Meiwa Gasoline Tamping Rammer, 4HP Engine, Made in Japan - RT70R

Gasoline Jumping Rammer 4HP

The MEIWA RT70R Gasoline Tamping Rammer delivers exactly that, bringing authentic Japanese engineering directly to trenches, utility pipelines, and demanding backfill sites. Driving this dynamic compaction tool is a highly efficient Robin EH12D 4-stroke engine, generating a peak output of 4.0 HP. This powerhouse configuration actively eliminates the hassle of fuel-oil mixing while producing a staggering 12.7 kN (1,300 kgf) of impact force, aggressively driving out trapped air and moisture from heavy, cohesive soils to create a perfectly dense base.

Navigating tight, confined municipal spaces where larger ride-on rollers simply cannot operate is where the RT70R truly excels. Outfitted with a specialized 330 x 270 mm laminated steel and wood shoe, the compactor powerfully strikes the earth between 600 to 650 times per minute. Despite its aggressive downward energy, operator comfort remains a strictly engineered priority; an advanced shock-absorbing handle isolates kinetic feedback, heavily reducing the vibration transferred to the user's arms. With a brisk forward travel speed of up to 13 meters per minute and a low-maintenance design featuring a 2.5-liter polymer fuel tank, the compactor stands as a formidable asset for civil engineering teams focused on maximizing daily site productivity.

Key Features & Benefits:

• High-Impact Compaction: Forges up to 12.7 kN (1,300 kgf) of raw, downward impact force, allowing civil contractors to aggressively drive out trapped air and achieve proper soil density quickly.

• Dependable Robin Engine: Powered by a robust, low-emission Robin EH12D 4-stroke motor delivering consistent RPMs under heavy loads.

• Anti-Vibration Architecture: The operational handle integrates heavy-duty rubber shock mounts that absorb structural kinetic energy, significantly reducing hand-arm vibration and preventing operator fatigue.

• Laminated Steel Shoe: The 330 × 270 mm foot is meticulously constructed from high-tensile steel and laminated wood, allowing it to absorb intense ground impacts repeatedly without cracking or excessive wear.

• Rapid Forward Speed: Tuned to operate at a highly efficient forward travel speed of 10 to 13 meters per minute, empowering operators to cover up to 780 meters per hour in long pipeline trenches.

• Optimized Fuel Capacity: A rust-resistant 2.5-liter polymer fuel tank paired with a low consumption rate of 1.1 L/hr ensures continuous, uninterrupted operation, minimizing refueling downtime during critical shifts.

• Deep Soil Penetration: The combination of a high 650 vpm impact rate and a 40–60 mm jumping stroke generates excellent compaction results, particularly in challenging, heavy, and cohesive clay environments.

• Low Maintenance Layout: Designed with clear factory maintenance points, including a highly accessible oil gauge plug that enables mechanics to perform rapid, hassle-free pre-shift fluid inspections.

• Superior Japanese Engineering: Designed and assembled in Japan by MEIWA, utilizing strictly high-grade industrial materials to guarantee maximum structural integrity over years of commercial use.
