"70KG" is the machine's approximate operating weight (about 70 kilograms), and "14KN" is the nominal impact/ramming force (14 kilonewtons). These numbers indicate the unit's mass and compaction force — useful for comparing power and portability against other rammers.
A double air filter uses two stages of filtration (typically a primary and a secondary element) to remove more dust and particles before air reaches the engine. This improves engine longevity and reliability, especially in dusty jobsite conditions.
Tamping rammers are ideal for cohesive and mixed soils (clay, silt, sand with fines) and for trenches, around foundations, backfills, and paving preparations. They are especially effective in confined areas where plate compactors cannot reach.
Specific engine and start method depend on the model/configuration supplied. Many rammers use a small gasoline engine (2- or 4-stroke) with recoil start; some models offer electric start or diesel variants. Check the seller's specification for exact engine type and starting system.
Effective compaction depth depends on soil type and number of passes. Rammers typically compact to depths of several tens of centimeters per pass (commonly up to ~200–400 mm in loose fill when using multiple passes). For accurate depth predictions, run field tests on your soil type.
At about 70 kg, the unit is relatively heavy. Transport between sites is usually done with a vehicle; on-site movement can require two people or the use of a lifting/transport bracket or wheeled trolley accessory. Follow safe lifting practices and local regulations.
Typical maintenance includes daily checks (fuel, oil, visible damage), cleaning or replacing the air filter (double-filter element), inspecting the foot and bellows, checking and tightening fasteners, and changing engine oil/spark plugs at manufacturer-recommended intervals. Always follow the supplied service manual.
Most common spare parts — air filters, foot/tamping plates, bellows, spark plugs, carburetor parts — are widely available for popular rammer engines and models. Confirm spare-part availability with the supplier or manufacturer for the exact model you purchase.
Wear hearing protection, safety boots, eye protection, gloves, and a dust mask as needed. Ensure stable footing, keep bystanders away, use vibration-dampening handles if equipped, and take regular breaks to reduce operator fatigue and vibration exposure. Follow local regulations regarding PPE and vibration exposure limits.
Rammers generate significant noise (typical of small internal-combustion compaction equipment). Use hearing protection and, where possible, operate during hours that minimize disturbance. Some models offer mufflers or quieter engine options — check the spec sheet.
Rammers produce a concentrated impact suitable for soils and sub-bases but are not intended for finished asphalt or delicate surfaces. Use protective measures or choose a different compactor type (e.g., plate compactor) for final surface works.
Common accessories include replacement and specialty tamping feet (different shapes/sizes), transport trolleys or wheel kits, lifting brackets, spare bellows, and protective covers. Availability varies by supplier.
