    What is compactor?

    Soil is a combination of minerals, water, air and organic matter. In the construction process, soil stabilization is essential. Equipment used to compress, increase soil compaction and strength is called a compactor or pitchfork.

    In the following, we will discuss the types of compactors that include plate and tamping compactors, and we will compare the price of the compactor for you, and we will discuss the important points when buying and selling a compactor.

    In fact, the compactors follow the soil to allow for concreting and subsequent operations such as concreting, columnarisation, removal of concrete air using a vibrator motor and vibrator hose, and smoothing of the concrete surface by fencing, troweling.

    The advantages of compacting (compressing)

    1- Increases load bearing capacity.
    2- Prevents soil subsidence.
    3- Provides soil stability.
    4- Reduce swelling, shrinkage and permeability of liquids in the soil.
    5- Prevents damage such as soil freezing.


    Types of compactor

    1- Plate compactor

    2- Tamping rammer


    Plate compactor

    Plate compactor or plate compressor, also known as manual compactor, is one of the most essential building equipment that is used for compression and compaction of different types of soil, sand.

    This compactor can be used on sidewalks, Kopak mountain roads and places where rollers cannot be used.

    One of the main reasons for using these compactors is their large surface area, which is related to the ground surface. Each of the plate compactors has a separate story, but most of them consist of a heavy steel plate that is installed on the base of the device and support.

    It has different designs and accessories. But the core of all of them consists of a smooth, heavy plate that is moved or vibrated up and down by a gasoline or diesel engine.

    Also, plate compactors vary in size, strength, and mechanism of action. One of the main identification factors in compactors is their small screen dimensions.

    Plate compactors or forward-facing compactors are used in smaller dimensions for low work areas.

    Main factors in choosing plate compactor type

    1- What is the required compression force?

    One of the most important aspects to consider when using a compactor is the amount of compression force required, the amount of impact force appropriate depending on the base material you put in, and how the material will look after the impact.

    Make sure the amount of power you need for your job, low compression can cause serious problems on the road. If you feel that you are saving money by buying a smaller compactor, the troubles you may face in the future will eliminate all of these savings.

    2- What area do we want to hit?

    Work area is the main and most important factor for choosing the right compactor. Of course, a larger screen compactor covers more space at each work step, but the speed of the device is also included in the calculations.

    Different compactors have different speeds, the speed of which is measured in meters per minute. Another important issue is the importance of the dimensions of the device screen.

    If you have a compact screen with a slightly larger screen size but a much slower motion, the larger compactor may not work for you. You just have to be more discriminating with the help you render toward other people.

    One of the most important things to keep in mind when buying a page compactor is that it fits in well with your work conditions. If you buy a device based on the fact that you only use it once for a specific job, you may reach a device that is not suitable for other parts of your business.


    3- What features do we expect from the compactor?

    Most plate compactors are almost basic machines with very similar specifications. The main difference is in the forward motion characteristics or the reciprocating motion of the device.

    Moving forward compactors only move in the forward direction, but reversible compactors can move in both reverse and forward directions.

    How heavy-duty (reversible) plate compactors work

    Depending on the job situation and the type of compression you do, you will be able to determine which features will be more valuable to you.

    In general, reversible compactors work better in tighter areas because you don't have to turn the device and can easily move in two directions.

    Another issue that is very important is the shape of the page. The shape of the screen will help you overcome various work challenges and easily work in tighter spaces.

    Reversible plate compactors with large screen dimensions create more compressive strength than forward plate compactors.

    The plate compactors’ application

    1- Used in places where there is a lot of work maneuver and space is not limited.

    2- To track and build different infrastructures.

    3- Road construction, landscaping, asphalt repairs, sidewalk construction, yard and parking.

    4- Used to compress soil, sand, gravel and asphalt.

    Plate compactors advantages

    1- It has large screen dimensions for large spaces

    2- Reasonable price compared to frog compactors and high tonnage compactors

    3- Due to the large size of the screen and the spread of force, the possibility of damage to the soil is less.

    4- They have a simple mechanism and their maintenance is very simple.


    Tamping rammers

    A tamping rammer is a machine that beats the ground and traps soil particles, but it works differently than a plate compactor. Instead of using vibration to settle the soil, the device uses impact force to compress particles.

    Another name for this compactor is the jumping compactor, and the reason for this naming is the type of movement of the device, which has a high height and a jumping position like kangaroo.

    How a tamping rammer works

    A tamping rammer, also known as a bird jack, works by lifting the device's foot off the ground and hitting the ground with a heavy blow, which means increasing compression depth and maneuverability. And the function in pits and limited spaces is work.

