Third Coast Equipment PR70H Premium Vibratory Rammer Honda GXR120 Engine 167lb Jumping Jack Compactor 3372 lbf Impact Force for Heavy Cohesive Soils

Dominate Cohesive Soil Compaction with the Massive Impact Force and Specialized Honda Power of the PR70H Premium Rammer

The Third Coast Equipment PR70H Premium Rammer is the ultimate heavy-hitter in confined space compaction, engineered for contractors who tackle the toughest soil conditions. Delivering a staggering 3,372 lbf of impact force, this 167 lb jumping jack is purpose-built to achieve maximum density in heavy clay and cohesive soils where lesser machines fail. Powered by the legendary Honda GXR120—an engine specifically designed to withstand the punishing vertical vibrations of high-output rammers—the PR70H provides the deep-stroke energy required for utility trenches, highway edge work, and structural foundation backfilling. Its slim 13.6-inch width ensures elite maneuverability in restricted areas, allowing you to meet strict municipal compaction specs with fewer passes and higher efficiency.

Built for industrial longevity, the PR70H introduces a game-changing aircraft-grade lifting cable system. While traditional rammers lift through the handle shock mounts—leading to frequent rubber failure and downtime—the PR70H lifts directly through the main frame, preserving the integrity of the vibration isolation system. Maintenance costs are further reduced by a two-stage air filtration system featuring a washable and reusable primary element, providing a critical line of defense against abrasive job site dust. Encased in rugged side and bottom steel engine guards and equipped with a weather-resistant hybrid shoe, the PR70H is an investment in durability that protects its own vital components while delivering the most aggressive compaction performance in its class.

Key Features

• High-Strength Lifting System: Integrated aircraft-grade cable lifts through the main frame to eliminate stress on handle shock mounts and extend tool life.
• Honda GXR120 Performance: Features a specialized 4 HP engine specifically built for the high-vibration vertical cycles of professional jumping jack compactors.
• Maximum Impact Energy: Delivers a class-leading 3,372 lbf of impact force at 720 BPM for superior soil density in cohesive materials.
• Dual-Stage Filtration: High-efficiency air system prevents dust ingestion; includes a washable first-stage filter to lower lifetime operating costs.
• Heavy-Duty Steel Protection: Comprehensive side and bottom engine guarding shields critical engine components from impacts and site hazards.
• Hybrid Compaction Shoe: A steel bottom shoe with a plastic core provides optimal vibration dampening for the operator while maintaining extreme durability.
• Deep-Stroke Compaction: A 3.4-inch shoe jump height allows for deep penetration into thick soil lifts, reducing the number of passes required.

Specifications

Pro-Tip: Due to the high impact force of the PR70H, it is essential to check the tightness of the shoe bolts after the first 5 hours of operation on a new machine. When working in deep utility trenches, ensure the rammer is not leaning against the trench walls; keeping the machine perfectly vertical allows the impact force to be directed 100% into the soil, maximizing the efficiency of each blow.
