Wacker Neuson WN BS70-2PLUS 4AS 2.7 HP Compaction Rammer

Description

Wacker Neuson BS70-2PLUS 4AS (2.7 HP) Compaction Rammer

The Wacker Neuson BS70-2PLUS 4AS Compaction Rammer is a high-performance vibratory tamping rammer (jumping jack) designed for professional soil compaction in trenches, foundations, and confined construction environments. Powered by a reliable 2.7 HP WM80 two-stroke, oil-injected engine, this machine delivers strong impact energy for deep and efficient compaction of cohesive and mixed soils such as clay, silt, and backfill.

The “2PLUS” series is engineered for improved durability, easier maintenance, and enhanced engine protection, while the 4AS air filtration system ensures long service life even in dusty job site conditions. Its narrow shoe and high-impact stroke make it ideal for tight trenches where larger equipment cannot operate.

Designed for contractors, utilities, and infrastructure work, the BS70-2PLUS combines power, efficiency, and operator comfort in a rugged, job site-ready design.

Key Features

• Powerful 2.7 HP WM80 engine with oil injection system

• Excellent performance on clay, silt, and backfill materials
• Designed for professional contractor and utility use

Applications

• Trench compaction
• Pipeline and utility installation
• Foundation and footing preparation
• Backfilling around structures and pipes
• Road repair and maintenance
• Confined-area soil compaction
• Civil engineering and infrastructure projects

Wacker Neuson WN BS70-2PLUS 4AS 2.7 HP Compaction Rammer: Buying Considerations

The Wacker Neuson BS70-2PLUS 4AS Compaction Rammer features a 2.7 HP WM80 oil-injected engine and delivers powerful soil compaction for trenches, foundations, and utility work. Designed for professional contractors, it offers durability, efficiency, and excellent performance in confined areas.

Before ordering the Wacker Neuson WN BS70-2PLUS 4AS 2.7 HP Compaction Rammer from Wacker Neuson, review the points below against your actual site conditions and workload. Published specifications describe the equipment under test conditions, and real-world performance depends on how closely your application matches those conditions. Buyers in the United States, Canada, and Asia should also confirm local voltage and frequency requirements, applicable safety or emissions standards, and freight or import logistics for the destination before finalizing an order.

What to Check Before You Buy

• Identify whether the material is granular, cohesive, or mixed – plate compactors (vibration) suit granular soils, while rammers (impact) suit cohesive soils like clay.
• Set lift thickness within the equipment's effective compaction depth and the project specification – exceeding it leaves a hidden loose layer under a compacted surface.
• Choose a footprint size that reaches edges and confined areas without damaging adjacent structures.
• Confirm the required compaction test method (Proctor density, etc.) and target percentage before starting work.

When should a rammer be used instead of a plate compactor?

Rammers deliver impact force suited to cohesive soils like clay and silt, where a plate compactor's vibration doesn't effectively penetrate below a thin surface crust. Trenches and confined cohesive-soil work are the classic rammer application.

For sizing help across the full Compaction Equipment category, compare specifications side by side before committing to a specific model, and confirm current pricing, availability, and freight details for your location. Keep the supplier data sheet and any acceptance criteria on record for future maintenance and replacement decisions.
