Upgraded for 2025, the SupremeEquip Tamper Rammer is built for professionals who demand power, precision, and lasting durability on tough jobsites. With enhanced components, improved build quality, and real Honda performance, this jumping jack rammer is ideal for contractors, municipalities, and rental fleets.
This model delivers a true 12.0 kN impact force powered by the reliable 3 HP Honda GX100 4-stroke engine—EPA and CARB certified. It's engineered to meet today’s jobsite demands, including nuclear density testing and field compaction tests.
✔️ True Compaction Power: 12 kN (2,698 lbf) of continuous impact force—not exaggerated marketing claims.
✔️ Upgraded German Bellows: Stronger, thicker, and more flexible to resist cracking and extend lifespan under daily use.
✔️ High-Capacity Fuel Tank: New compliant design increases runtime between refueling stops.
✔️ Compact Frame Redesign: Slimmer profile fits tight trenches while maintaining optimal balance and height.
✔️ Polyurethane Tamper Foot: Heavy-duty boot for better shock absorption and weight control.
✔️ Oversized Fasteners: Larger screws, nuts, and bolts simplify field service and quick repairs.
