Product Description
The ERM85 High-Performance Tamping Rammer is a top-tier industrial compaction tool designed for professional-grade soil stabilization. Driven by the legendary Honda GX160 5.5HP engine, this machine—commonly known as a “Jumping Jack”—delivers exceptional reliability and massive impact force for deep-reaching compaction.
With an increased operating weight of 85kg, the ERM85 provides the necessary downward pressure to eliminate air pockets in cohesive and granular soils more effectively than lighter models. Its heavy-duty construction is specifically optimized for harsh environments like utility trenches, narrow foundations, and road repair sites. Whether you are a municipal contractor or a landscaping professional, the ERM85 offers the perfect balance of power, precision, and longevity for all your earthwork needs.
