Masalta Diesel Tamping Rammer, 4.8 HP - MR85D

Diesel Tamping Rammer

Built specifically to tackle cohesive clays and mixed granular soils within restrictive excavations, the Masalta MR85D is a heavy-duty diesel tamping rammer engineered for maximum structural consolidation. Weighing 85 kg, this compactor is driven by a highly regarded 4.8 HP (3.5 kW) Yanmar L48 4-stroke engine, This specialized diesel configuration supplies immense low-end torque to generate an 18 kN compaction force. Striking the earth at a rapid pace of 690 blows per minute, it effectively drives out trapped air and moisture from thick soil layers, transforming loose dirt into a rock-solid, load-bearing base while maintaining excellent fuel economy and strictly lowered emissions.

Beyond sheer impact, structural maneuverability and operator protection dictate a rammer's true job-site value. The MR85D is meticulously balanced to translate engine power into a strictly vertical jumping stroke of 40 to 80 mm, preventing the unit from tipping or drifting sideways during operation. This precise weight distribution allows the rammer to advance naturally at a forward speed of 10 to 13 m/min, requiring minimal physical guidance from the operator. Downward energy is intensely focused through a rugged 340 x 285 mm steel and laminated wood shoe that easily navigates narrow trenches. To support long, grueling shifts, Masalta has integrated a heavy-duty shock mount system to isolate severe vibrations from the steering handle, along with a dual-layer air filtration setup and an approximately 2.8-liter rust-free fuel tank that keeps the machine running flawlessly in extremely dusty, high-demand environments.

Key Features & Benefits:

• High-Impact Compaction: Generates an outstanding 18 kN of raw downward compaction force combined with an 85 kg operation mass to ensure maximum mechanical density across both cohesive and granular soil types.

• Premium Yanmar L48 Engine: Driven by a highly reliable 4.8 HP (3.5 kW) diesel engine that delivers a substantially stronger impact force while maintaining strict operational efficiency and lower emission consumption.

• High-Frequency Impact Rate: Systematically hits the target ground at approximately 690 blows per minute, rapidly breaking up internal air voids in fewer passes to accelerate site preparation time.

• Dynamic Jumping Stroke: Delivers a versatile and calculated vertical stroke of 40 to 80 mm, allowing for deeper soil penetration and superior layer-by-layer compaction within restrictive trenches.

• Productive Forward Speed: Self-propels seamlessly at a steady, controlled speed of 10 to 13 m/min, giving the operator ultimate control while moving efficiently through large foundational work areas.

• Optimized Plate Dimensions: Features a highly durable 340 x 285 mm laminated wood and steel shoe specifically engineered to absorb heavy vibration shocks while fitting perfectly into narrow and confined excavations.

• Flawless Operational Balance: Perfectly weighted to deliver ideal, uniform compaction through precisely controlled jumping motions that maintain full downward impact energy without unintentional tilting or drifting.

• Additional Air Filtration System: Features a specialized dual-layer filtration layout that supplies cleaner air directly into the engine block, actively preventing dust intrusion to extend overall engine life and enhance hardware durability.

• Heavy Shock Mount System: Built with an advanced internal dampening configuration that radically reduces transmitted hand-arm vibration (HAV), maximizing operator comfort and allowing for longer, less fatigue-inducing work intervals.

• Extended Fuel Capacity: Outfitted with an approximate 2.8-liter rust-free plastic tank, allowing for longer continuous run times on a reliable diesel fuel choice, thereby minimizing disruptive refueling stops.
