Functions, Types, How to Work, and Maintenance of Loader Heavy Equipment

Posted on


Loaders heavy equipment, or more commonly known as a loader, is a type of construction machine that is used to move materials such as soil, gravel, sand, stones, or other materials from one place to another. Loaders are commonly used in a variety of industries, including construction, mining, agriculture, and other industries that involve the manipulation of heavy materials.

Loaders usually have strong wheels or chains to run the machine, and are equipped with a bucket (scraper) located at the front. These buckets can be lifted, fanned and tilted to collect material from the ground and load it onto trucks, conveyors or other storage areas.

Loaders are an important part of the construction and material handling industries because of their ability to move large quantities of material quickly and efficiently. They come in a variety of sizes and capacities, to suit different project needs. Check out the full article only on TransTRACK!

Loader Tool function

Loader heavy equipment has several main functions in various industries such as construction, mining, agriculture, and others. Some of its main functions include:

Material Loading

The most common function of a loader is to load materials such as earth, gravel, sand, stones and other materials onto trucks, conveyors or other conveyances. The loader is equipped with a bucket that can be filled with material from the ground or piles, then the bucket is lifted and dumped into the conveyer.


While not as popular as excavators for digging tasks, some types of loaders can also be used to dig holes, trenches, or canals. This is especially true for loaders that have tilt and swivel bucket capabilities.

Material Transfer (Material Handling)

Loaders are also used to move materials from one place to another at the project site. They can pick up material from one area and deliver it to another, helping to organize a more efficient workflow.

Land Leveling (Grading)

Some loaders are equipped with special attachments or tools that allow them to level or smooth the ground. It can be used in ground leveling, road building or surface preparation before advanced construction.

It is important to remember that loader capabilities vary depending on the type. Wheel loaders and chain loaders have different characteristics, and their capabilities also depend on their size, lift, and type of attachments used. In the modern construction industry, loaders are an important element in increasing the productivity and efficiency of work involving the manipulation of heavy materials.

Loader Tool Types

Below are some of the types of loader tools that actually exist:

Wheel Loader

This is the most common type of loader encountered. Wheel loaders have wheels and are used to load material from ground level onto trucks or other storage areas. They have buckets that can be lifted and steered to collect materials.

Skid Steer Loaders

Skid steer loader is a compact type of loader. They have excellent maneuverability and are often used in tight areas. They had independently steerable fixed wheels on the right and left sides, which allowed 360 degree rotation on the spot.

Track Loader (Chain Loader)

This type of loader is similar to a wheel loader but uses a chain like an excavator. This provides better traction on uneven or soft surfaces, such as unpaved dirt or mining terrain.


Backhoe is a type of heavy equipment that is generally used for digging and excavation work. It is a combination of excavator and loader, combining digging capabilities with material loading capabilities. Backhoes usually have a bucket that can be raised and adjusted with arms that can rotate 180 degrees, allowing them to carry out digging work in hard-to-reach areas.

So, the types of loaders are Wheel Loaders, Skid Steer Loaders, and Track Loaders. The backhoe, although important in construction, is a type of heavy excavator and has a predominant digging function.

How Loader Heavy Equipment Works

The workings of loader heavy equipment, especially wheel loaders, involve several stages that generally occur in the material loading process. Here are the general steps in how a loader machine works:

tools preparation

The loader operator must check the condition of the equipment, including check the level of fuel, hydraulic oil and various other systems. They must also ensure that the work area is safe to operate.

Loader Position

Loaders are placed near piles of material to be loaded, or in areas where materials will be picked up.

Bucket Adjustment

The operator adjusts the bucket position to approach the material precisely. This can involve raising or lowering the bucket as well as tilting it as needed.

Material Retrieval

The bucket is lowered to the surface of the material to be loaded. Then, the bucket is opened or dug into the material to fill the bucket with material.

Material Lift

After the bucket is filled, the operator lifts the bucket using the tool’s hydraulic system. The bucket is lifted from the surface of the material with the material in it.

Transferring and Loading

After the bucket is lifted, the operator moves the loader to the place where the material will be loaded, such as a truck or conveyor. Here, the operator can tilt the bucket to pour material where it needs to go.

Disassembly of Materials

After the bucket is empty, the operator can return to the pile of materials to repeat the process of picking up and loading materials. This process is repeated until loading is complete.

Finish and Cleaning

After loading is complete, the operator ensures that the work area is clean and safe. The loader can be safely parked for future use.

Routine Care

During and after operation, routine maintenance such as checking fluid level, tool cleaning and other maintenance should also be carried out to ensure good tool performance.

It is important to remember that how loader machines work can vary depending on the type of loader, the size of the equipment, and the type of material being loaded. Trained operators have a key role in running loaders safely and efficiently.

Loader Heavy Equipment Maintenance

Regular and proper maintenance of loader heavy equipment is essential to ensure optimal performance, extend tool life, and maintain operator and work environment safety. Here are some steps in the maintenance of loader heavy equipment:

Routine Maintenance Planning

Create a routine maintenance schedule based on the tool manufacturer’s recommendations. This includes daily, weekly, monthly, and special maintenance based on the number of operating hours of the equipment.

Daily Checkup

Before operating the loader, perform a visual inspection of various important components such as tires, hydraulic systems, cooling systems, fuel systems, braking systems, and others. Make sure there are no leaks or problems appearing.

Change Oil and Filter

Engine oil, hydraulic oil and filters should be changed according to the schedule recommended by the manufacturer. Clean, well-functioning oil and filters are important to maintain optimal tool performance.


Make sure all lubrication points on the machine are lubricated regularly. This includes parts that have repetitive motions such as joints and hydraulic components.


Keep the tool clean from dirt, dust and other materials that can damage components. Regular cleaning helps prevent excessive wear.

Check Tires

Check the air pressure in the tires and make sure the tires are in good condition. Tires that are too low in pressure or damaged can affect the stability and performance of the tool.

Electrical Check

Check the appliance’s electrical and electrical systems, including lights, horn and charging system. Make sure all electrical functions work properly.

Hydraulic System Maintenance

The hydraulic system is an important part of the loader. Check the condition of hoses, connections and hydraulic fluid regularly. Make sure there are no leaks and that the hydraulic fluid is of good quality.

Cooling System Maintenance

The cooling system must function properly to prevent overheating. Clean the radiator from dirt and make sure the coolant is at the appropriate level.

Operators Training

Ensure loader tool operators are properly trained in proper use, operating procedures and basic maintenance.

Maintenance Track Record

Record all maintenance activities that have been carried out, including the date and type of maintenance. This helps in setting up subsequent maintenance schedules and monitoring machine performance.

Special Care

In addition to routine maintenance, be sure to carry out special maintenance according to the manufacturer’s recommendations or the maintenance guidelines provided.

Performing proper and regular maintenance will help keep loader machines in top condition, avoid costly breakdowns and increase the service life of the machine.
