The Sakai RS65 is a high-performance tamping rammer (also known as a “jumping jack”) designed for compacting cohesive and semi-cohesive soils in confined spaces like trenches and foundations.
It is well-regarded for its durability and reduced operator fatigue.
Below are the technical specifications for the Sakai RS65 (70 kg class):

Engine Details

The RS65 is most commonly equipped with a Honda engine, though some regional variations may feature a Robin/Subaru engine.

Starting System: Recoil starter.
Fuel Tank Capacity: ~2.0 Liters (0.5 gal).
Carburetor: Diaphragm type (allows operation at various angles).

Key Features & Design

Shock Isolation: Features a superior shock isolation system that significantly reduces the vibration transferred to the operator’s hands.
Tapered Shoe: The ramming shoe has a tapered front corner, which helps protect the side edges of pavement and improves visibility.
Integrated Controls: Features an “all-in-one” lever that controls the fuel-off, engine-stop, and throttle functions simultaneously.
Durability: Includes a steel cage to mitigate damage from accidental drops and a multi-stage air cleaner system to extend engine life in dusty environments.

Common Applications

Trench Work: Gas, water, electric, and communication line installations.
Foundations: Compacting around footings and backfill for residential or commercial buildings.
Confined Spaces: Ideal for narrow areas where larger plate compactors cannot maneuver.
