70-84 in Smooth Drum Soil Compactor
The 70-84 in Smooth Drum Soil Compactor represents heavy production-grade vibratory rollers designed for roadway subgrade and large-scale earthwork. With drum widths spanning 2,100–2,130 mm and operating weights from 11,680 to 21,630 kg, these machines deliver compaction force between 256 and 375 kN. This size class occupies the third rung on the smooth drum soil compactor ladder, positioned between the 54-70 in band and the 84+ in heavy infrastructure rollers.

Spécifications clés
| Spécification | Plage typique | Signification |
|---|---|---|
| Drum Width | 82.7–83.9 in (2,100–2,130 mm) | Coverage width per pass on subgrade or base layers |
| Operating Weight | 25,750–47,686 lb (11,680–21,630 kg) | Mass range delivering static and dynamic compaction energy |
| Compaction Force | 256–375 kN | Vibratory amplitude force applied through the drum |
| Engine Power | 85–173 hp | Power for propulsion, vibration, and hydraulic systems |
| Fuel Tank Capacity | 250–410 liters | Diesel capacity supporting extended shift operation |
Comment choisir
The 70-84 in band suits production-scale roadway subgrade, highway embankments, and large commercial site preparation where wide-pass efficiency and heavy compaction force are required. Projects requiring greater maneuverability on confined municipal streets or subdivision infrastructure may be better served by the 54-70 in Smooth Drum Soil Compactor. Work involving interstate highway construction, airport runway bases, or heavy industrial pads typically demands the greater force and width of the 84+ in Smooth Drum Soil Compactor. Selection hinges on layer thickness targets, haul road widths, and whether site logistics can accommodate machines weighing up to 21,630 kg.
Ce que cette taille peut gérer
- Highway subgrade compaction for new roadway sections
- Commercial development site earthwork with engineered fill depths
- Municipal road reconstruction and base course preparation
- Industrial park grading and heavy-duty pavement foundations
- Dam embankment and levee construction compaction
- Large parking lot subgrade preparation for retail or distribution centers
Sécurité et opération
- Vibratory drum systems generate substantial ground-borne vibration; safe distances from trenches, foundations, and existing structures must be maintained
- Rollover protection structures (ROPS) and operator restraint systems standard on most models in this weight class
- Ground bearing pressure and compaction depth require coordination with geotechnical specifications to avoid over-compaction or localized settlement
- Articulated steering and wide turning radii demand clear sight lines and spotter communication in congested staging areas
Transport et logistique
- Heavy equipment lowboy or step-deck trailers rated for 12–22 metric tons
- Tractor units with appropriate fifth-wheel capacity for gross combined weights exceeding 30 tons
- Hydraulic ramps or dock loading; machines in this weight class require stable loading surfaces and coordination for over-dimensional transport permits in many jurisdictions
Alimentation
- Diesel fuel supply for 250–410 liter onboard tanks; consumption varies with vibration frequency and travel speed
- Machines typically operate full shifts on a single fill under continuous compaction duty
- No external power required; all propulsion, vibration, and steering systems run from onboard diesel engines
