Excavator Hydraulics

Based on statistical data, there was a significant increase in demand for Earthmoving and Mining Equipment, with hydraulic excavators accounting for approximately 24% of the overall growth, which amounted to nearly 23%. With the rising demand for construction equipment, it becomes crucial to determine where to invest. Excavators are robust machines that endure rigorous usage due to the nature of their work. They are utilized for a wide range of tasks, including digging trenches, lifting debris, and excavating mines. Excavators serve diverse needs in industries such as mining, road construction, building construction, and demolition.

Affecting factors

While the performance of excavators holds importance, their durability is of even greater significance. Small discrepancies in the quality of these machines can have a substantial impact on their durability. When assessing the durability of excavators, several factors should be considered. Careful consideration must be given to the potential hazards associated with mishandling these machines when making a purchase decision. The following factors can help in evaluating the durability of excavators during the procurement process:

Electrical harness

The electrical harnesses on the excavator should be waterproof to avoid any mishap at the place of work. Also, the harnesses should be placed in such a way that is easily accessible from the ground level and can be checked regularly. 

Boom and arm

The most important factor while checking the durability of the excavator is to look for the boom and arm of the product. These are the parts that take up most of the hard work of the machine.  All the booms and arms are covered by steel plates. However, the difference comes in the thickness of the plates. The thicker these plates, the more durable your machine is. It is necessary that these parts are nicely covered and even better if you could get a warranty for these parts while purchasing an excavator. 

Upper and lower frame

Another factor to look out for when purchasing a durable excavator is the strength of the frames of the machine. Since this equipment has a rough usage, the frame is put under a lot of stress. Hence, it is important to look out for frames that are designed well and have greater strength. 

Wear plate between arm and bucket

Usually there is a lateral wear plate between the arm and bucket. If the excavator isn’t well designed, the plate would have to be cut off and re-built again. A wear plate that is well-made wears off less and is durable for a longer period of time. 

Track motor cover

The track motor covers should be there with fully recessed areas to protect the bolt heads from damage. A lot of excavators in the market have exposed bolt heads which leads to damage in the early life stage of the machine. 

Slew ring grease bath

The slew ring is a rotational element that supports the heavy but slowly oscillating loads that the excavator picks out. The seal of the slew ring should be raised and thick enough to keep the water out and also easily accessible to check whether the water got in.

While the aforementioned factors provide a foundational understanding for selecting an excavator, there are additional measures that can be taken to prolong its lifespan. Regular inspections and maintenance are of utmost importance to ensure the machine’s durability.

The telematics system of your excavator serves as a valuable tool in extending its life. Paying attention to alerts and promptly contacting your dealer to discuss support options is crucial. Furthermore, it is essential to promptly address any damages incurred by the machine. Delayed action can lead to further deterioration and potential damage to unaffected components. Regularly inspecting fire extinguishers and water tanks is also necessary to ensure the smooth operation of your excavator.

There are a number of companies manufacturing one of the most durable and highly reliable excavators, Sany India being one of them. These machines require minimum maintenance and provide greater ROI in the long run. 

Spending some extra time each day on the maintenance of it will not only improve your machine’s durability but also improve the efficiency of it.
