It would be hard to imagine a building or construction site where they do not use any compaction equipment. Reversible plate compactors are commonly used tools on these larger projects, whether they are commercial, residential, or roadworks. As opposed to a normal single-direction compactor, as the name suggests the reversible plate compactor for sale is able to operate equally in both directions – Forward & Reverse. Doing this allows the operator to control the compactor easily, increasing the maneuverability of these large machines on all surfaces.
Compactor baseplates are generally made from either steel or cast iron. The steel plates are generally used on the lighter, single-direction machines, this helps with the maneuvering and user experience, and also makes them more economical to purchase. Cast iron plates are more rigid and heavier helping to increase the compaction rate and reduce the plate flex. These are normally found on larger machines, like the reversible series.
The actual shape of the plate can also affect the compaction. If you are after the ease of movement then looking for a curved plate will greatly assist you when turning on any surface.
Another factor in how much compaction you will get out of a compactor is the centrifugal force. Centrifugal force is what gives the plate compactor its power. In essence the greater the centrifugal force generated by the compactor, the harder that plate thumps the surface. Generally speaking, a small plate compactor would generate roughly 500 kg-f to 1700 kg-f, whereas a large plate compactor can generate up to 4200 kg-f.
Eccentricity frequency (or Vibration frequency) is another major factor, this will dictate the number of times a compactor is able to hit the surface per minute. It is measured in VPM. You would want to choose a lower eccentric frequency if you are working with cohesive soil compaction. Alternatively, for more granular or asphalt type materials you would get more benefit out of higher VPM compactors.
However, it is the combination of weight, centrifugal force, vibration frequency, and moving speed that determines the effectiveness of the machine. Hence the reason to look for a manufacturer that has had years of experience and knowledge in perfecting this balance.
Another feature is the anti-vibration handle. What this does is cut down the vibration transfer from the base plate of the compactor to the operator's hands. Allowing a more comfortable experience for the operator working on the device.
If you are going to use your compactor to compact hot asphalt on road construction, or for a driveway, or a footpath, and you have a model that has a steel base plate, it is highly recommended that your compactor has a water tank and a built-in sprinkle bar. The water will then help to create a barrier between the cold steel plate of the compactor and the hot asphalt, helping prevent the asphalt from sticking to the plate. This is generally not required if you have a cast iron base plate.
As with all machinery, regular maintenance should be carried out on predetermined time (the instruction manual will have set times the machine should be inspected). With compactors, ensure it is carried out on the hard and level ground with the engines shut off. Also, note that the predetermined time for the periodical inspection is for if the compactor is working as expected. If you believe your compactor is not performing as intended, you should take it in for a service by a qualified person. It also pays to do a quick 360-degree inspection of your machine each day before use.
