Sizing TC Series Hydraulic Compactors


The compactor must be sized properly for the carrier on which it will be mounted and the work it will need to do.

Based on Type of Work:

Most applications require the soil under a road or load bearing surface to be compacted to 95% or greater, then the density of the original material removed. This can be achieved provided the soil is the correct type and has sufficient moisture.

Uniform materials like clay and sand are difficult to compact.  Unprocessed dirt, pit run gravel, or soil with non-uniform particle size is preferred. The moisture content in most material should be less than 10% for best results.

Assuming soil conditions are correct, all models of compactors will provide good compaction, therefore, the key factor becomes how much material will need to be compacted per hour. The major factor determining the rate of production is the acceptable lift height (depth of fill to be compacted).  Compactors with high impulse energy are permitted to use a higher lift of material, which significantly increases productivity.

Refer to the ‘Production Rates’ information link provided for each compactor.

Based on Carrier Size:

The carrier that is selected to operate the plate compactor must have sufficient reach to compact the deepest area of the trench or excavation. Therefore, sizing the compactor based on the carrier size becomes the most important factor in choosing the correct sized compactor.

BTI has assigned a ‘Recommended Carrier Weight’ range to each compactor.  If the operating weight of the carrier falls within this range, the carrier will safely handle this model.  If the desired compactor falls outside of the recommended carrier weight range, the carrier lifting capacity and oil flow will need to be verified to ensure a proper fit.

Lifting Capacity:

Provided the weight of the compactor does not exceed the maximum lifting capacity of the carrier in any position, the carrier is assumed to be stable.  On most loader backhoes and excavators, the maximum lifting capacity is lowest when the boom is at full reach. This is the value that must be compared to the operating weight of the compactor.

Oil Flow:

A required oil flow range is specified for each compactor. Oil flow to the compactor within this range is adequate for operation. However, for maximum productivity the carrier should be capable of providing the maximum required flow. Compare the maximum oil flow requirement of the compactor with the oil flow capacity of the carrier. Remember the compactor will be operating at 1200-2200-psi (83-152 bar), therefore, oil flow should be evaluated at the
operating pressure.
