Machine Introduction and History
The Ingersoll Rand smooth drum roller is a vital piece of heavy construction equipment widely used for soil, gravel, and asphalt compaction. The company, with a long-standing history in manufacturing quality construction machines, is well-regarded for its vibratory smooth drum rollers, which combine strength, reliability, and operator-friendly features. These machines are pivotal in road construction, foundations, and site prep work.
Key Specifications (Typical Model Example: SD70D)
Ingersoll Rand’s smooth drum rollers, specifically models like the SD70D, are stalwarts in the compaction world, blending power, versatility, and operator comfort. Their ability to efficiently compact a variety of soils with minimal operator fatigue makes them indispensable for road building and site preparation. With routine maintenance and attentive operation, these rollers ensure long-term durability and consistent compaction results, crucial for safe and lasting infrastructure.

Key Specifications (Typical Model Example: SD70D)
- Operating Weight: Around 15,750 lbs (7,144 kg).
- Engine: Turbocharged 4-cylinder engine with approximately 99 hp, providing reliable power and fuel efficiency.
- Drum Width: 66 inches (1.68 meters), offering a wide compaction path.
- Drum Diameter: 48 inches (1.22 meters).
- Vibration Frequency: Dual setting with high frequency approximately 33.8 Hz and low frequency 30.8 Hz.
- Centrifugal Force: Up to approximately 32,148 lbs in high vibration mode.
- Maximum Speed: About 9 mph (14.5 km/h).
- Fuel Capacity: 47 gallons (178 liters).
- Hydraulic Fluid Capacity: 22 gallons (83 liters).
- Operator Platform Height: Near 9.6 feet for good visibility.
- Tires: 14.9x24 6PR R3, supporting rough terrain stability.
- Unlike vibratory drum rollers, the smooth drum roller operates without a vibratory system but relies on static compaction, applying constant pressure for uniform surface leveling.
- The vibratory smooth drum roller can alternate between static and vibratory modes, which combine pressure with vibrations to compact effectively and efficiently.
- Vibratory rollers improve the breakdown of air pockets in granular soil by transmitting high-frequency waves, enhancing compaction depth and uniformity.
- Articulated steering and operator-friendly dashboards improve maneuverability and user control, optimizing job site productivity.
- Primary use in asphalt paving where smooth, dense surfaces are needed.
- Site preparation and compaction of cohesive and non-cohesive soils before building foundations.
- Ideal for smoothing gravel road bases and finishing layers.
- Used in urban infrastructure projects requiring reliable, consistent compaction over large surface areas.
- Regular inspection and maintenance of the hydraulic system preserve consistent drum operation.
- Proper lubrication of bearings and joints extends machine life and improves performance.
- Check engine air filters and cooling systems frequently to prevent overheating.
- Ensure drum vibrators and isolation mounts are serviced according to intervals to avoid premature failure.
- Static Compaction: Using weight alone to compress the ground without vibration.
- Vibratory Mode: Combining drum weight with vibration to improve soil particle arrangement.
- Centrifugal Force: The outward force generated by the vibrating drum aiding compaction.
- Articulated Steering: A pivoting mid-frame allowing enhanced turning radius and control.
- Hydraulic Fluid: Oil used to transmit power within machinery hydraulic systems.
