Whether you’re preparing to compact various types of soils, crushed aggregates, or hot mix asphalt, selecting the right plate compactor for the job cannot be underestimated. There are certain characteristics that all quality compactors should have, and certain compactors that only perform well with particular types of soil and job sites.
By value, not by price
Considering all variables, including compaction requirements and plate compactor specifications, is essential to achieve the best possible result. A machine may be inexpensive but it won’t get the job done. An expensive machine may have great specifications, but it is impossible to handle without difficulty. It is best to ensure that the chosen machine is one that can deliver the required compaction value.
Verification of requirements
Matching the right compactor plate to the specific characteristics of the job is a matter of checking the requirements. Determine the type of soil and the desired compaction depth, along with site conditions, such as the 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 is part of a plate compactor is most often measured in width. The average size of a plate is between 15 and 25 inches. Generating around 3,000 pounds of centrifugal force, the breadth and weight of the compactor is as important a measure of value to gain as plate size. Steel plates that conduct heat more quickly are a better choice for compacting hot asphalt than cast iron. The shape of the motherboard is also a consideration, as it affects compaction. The best is a curved plate.
Comfort in handling
Operator handles on plate compactors are vital to the overall efficiency of the machine. Unless the operator is comfortable doing the job, the job will progress inefficiently. Ensuring that the 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 the storage location.
Engine types
An important consideration in plate compactors is the type of motor. Especially when working longer jobs, engine reliability is vital. Some brands have specialized in engines that give high performance in machines such as a compactor. The best include Honda, Subaru, Kohler, Yanmar, and Lombardini. ‘Vibrations per minute’ (VPM) are another factor when choosing the right compactor. The lower eccentric frequencies are better for use in cohesive soils and the higher VPM for granular materials and asphalt.
Compaction quality
There are a few additional things to think about when making sure to choose the correct compactor, including compaction quality. The overall design of the machine is also vital to its ease of maintenance and longevity.
