Types of earth moving machineries

Moving tons of soil or rock is no small feat, which is why earth moving machinery comes into play. This type of heavy-duty construction equipment is engineered to handle the largest volumes with ease, speed and precision. Excavators are a well-known workhorse among this family of machines, known for their hydraulic arms that can dig deep trenches, loading capacity. Their agility allows them to maneuver on job sites with ease, whether opening foundations or for massive loading tasks. Bulldozers have a large, flat, bladed front that can push a massive amount of soil or debris from one area to another. They are commonly seen in grading and leveling, as well as in clearing sites of vegetation and debris. Loaders also come in many types to transport earth materials around a site. They typically roll up and scoop up materials, and the operator can then choose to dump it wherever it needs to go. Backhoe loaders are excavators fitted with a scoop on the back, allowing for efficient working and maneuverability. Accessories and attachments for loaders and excavators may include clamshells, hydraulic thumbs, or quick-change sand buckets that can increase functionality.

Similar to a loader but usually at a larger scale is the motor grader, characterized by its high-powered engine and lengthy flat blade. It excels in achieving precision grading and levelling thanks to its adjustable blade. Relying on sheer horsepower, the compactor then consolidates the soil or rock by applying a huge downward force that is also linked to the engine. While the area of application is less, their weight, especially under-area contact, is usually massive. Dump trucks allows one to haul material away from the job site to a different location. Equipped with an open bed and a hydraulic lift system, they are able to unload the material efficiently by tilting the dump bed. The tractor hauler consists of a powerful truck where a chassis and trailer combination is used to transport a large trailer over long distances. Then there are excavators with special add-ons like a dredging bucket that can help to remove loose or excess deepwater materials from the bed of water bodies.

As the scale of construction projects increases, so does the need for speedy and reliable earth-moving machinery. Whether demolishing an entire structure or clearing out a designated zone, specialized loaders are being adapted to tackle specific projects. This can take the form of a larger motor grader or compactor that is used on a highway construction project. Technologies such as telematics, autonomous driving and machine learning are being integrated into these machines. They can, for instance, track where they are on a construction site or the number of hours that the equipment has run. This helps construction companies to schedule maintenance for their machines and prevent any downtime. Autonomous earth-moving machines can make decisions based on data collected from sensors, and future machines may be capable of learning and adapting to different environments.

Specifications & Maintenance of Earth-Moving Machineries

Proper and regular maintenance can prolong the life of the moving machinery in earthwork and help it perform better. Detailing a scheduled maintenance plan is essential for a heavy-duty machine. The first step is to make note of the manufacturer's instructions, as it can differ depending on the make and model of the vehicle.

Some parts will need regular lubrication to prevent friction and overheating, such as bearings, tracks or chains, bucket joints, swing points, hinges, and roller axles. Using high-quality lubricant is a good idea, as it can help the machine withstand higher loads. Lubricate parts that come into contact with the ground or water and those exposed to excess heat and friction. Fitting the right lubrication helps keep dirt out and allows for easy cleaning and application.

The cooling system will need maintenance so it doesn't affect the working performance of the machine, which is vital for air-cooled engines. Keep an eye out for blockages in areas that need optimal cooling, like radiator fins and cooling fans. It is also essential to monitor the coolant level in the reservoir and look for leaks and other damages.

• Mini Excavator:

  The maintenance schedule is part of the engine's health. Monitor changes in the engine's performance before and after using additives to protect against wear and tear. Regular oil and fuel filter changes are essential to avoid engine damage. Other parts that need regular checkups include:

  • Daily machine inspection for leakage, air vent, oil, water, and fuel tank full.
  • Cylinder, Boom, Arm, Bucket, and Swing Bearings: Clean and lubricate every 50 hours of work.
  • A daily inspection for loose parts, blockage in oil passages, and oil leakage around pumps and motors.
  • Check battery connections and electrolyte levels; clean the terminals every month.
  • Check track tension, superstructure, and undercarriage for wear and tear, clean every month.
  • Every year, change the fuel pump, injection nozzle, and exhaust valve.

• Bulldozer:

  Other than the blade, focal parts requiring attention in a bulldozer are the drive chain, idler and sprockets, bogies, wheels, and undercarriage. They bear the weight and pressure while moving earth. Other than the undercarriage tracks, special attention needs to be paid to the drive chain due to the load factor. Ensure all gear connections are smooth, and they work without interruption, as they support the heavy load shifting in earthwork.

