Product Description
The ERM85C High-Performance Tamping Rammer is a premier industrial-grade solution designed for contractors who require maximum compaction power in a walk-behind unit. Driven by the legendary Honda GX160 5.5HP gasoline engine, this machine—commonly known as a “Jumping Jack”—delivers a massive 13KN impact force, making it ideal for the most challenging soil stabilization projects.
At 90kg, the ERM85C is specifically weighted to provide deeper reaching compaction than standard models. It features a reinforced structural frame and advanced vibration damping to ensure a perfectly level and hard-wearing surface finish. Whether you are working on municipal utility trenches, bridge abutments, or building foundations, the ERM85C offers the reliability and crushing power needed to eliminate air pockets in cohesive and granular soils effectively.

Key Features
-
Original Honda GX160 Motor: Features a world-class 4-stroke petrol engine, renowned for effortless pull-starts, fuel efficiency, and global service support.
-
Superior 90kg Static Load: The heavy-duty chassis provides higher static pressure, leading to significantly better compaction density in fewer passes.
-
High-Elasticity Ribbed Bellows: Outfitted with premium yellow polyurethane bellows for maximum flexibility and resistance to chemical corrosion and aging.
-
Vibration-Isolated Control Handle: Professional-grade shock mounts isolate vibrations from the operator, allowing for comfortable, high-precision steering during long shifts.
-
Triple-Layer Air Filtration: High-capacity air cleaners protect the engine from fine job-site dust, drastically extending the service life of the machine.
-
Hardened Steel Base Plate: Laminated wood and steel base plate design absorbs secondary vibrations while providing a clean, professional-grade finish.
-
Industrial Protection Cage: Features a reinforced steel frame to protect the engine from impacts and an integrated lifting hook for easy site transport.
Applications
-
High-Density Trenching: Essential for compacting soil and gravel backfill around large-diameter pipelines and sewage systems.
-
Foundation Stabilization: The perfect tool for prepping sub-grade soil before pouring concrete slabs for industrial and residential buildings.
-
Municipal Road Repair: Ideal for asphalt patching, pothole maintenance, and sidewalk construction where space is restricted.
-
Civil Engineering Works: Highly effective for compacting around bridge abutments, culverts, and retaining wall foundations.
-
Confined Spaces: Specifically engineered to reach corners, narrow walkways, and pillar bases where large rollers cannot operate.
