The 12-ton machine becomes the largest model in the Volvo soil compaction portfolio with an 84-inch smooth drum and operating weight of 26,565 pounds. Its specs are similar to the existing SD115 but with a 0.2-inch thicker drum shell and a heavier outer eccentric weight, which results in an additional 935 pounds of mass on the drum, increasing the static load and eccentric force for a different amplitude profile.
Superior performance
As terrain and material depths change, the ability to adjust dynamic drum forces is as simple as the flip of a switch on the SD125 model. Another switch adjusts the two drum frequencies to compensate for changing conditions, and a five-frequency feature is available as an option to further boost versatility and performance.
The center joint provides +/-35 degrees of articulation and +/-12 degrees of drum oscillation for stable yet flexible performance and greater operator comfort over rough terrain. Because the drum is in constant contact with the ground, compaction is smooth and uniform.
The additional static weight on the drum frame enhances stability and performance with the ability to negotiate up to 35 percent slopes for better gradeability. The angled frame allows higher clearance in the approach to steep slopes and while loading, eliminating the possibility of damaging the surface or the machine. The frame and articulation joint are covered by the Volvo lifetime frame and structure warranty.
A heavy-duty axle is integrated into the drivetrain for an efficient rear-wheel drive system. The No-Spin differential increases traction, eliminates tire slippage and improves gradeability, performance and productivity. A high-traction variant is available for demanding applications where additional torque is needed to tackle extreme slopes or thick lifts of loose material.
All three levels of Compact Assist software are available on the Volvo Co-Pilot in-cab tablet, allowing users to determine the visibility, mapping and reporting features that are most important to them.
More sustainable design
The SD125 features a powerful Tier 4 Final-compliant four-cylinder Volvo engine with 147.5 horsepower. Active DPF regeneration eliminates material build-up, further reducing emissions. The engine is backed by Volvo dealer service and parts support and a 1,000-hour warranty.
Additional features include:
- A hydraulically operated engine cooling fan that runs only when needed, reducing fuel consumption.
- Lower noise levels for operator comfort.
- Optional fan reverse for cleaning out the coolers.
- Volvo long-life coolant to protect the machine for up to 6,000 hours.
- Remote hydraulic test ports that can be configured to enable quick and easy hydraulic checkpoints without having to open the system.
In line with the Volvo commitment to safety, the emergency stop system shuts down the engine, applies the brakes and stops the machine’s movement if the operator rises from the seat for more than five seconds during operation.
The SD125 will be available for order in North America during the first half of 2025.