  The engine parts and their coordinated movement can make or break the insertion operational element of a bulldozer. Keep these engine parts in mint condition by following the maintenance schedule and going through the manual thoroughly. Apart from the drive chain, some other critical components of a bulldozer machinery that require regular inspection and cleaning are:

  • Idlers require lubrication every 25 hours; irregularity check, clean after every 50 hours of work.
  • Drive chain, check and adjust its tension every 50 hours, apply lubricant to the joints every 200 hours, and irregularity under the chain housing after 100 hours.
  • Environmental conditions in which the machine works affect its health. In places with high humidity and frequent rains or corrosive surroundings, check and replace seals and gaskets more frequently.

• Skid Steer Loader:

  Some of the characteristic features of a skid steer loader are its rigid frame and lift arms that connect to the wheels directly. While the basic functioning is moving earth, it does so efficiently with its particular system that requires regular care and maintenance. Other than the engine, battery, and hydraulic system that have been previously discussed, here are some other components to check on a skid steer loader:

  • Check tracks every 20 hours and water each month. Watch for irregularities in idlers and rollers and replace them on demand.
  • Inspect bucket cutting edges and replace them as needed. Other parts that require frequent inspections are lift arm grease fittings, seat belt and operator presence switch, battery terminals and electrolytes, safety shields and guards, fan blades and shrouds, and hydraulic lines and fittings.
  • Check the engine belts and hoses; clean and lubricate the swing bearings.

  Every 250 to 500 hours of operation, a detailed inspection of the structural integrity is to be done. Cracks and strains around the frame, lift arms, and all rubber parts suspended in the air are to be checked with care. Skid loader steers are sensitive, so the hydraulic oil is to be replaced as per the instruction manually and following proper disposal guidelines for fluid changes.

Applications of earth-moving machinery

• Land clearing and site preparation

  Earth-moving machines, such as bulldozers and excavators, are used to clear vegetation, trees, and debris from a land area to prepare a construction site for a new project. Initially, a dozer blade or a bucket of a grader is used to level a land area.

• Excavation and trenching

  When digging or moving large volumes of soil and rock materials from one part of a site to another or creating trenches for laying foundations, utility pipes, and cables or excavating for landscaping features, an excavator or backhoe is used.

• Digging foundations and footings

  After the site has been cleared and leveled, the next step is to dig the foundations and footings of the building using an excavator or backhoe.

• Land grading and leveling

  Land grading is the process of leveling an uneven area and is done to create a level base for construction. A level site is critical for ensuring the structural integrity of the building to be constructed. A grader or dozer is used to haul and spread soil or gravel to create the desired slope or elevation with a high level of accuracy.

• Creating and maintaining drainage systems

  An excavator, a backhoe-loader, or a compact track loader can be used to create ditches, drains, and culverts and to maintain them later. Proper drainage systems help control the movement of water on agricultural land and construction sites. They help prevent erosion and protect the integrity of the building or any other structure.

• Landscaping and earth shaping

  Earth-moving machines can also be used for landscaping and creating features like berms, mounds, and retaining walls using soil or rock materials. When landscaping, operators use excavators, backhoes, or skid-steer loaders to precisely move soil and rock in a controlled and careful manner.

How to choose earth moving machinery

Selecting proper earth-moving equipment for construction needs requires careful consideration of several important factors such as project demands, machinery condition and operator availability.

First, assess the nature of the task at hand and its size. Determine if it involves loading, excavation, digging or transporting. Take into account factors like area dimensions, soil type as well as any existing structures or overhead lines nearby. Match these requirements with appropriate pieces of earth moving equipment. For instance, choose a backhoe loader or excavator for excavation projects and opt for a bulldozer for tasks that involve clearing or grading land.

Second, project requirements also include an assessment of the required capacity and reach. When selecting earth moving machinery, it's crucial to consider the capacity and reach of the equipment. Make sure that the machinery can handle the weights and volumes of materials needed for the project. Also, ensure that the equipment has the necessary reach to work effectively within the project's dimensions. Additionally, laydown space and access to the site should be considered. Make sure that the selected equipment can safely navigate through the project site to reach the work areas.

Third, consider using used earth-moving machinery. These second-hand machines are cost-efficient options. Check their working condition. Make sure the moving parts, including tracks and tyres, are in good condition. Look for any leakage in hydraulic lines. The investment in used heavy equipment helps in providing affordable construction solutions to business buyers.

Fourth, the availability of skilled operators is an important requirement to consider when selecting earth-moving machines. Some complicated pieces of equipment such as excavators and skid steer loaders may require advanced skill sets.
