Excavator – Everything You Need To Know

Social News 10,July, 2021


Regardless of whether an organization is buying or renting heavy equipment, it is essential to take a comprehensive approach while investing in construction equipment. Heavy machinery is a lucrative component of any urban development that runs on efficiency. The role it plays is vast, in terms of the planning and execution process. Excavators are one aspect to a project that provide intensive aid to heavy-duty tasks such as digging trenches, lifting and crushing heavy materials as well as various types of ground work.


Over the years, the industry has witnessed a multi-faceted evolvement of Excavators. Leading manufacturers of the industry such as Hitachi, Liebherr, Komatsu, Volvo, Demag and many more have produced impressive models while implementing smart technology in order to double down on efficiency. In order to choose the right excavator for a project it is important to consider, the size, hydraulic systems and the maintenance expenses involved. An excavator essentially is powered by diesel to drive hydraulic pumps that enable the movements involved in heavy-duty tasks such as digging, crushing and moving. In order to ensure any construction project is run smoothly, it is imperative to ensure proper excavation, and in order to execute proper excavation, the right excavator must be put in use.



5 types of Excavators used in the industry:


Every excavator is made of three main components: A rotating cabin, a bucket and arms powered by hydraulics. The different types of Excavators are classified as Crawler-mounted, Truck-mounted, self-propelled excavators and rail/barge mounted excavators.


1- Hydraulic Shovel:

These machines are mainly used for mining and digging purposes. Due to the nature they are built for, Hydraulic shovels are accompanied by large buckets on the front end of the machine. It’s common among many construction project used for a variety of jobs. Although it’s seen to be more prevalent in mining projects, due to high powered efficiency, it is used in any project that requires the movement of large rocks, objects and minerals.


2- Dragline Excavator:

This type of excavator is especially popular in civil engineering works for the purpose of surface mining tasks such as site clearing, deep pile driving, harbor construction, many under-water projects and road works. The specialty of this machine is its digging depth, with model featuring a depth of roughly 213 feet. The dragline is a fairly large piece of machinery that are further categorized into two categories: the standard machines relevant to lifting cranes, and ones that are so heavily made that they have to be built on site! However, modern day operations favor the former type. These machines are so large that they are capable of even digging the ocean. The largest Dragline Excavator currently present in the market is the Joy Global’s 9020XPC.


3- Skid Steers:

The Skid Steers on the contrary, are comparatively small and compact machines that are responsible for tasks involving site cleaning, debris removal, digging pools and basically most projects involving residential work. Their compact build allows them to be more capable of working in narrow sites. Compared to standard excavators, this equipment has a bucket that faces away from the operator. They are however, not built to work on harsh and textured terrain due to their manufacturing.


4- Long Reach Excavator:

Another common type of excavator in the market is the long reach excavator. The main focus of this machinery is to operate within inaccessible locations or for areas that are hard to reach. This excavator features a lengthier arm compared to other types, and for this reason, it’s perfect for demolition projects that involves taking down walls, buildings, and all types of structural crumpling. Furthermore, its usage can be further enhanced through the addition of more parts such as: buckets, clamps, breaker and auger.


5- Suction Excavator:

A suction excavation is a type of excavator that utilizes vacuum in order to remove materials from inaccessible places, such as holes on the ground, as well as for tasks that involves debris removal. This machinery is operated from fan systems that creates the airflow and absorbs unwanted materials from the ground. The machine also has an air filter which enables it to further separate finer particles and dust. This is seen as a comparatively safer option for removing parts of the ground such as tree roots and other unwanted materials, than other types of excavators.




Investing in an Excavator is much more than simply finding the right fit for the project at hand, it is also important to consider budget costs and total costs of ownership before giving the ‘go-ahead’. One of the main factors that play into role for the fiscal aspect of owning an excavator is the time-frame it is required for and the budget allotment. Due to the varying nature of urban developments, many businesses have resorted to online marketplaces such as Machinery Gate, that feature sellers offering  convenient quarterly, monthly or annual payment options. In other cases, mid-to-large sized companies can also opt for instant ownership by purchasing the machine directly, loans as well as lease-to purchase options.

Furthermore, like any heavy machinery equipments, excavators are also accompanied by their own set of operating costs such as fuel, insurance and maintenance. Excavators are quite large machines and tend to be high on the scale of energy consumption. On an estimate, an excavator is known to require 1.2 gallons of fuel per hour.




According to research conducted by the Italian National Research Council, the standard test for the efficiency of a Hydraulic Excavator involves 4 working conditions including: soil leveling, trench digging, straight travelling and its idling standby. In order to keep the excavator working in top condition, it is necessary to examine its functionality in all the above working conditions. The basic maintenance routine of an excavator generally involves inspections for track tension, air filters, coolants and water levels. It is important to ensure the machine is functioning on the right levels of lubrication while monitoring all the other aspects to avoid depleting its efficiency.
