the past decade. This is especially true for manufacturers of mini excavators who have been developing more advanced solutions, while also leveraging their R&D and design capabilities to produce smaller, more compact versions.
Mini excavators are highly specialized machines. The key to their performance, and thereby rising demand, is their ability to work in constricted spaces, with high speed, and undertake varied applications from urban constructions to specialized agricultural field jobs like trench digging, small canal works, sewage disposal, waste management, fisheries farming, etc. The list is endless.
With its versatile features, the equipment can also find application in small scale municipal pipeline works, park maintenance, building basements, etc. As light machines, they can be lifted by cranes to reach high-rise buildings for undertaking demolition work on any floors.
The Government’s new initiative to supply potable water to households through laying of water pipelines under the ‘har ghar jal’ program, will further widen the mini excavator’s scope of work, and increase its demand.
The market for mini excavators is expanding and becoming more competitive. According to industry estimates, the size of the mini excavator market in India during 2020 was 1530 units, up from the modest 300+ units in 2014.

As their demand and application scope increased, we have been packing them with a host of competitive features. Apart from the 360 degree revolving, as in any other excavator, our mini excavators offer boom swing, which assists in digging and loading in areas where full swing is not possible - as when working alongside a wall.
The compact frame of Tata Hitachi excavators is enhanced by the zero tail. This enables the operator to focus only on the front side operations in compact areas.
Tata Hitachi offers three variants of its mini excavators (2 ton to 3 ton), namely TMX20 neo, ZAXIS 23U, and ZAXIS 33U. The ZAXIS 23U and ZAXIS 33U feature the latest hydraulics and zero-tail swing. They have superior ergonomics, performance, and safety features. The operator station is protected by a ROPS/ TOPS structure. Their compact design makes them easy to transport in conventional and mini light axle pick-up trucks.
The zero tail swing of ZX20U and ZX33U allows them to operate in extremely compact spaces. Their full metallic cover provides higher durability, and they offer ease of maintenance as it is easy to access the machine parts. To make the machines suitable for Indian working conditions, we have fitted them with radial air filters and air pre-cleaners.
The TMX20 neo is the first ever mini excavator manufactured and sold in India. Its specialty is its simplicity and robustness.
All our mini excavators are built with most reliable Japanese engines, proven hydraulic systems, and durable structures. They are high performing, comfort driven, and offer ease of maintenance. Most importantly, they deliver higher fuel efficiency.
To suit multiple applications, our mini excavators come with a range of bucket options like general purpose bucket and narrow trench bucket, besides attachments like breakers, mechanical quick couplers, and augers.
To make our mini excavators more competitive, we have indigenized our 3T HEX to ZX33U, and will be doing the same for ZX20U shortly. We have also updated the TMX 20. This is because indigenisation will make our machines more economical. To promote our specialized mini excavators and backhoe loaders, we have set up a compact vertical, exclusively for their promotion, sales, after- sales etc, and we are also leveraging our dealer network to drive sales of our mini excavators.

Growing urbanization is triggering the growth of the mini excavator segment in India, where it accounts for 2-3% of the Excavation Industry, but in developed markets, it accounts for more than 50%. Contractors and rental companies are beginning to appreciate the versatility of the machine to work in confined space with higher efficiency, plus the operating cost of a conventional mini excavator is approximately one-third of that of a Backhoe Loader. In view of these advantages, demand for Mini Excavators in India has increased by 50% in the last 4 years. Also, the Government’s focus on projects like Swachh Bharat Abhiyan and Jal Jeevan Mission is giving a thrust to the Mini Excavator industry. We see the mini excavator market to continue to grow to around 5000 units in the next 2-3 years.

For example, the most ideal class of mini excavators is said to be in the 2-ton and the 3.5 ton. If anything lesser or more than that is deployed, by not calculating the indexed requirement, there can be a serious disruption in the operating cost. In view of this, we have been promoting Takeuchi’s TB219 (2- ton ) and TB235 (3.5 ton) mini excavators, as the most suitable for the Indian market.
Many rental companies in India deploy a lesser capacity excavator for a job which it may not be suitable for. We have seen this when working with a hydraulic rock breaker, which can create a return vibration during its operation and thereby create stress on the hydraulics or the parts, and consequently lead to chances of equipment failure. Ideally, a 3-ton machine, indexed to the work it has been assigned with the rated power, will be able to do light or heavy tasks more efficiently.
Takeuchi mini excavators have a spacious operator station, an automotive – styled interiors, and a powerful hydraulic system. The combination of superior operator comfort and precise control is the reason why Takeuchi mini excavators outperform competing machines. The mini excavators come with pre-fitted, pipeline adaptation kit to fit various attachments with ease, like rock breakers, augers, grapplers, etc.
Product support to Takeuchi mini excavators is rendered by Fine Equipments through its 35 + pan India dealers, who are adequately trained to ensure higher availability of the excavators.
The company keeps a close eye on upcoming projects, new government initiatives for infra development, and live tenders. Having a sizeable customer base, pan India, also enables us to access customers and promote our mini excavators and spread awareness on their utility.
