Brief intro of popular Heavy Infra Machinery

Heavy construction equipment are designed for executing construction tasks, involving earthwork or other other large infra jobs. There are different types of heavy equipment each having different application and required for different construction activities.

Given below is a list of the most used heavy infra equipment 


The modern range of Excavators come with factory fitted Advanced Telematics to providing real-time access to the operational activity and work report of your fleet of machines. It is the most in-demand heavy equipment because of its functioning terminology consisting of a boom, arm, bucket and cab on a rotating platform known as superstructure. The three main sections of an excavator are the undercarriage, the superstructure and the boom-arm. The undercarriage includes tracks, track frames, and travel motors. The superstructure includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The superstructure attaches to the undercarriage by way of a center pin and swing bearing. High-pressure oil is supplied to the tracks’ hydraulic motors through a hydraulic swivel at the axis of the pin, allowing the machine to slew 360° unhindered and thus provides the left-and-right movement.


Modern backhoes are powered by a better engine and deliver powerful performance and fast response time coupled with higher productivity and fuel savings. They are re-engineered from the ground up to deliver industry-leading backhoe breakout force, greater loader lift capacity/reach, and cab visibility. The new series of Backhoes have robust robotically welded two-piece structural frame design resulting in greater stability, performance and serviceability. The new heavy-duty front axle with double effect steering cylinder ensures all wheels remain in contact with the ground even on the roughest terrain, ensuring exceptional stability and reliability. The hydraulically shifted clutches allow the operator to change direction and travel speed on the go, while the control valves deliver smooth speed and direction shifts, resulting in smooth and accurate operation.

The bulldozer is iconic equipment in the class of machines known as heavy equipment. Also known as dozers, they are synonymous with power and reliability. They are equipped with a hydraulically operated horizontal blade for moving large quantities of earth, rock and other material. The dozer is mounted on tracks and uses its broad blade for land clearing, grading, placing and transporting materials. Dozers are used in construction projects, mines, agriculture and forestry. Bulldozer is equipped with a substantial blade used to push large quantities of soil, sand, rubble, or other such material during construction work and typically equipped at the rear with a ripper to loosen densely compacted materials. Bulldozers can be found on a wide range of sites, mines and quarries, military bases, heavy industry factories, engineering projects and farms.

Motor graders

New series motor graders are well-equipped models ideally suited for small-to-mid-size grading operations for municipalities, road maintenance and road construction. Modern graders deliver fuel-saving performance with minimal cost or maintenance. Models come standard with the productivity-boosting features operators want and are available as standard drive or 4WD. Motor graders are absolutely necessary equipment at any construction site. They are usually self-propelled machines with an adjustable blade. Typical motor grader models have three axles with the engine and cab situated above the rear axles at one end of the vehicle and a third axle at the front end of the vehicle with the blade in between. Motor graders are generally identified by their long adjustable blade and considered to be easy-to-use equipment.

Trenchers are designed for cutting narrow, straight trenches. Modern-day trenchers can produce trenches with perfect profiles in widths from 20 to 60 centimeters to a maximum depth of 2 meters. Dedicated trenchers are expensive and thus trencher attachments have become popular. These can be mounted on an excavator, backhoe loader or a skid steer loader. Trenchers with tungsten carbide teeth can be used to cut hard ground, concrete, asphalt and even soft rock. These machines are often used to dig trenches for pipes and cables.

Loaders are best suited for earthmoving, road construction, agricultural purposes, and also in large and small scale constructions. A loader is a heavy equipment machine used in construction to move aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled material, rock, sand, woodchips, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car). There are many types of loaders, which, depending on design and application, are called by various names, including hydrostatic loader, front-end loader, payloader, wheel loader, or skid-steer.

Pavers are designed to execute operations of Road construction or repair and reinstatement black top. The newer models give paving results of superior quality by having a heavier screed with tamper bars. They are designed to meet and surpass your needs in terms of precision, efficiency and ergonomics. The end result is an impressively high paving performance, including the achievement of excellent compaction values.


Soil / Tandem compactors combine climbing power, high centrifugal forces and 360-degree visibility to provide you with superior productivity and power. The compactor is equipped with unique features and robust structures that enable you to build strong roads. Whether it’s a single drum soil compactor or a vibratory tandem road roller, every compactor offers an efficiency which is more than what you expect. It optimizes the number of passes and enables you to monitor the operator’s performance with real-time compaction alerts.
Dump Trucks

New generation dump trucks can transport heavy loads quickly, easily and cost-effectively. Available in rigid or articulated versions with state-of-the-art designs, they are built around a powerful engine and are exceptionally strong machines. They guarantee complete driving safety, even at high speeds. From the transmission system and chassis to the axles and suspension, all the components are designed to handle grueling daily stresses for maximum reliability. Dump Trucks are typically used for hauling material over the road or around a job-site. They typically feature a cab and offer a hydraulic dump bed. Dump Trucks come in varying axle configurations, which typically limit the weight you are capable of hauling.
Pile driving equipment

Pile driving equipment is designed to align and hold piles in the correct position and to drive the piles into the ground. Equipment of this type can also be used for extracting piles from the ground. Pile-driving equipment includes a weight-lifting device and a driver, which is usually mounted on a excavator, or crane hoist. Pile-driving equipment is classified according to the principle used in operating the driver as impacting, vibratory, or rotary. It is designed to align and hold piles in the correct position and to drive the piles into the ground. Equipment of this type can also be used for extracting piles from the ground. 

Each type of heavy equipment serves an individualistic purpose, so while choosing, be sure the equipment serves your project needs. It’s important to choose the right piece of equipment for the job to maximize productivity and cost-effectiveness.
