Sirl Diesel Tamping Rammer – 4.2 HP, Yanmar L48 Engine, Made in Portugal - SP85D

Heavy-Duty SIRL Diesel Tamping Rammer

When tackling cohesive soils, heavy clay, or mixed gravel in confined trenches, standard compaction equipment simply lacks the necessary punch. The Made in Portugal SIRL SP85D is a professional-grade Diesel Tamping Rammer purpose-built to conquer extreme groundwork and foundation repair. At the very core of this robust machine lies the 4.2 HP (3.3 kW) Yanmar L48 diesel engine. Renowned globally for its unparalleled reliability and fuel efficiency, this air-cooled powerhouse drives a massive 18 kN impact force into the ground at a rapid rate of 450 to 650 blows per minute. Operating at an optimal weight of 89 kg, the SP85D ensures deep, effective compaction reaching up to 65mm per pass, creating a rock-solid base that prevents future structural settling.

Because job sites are notoriously harsh and dusty, SIRL engineered this rammer for maximum endurance and minimal operator fatigue. The engine breathes clean air thanks to a specialized triple air filtration system, drastically extending its lifespan even in the worst conditions. The pounding force is transferred through a highly durable laminated wood and steel shoe (345 x 285 mm) designed to absorb lateral shocks and resist severe wear. For the operator, a precisely engineered low-vibration handle and ergonomically positioned throttle lever make controlling this aggressive machine surprisingly smooth. Completed with a heavy-duty protective frame with a transport peg, the SP85D is the ultimate, low-maintenance compaction solution for serious contractors.

Key Features & Benefits:

• Yanmar Diesel Power: Driven by the highly reliable, fuel-efficient 4.2 HP (3.3 kW) Yanmar L48 4-stroke diesel engine.
• Massive Compaction Force: Delivers a heavy-hitting 18 kN impact force at a rapid 450 - 650 vpm, perfect for deep trench and foundation compaction.
• Generates a massive 18 kN of impact force: To effectively compact cohesive clay, silt, and gravel up to 65mm deep.
• High-Durability Shoe: Features a heavily reinforced laminated wood and steel foot (345 x 285 mm) built specifically for maximum wear resistance and shock absorption.
• Triple Air Filter System: An advanced, multi-stage air filtration system guarantees clean intake, protecting the engine and prolonging its life in dusty environments.
• Operator Comfort: Engineered with a specialized low-vibration handle to significantly reduce operator fatigue and hand-arm stress during prolonged shifts.
• Protective Frame & Transport Peg: A heavy-duty steel engine guard prevents damage from accidental impacts, while the robust top peg facilitates safe lifting and crane transport.
• Precise Control: An ergonomically positioned accelerator throttle lever allows the operator to quickly and safely control the tamping speed.
