Verified model comparison
Select compaction equipment from the material and project specification, then compare the complete working package.
The 815 tamping-foot configuration and CS56B smooth-drum reference use different contact and compaction systems. Obtain material classification, moisture and project acceptance requirements before choosing equipment. Machine mass by itself does not determine the required passes or achieved density.
The 815 reference includes a blade package, while the CS56B drum width and carrier dimensions describe another arrangement. Confirm any padfoot shell or optional attachment separately. Blade width, machine width and effective compacting contact are not interchangeable fields.
Inspect tamping tips and wheel cleaners on the 815, or drum, scraper and vibration system on the CS56B. Check articulation, drive and service records on both. Use a project-approved trial or testing process to establish the working method; this comparison does not prescribe an engineered pass schedule.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.

The 815 is a tamping-wheel soil compactor with a straight blade for spreading. It belongs in earthwork compaction research rather than the dedicated landfill-compactor class.
ExploreSingle-drum soil compactor. A padfoot shell or optional blade changes its configuration, rather than creating another model classification.
ExploreCarry utilization, fuel, wear, attachments and transport into an editable planning model.
ExploreNo winner is declared. Job fit depends on configuration, condition, dealer support, attachments, transport and cost assumptions beyond these published figures.
