Wacker Neuson BS50-2 High Altitude Vibratory Rammer 2 Stroke – The Ultimate Jumping Jack Tamping Rammer Compactor for Challenging Conditions
When it comes to soil compaction at high altitudes and on tough terrain, contractors know the right equipment makes all the difference. That’s why the Wacker Neuson BS50-2 High Altitude Vibratory Rammer 2 Stroke - Jumping Jack Tamping Rammer Compactor stands out as an essential tool for professionals who work where the air is thin and reliability is non-negotiable. This purpose-built rammer delivers unmatched compaction force, ergonomic operation, and proven durability — all engineered to perform in high-altitude environments where standard machines can struggle.
In this detailed guide, we’ll break down everything you need to know about the Wacker Neuson BS50-2 High Altitude Vibratory Rammer 2 Stroke - Jumping Jack Tamping Rammer Compactor: from what makes it unique and its key features to why it’s a smart investment for construction crews, utility contractors, and landscapers working in mountainous or elevated regions.
What is the Wacker Neuson BS50-2 High Altitude Vibratory Rammer?
The Wacker Neuson BS50-2 High Altitude Vibratory Rammer is a compact, powerful, and specialized compactor specifically designed to maintain peak performance in high-altitude environments, typically those above 3,000 feet (approximately 1,000 meters). Often called a jumping jack tamping rammer compactor, this tool uses a vertical “jumping” motion to deliver high impact force through a narrow foot, making it perfect for compacting cohesive soils in tight spaces.
Powered by Wacker Neuson's proven WM 80 2-stroke engine, this model is specially calibrated to compensate for thinner air at elevation. This means operators get the same reliable power output whether working at sea level or on mountain construction sites.
Why Choose the BS50-2 High Altitude Model?
At higher elevations, air density decreases, affecting engine performance in standard equipment. The BS50-2 High Altitude model includes carburetor and engine adjustments to ensure:
✅ Consistent power delivery
✅ Reduced risk of engine stalling or loss of compaction force
✅ Better fuel efficiency
✅ Longer engine life by running at correct air-fuel mixture
For contractors and utility teams working in mountainous regions, these differences mean real savings in time, fuel, and maintenance.
Key Features of the Wacker Neuson BS50-2 High Altitude Vibratory Rammer 2 Stroke - Jumping Jack Tamping Rammer Compactor
1. High-Performance WM 80 2-Stroke Engine
Built for demanding use, the WM 80 engine is engineered for reliability and optimized for altitude, ensuring steady power output and strong compaction performance without the need for constant manual carburetor adjustments.
2. Compact and Agile Design
Weighing approximately 59 kg (130 lbs) and featuring a slim footplate, the BS50-2 is highly maneuverable, making it ideal for trench work, tight corners, and around structures.
3. Superior Compaction Force
Delivering around 1,350 kg of impact force (about 13.2 kN), this jumping jack tamping rammer compactor handles cohesive soils like clay and mixed materials, ensuring proper density with fewer passes.
4. Ergonomic Operation
Its vibration-damped handle, balanced design, and manageable weight reduce operator fatigue and the risk of hand-arm vibration syndrome (HAVS), allowing teams to work longer and more comfortably.
5. Automatic Oil Injection System
Eliminates the need for manual pre-mixing of fuel and oil. Simply fill the separate oil tank, and the system delivers the right amount automatically, preventing costly engine damage from improper mixtures.
6. Robust, Maintenance-Friendly Construction
Reinforced components and an easy-access design make routine checks — like air filter cleaning and spark plug replacement — quick and straightforward, keeping downtime minimal.