    Vertical design of this compactors is due to the fact that most of them are able to work in places where work spaces are limited and difficult to work, such as channels. The small shock absorber plate and the large impact make it easy to work with without any problems.

    How the compactor works for you:

    1. Compacters are compact devices with a small base level.

    2. Their design makes it easy to maneuver.

    3. Their compaction depth can be greater than that of a vibrating plate compactor.

    4. They work differently from a vibrating plate compressor, allowing you to compress different levels.


    Tamping rammer’s application

    1- Limited space and places where there is no room for maneuver.

    2- Canal construction, drilling, foundation construction, asphalt repairs.


    3- For special applications and places where it is not possible to use plate compactors.


    Tamping rammers’ advantages

    1- Narrow cars with a small screen are therefore easy to transport.

    2- Their design allows them to have excellent maneuverability in limited spaces.

    3- They are much deeper than plate compactors.

    4 - How they work is completely different from plate compactors, which makes it possible to use them to compress different materials.

    Plate compactor or tamping rammer?

    Two of the most common devices used to compress and pound soil are plate compactors and tamping rammers.

    Customers are never sure which device may be better or more efficient. Here are some parameters that will help you choose between the two devices.

    1- The type of soil that we want to compact

    When choosing between a plate compactor and a frog, it is important to understand the differences between different types of soil. This will help you determine the type of equipment needed to achieve the best results.

    In general, there are two different types of soil: 1. Seed 2. Cohesive and sticky.

    Seed soil for compacting

    Seed soils such as sand are loose soils that can be compacted without considering whether they are wet or dry. They tend to collapse when removed and do not have good adhesion, so they cannot usually be molded like cohesive soils.

    Cohesive soils for compacting

    Cohesive soils usually contain large amounts of clay and are held together tightly. They need a certain amount of moisture to compress. If they are too wet or too dry, the possibility of air bubbles and improper compression will increase.

    Comparing the features of plate compactor and tamping rammer

    Here are the main features of the two devices that will fully guide you to choose.

    When you want to compact interconnected soils, tamping rammers work great because of the size of the screen. The smaller screen size creates a direct focus, which is very useful for soils that require more compression force.

    Due to their slim and stylish design, tamping rammers are ideal for narrow channels and spaces where there is no maneuverability.

    Tamping rammers have the ability to compress soil deeper than plate compactors because the force of the plate is more vertical and straight. Therefore, more thickness can be added to each layer of soil, which accelerates the process of filling and compressing holes or pits.

    Compacters are ideal for working with grain soils because they use vibration to dissolve the seeds in the soil. Plate compactors are larger in size than tamping rammers, which means that the weight and compaction force are distributed over a larger area, which helps to spread the material better.

    Also, due to the ideal design and performance, plate compactors are more efficient for large and flat areas.

    Two common mistakes in buying a compactor
    1- The importance of beating the compactor too much.

    You may think and worry that you can't compress the soil too much, too much compression will increase the soil's resistance, right? No

    Every substance has a breaking point. Excessive pounding causes the soil to crumble and reduces its ability to strengthen and build up due to the separation that occurs in the soil composition. Excessive pounding causes weakness, not strength.

    Think of it this way: If you have a mass of small stones and want to flatten them with a hammer, you can do this with the right amount of force, but if you keep hitting them, they will start to break into pieces. They will shrink and eventually you will have a completely different sand than the material you started with. As a result, excessive compression will break down the material in the soil and change your composition.

    Sometimes you can tell if your device is overheating. If the device appears to be operating abnormally, this could be a sign that the soil is over-compressed.

    2- Low compression stroke

    Low bumps can be the result of the following:

    1- In the first stage, not having a large device to do the job can be the result of insufficient beating.

    2- If the operator does not work enough with the compactor and does not pass the required passes for his beating.

    Inadequate posture and height can also lead to poor soil compaction, as the soil surface becomes more compacted, equipment impact is reduced, and most of the impact energy is returned to the machine itself. Soils with high height and depth can cause problems in plowing.


    Improper pounding can cause unbalanced and uneven sitting. Because the soil is not compacted properly, it cannot effectively withstand the weight of the structure. For these obvious reasons, an unbalanced session can lead to structural problems.

    Check soil specifications to accurately calculate the density

    For large-scale urban construction projects, an expert engineer who is familiar with the type of soil and the percentage of different materials in the soil usually identifies and approves the appropriate compaction rate, but in small projects it is important to have key points. Remember, for example, that you are fully confident that you have the right equipment for the job, as well as the type of soil you are working with.

    These will significantly improve the performance and results of your work and prevent excessive compression or low soil compaction of the desired location.
