Tamping Rammer Honda GX160 – Petrol Jumping Jack, 3-3.5T Impact

The Jamshedji Honda tamping rammer is a petrol jumping jack soil compactor powered by a 5.5 HP Honda GX160 engine, delivering 3–3.5 tonnes of impact force at 700 blows per minute and compacting to a depth of 300 mm. Also called a dhumas machine or earth rammer, it compacts soil, sand, gravel and asphalt in trenches, foundations, pits, backfill and around structures — the confined places a plate compactor or roller cannot reach. Weight is 85 kg with a 340 × 280 mm plate.

Why a rammer rather than a plate compactor

A plate compactor works the surface. A tamping rammer drives energy downward in a narrow column, which is what cohesive soils and clay backfill actually need — and it does it in a 340 mm footprint that fits inside a service trench.

That is why rammers are specified for trench backfill around pipes and cables, column and footing foundations, pits, and the strips alongside walls and kerbs. Compaction to 300 mm depth in those locations is what stops the settlement that later cracks a slab or dips a road patch.

Petrol or diesel — how to choose

Jamshedji supplies rammers in both. This Honda petrol machine gives 3–3.5 tonnes of impact at 85 kg. The diesel tamping rammer gives 5 tonnes at 130 kg.

Take the petrol machine where the rammer has to be lifted in and out of trenches repeatedly, carried between locations, or worked on upper levels — 45 kg less matters when two men are handling it all day. It also starts easily and the Honda GX160 is serviceable in any Indian town.

Take the diesel machine for sustained heavy compaction on large earthworks, where the higher impact force and lower fuel cost per hour outweigh the extra weight. For enclosed areas where exhaust is a problem, use the electric tamping rammer.

For open ground and sub-base work, the plate compactor covers area faster. For roads, car parks and large formation layers, see the double drum walk behind roller and single drum vibratory roller.
