Whether you’re preparing to compact various types of soils, crushed aggregate, or hot mix asphalt, selecting the right plate compactor for the job can’t be underestimated. There are certain features that all quality compactors should have, and certain compactors that will only work well with particular soil types and job sites.
For value not for price
Considering all variables, including compaction requirements and compactor plate specifications, is essential to achieving the best possible result. A machine may be cheap but not get the job done. An expensive machine may have great specifications but be impossible to operate without difficulty. It is best to ensure that the chosen machine is one that can deliver the required compaction value.
Requirements check
Matching the correct plate compactor to the job specifications is a matter of verifying the requirements. Determine soil type and desired compaction depth, along with site conditions such as size and accessibility of the area to be compacted. In urban areas, narrow roads and high traffic areas, it is easier to maneuver and use a lighter single plate compactor.
plate size
The plate that forms part of a plate compactor is usually measured in width. The average size of a dinner plate is 15 to 25 inches. Generating around 3,000 pounds of centrifugal force, the compactor’s width and weight are just as important a measure of value as the size of the plate. Steel plates that conduct heat more quickly are a better choice for compacting hot asphalt than cast iron. The shape of the base plate is also a consideration as it affects compaction. A curved plate is better.
Driving comfort
The operator handles on the compactor plates are vital to the overall efficiency of the machine. Unless the operator is comfortable doing the job, the job will progress inefficiently. Ensuring that operator handles are fully adjustable and have padded grips is one of the most essential criteria for operator comfort. These handles are also convenient for transporting the compactor from the job site to storage.
engine types
An important consideration in plate compactors is the type of motor. Especially when working on longer jobs, engine reliability is vital. Some brands have specialized in engines that give high performance in machines such as a compactor. The best ones include Honda, Subaru, Kohler, Yanmar, and Lombardini. ‘Vibrations per minute’ (VPM) is another factor in choosing the right compactor. The lower eccentric frequencies are better for use on cohesive soils and the higher VPMs for granular materials and asphalt.
Compaction quality
There are a few additional things to think about when making sure you choose the right compactor, including quality of compaction. The overall design of the machine is also vital to the easy maintenance and longevity of the machine.
