What Is the Wacker Neuson BS50-2 High Altitude Vibratory Rammer?

The Wacker Neuson BS50-2 High Altitude Vibratory Rammer 2 Stroke - Jumping Jack Tamping Rammer Compactor is a high-performance, fuel-efficient soil compactor built to excel where air is thinner and conditions are tougher. Unlike standard compactors, this model features engine calibrations designed specifically for elevations above 3,000 feet (approx. 900 meters).

Compact and powerful, this rammer uses a “jumping jack” motion that allows it to deliver strong compaction force through a narrow foot, making it perfect for tight spaces like trenches and around structures. Its specially adjusted 2-stroke engine ensures reliable performance without sacrificing power, even in places where typical engines struggle due to reduced oxygen.

---

Why High Altitude-Specific Design Matters

At higher elevations, air density decreases, which affects engine combustion and reduces horsepower. The BS50-2 High Altitude version tackles this problem by:

✅ Optimizing the carburetor to maintain the correct air-fuel ratio
✅ Delivering consistent impact force, preventing the loss of compaction power
✅ Reducing the risk of stalling and engine wear
✅ Maintaining fuel efficiency to lower operational costs

These features ensure reliable performance, which is especially critical on mountain construction sites, ski resorts, high-altitude highways, and similar projects.
