200 kg Soil Compactors

A soil compactor with an operating weight of about 200 kg generates centrifugal force in the 20–30 kN range, clearly above the 12–15 kN typical of light 90–100 kg machines. The greater mass and stronger exciter allow layers up to 40–50 cm thick to be compacted, whereas light compactors normally handle layers of 20–25 cm. The 200 kg class therefore belongs on road sub-bases, foundations and larger areas, while 90–100 kg models suit pavements, driveways and block paving.

A compactor with an operating weight of about 200 kg suits road sub-bases, car parks, manoeuvring yards, foundation backfill and service trenches. Centrifugal force of 20–30 kN together with a plate width of roughly 50–60 cm compacts layers of non-cohesive soil up to 40–50 cm thick in a single pass. Equipment in this class is also used for surface repairs and for consolidating ground before block paving is laid, where both output and the ability to manoeuvre in confined spaces matter.

A forward-travel compactor moves and compacts in one direction only, so on reaching an edge the operator has to pull it back by hand, which slows the job down on areas larger than a few dozen square metres. A reversible compactor switches between forward and backward travel without the operator changing position, reaching a travel speed of some 20–25 m/min in both directions at a vibration frequency of around 90–100 Hz. Reversible models have the edge in the 200 kg class — they compact trenches, ditches and the zone along foundation walls precisely, without walking the whole machine backwards.

A compactor of about 200 kg with centrifugal force of 20–30 kN works best on non-cohesive soils — sand, all-in aggregate and gravel, where the grains pack tightly under the vibration and pressure of the plate. Cohesive soils, meaning clays and silts, normally require compactors of greater mass (from 300 kg up) or static machines such as rollers, because vibration penetrates dense, plastic particles less effectively. The 200 kg class also copes well with aggregate mixes under surfaces and sub-bases in layers up to 40–50 cm thick.

A reversible compactor of about 200 kg usually has a working plate 50–60 cm wide, so it fits inside foundation trenches and service excavations wider than that figure, where forward-travel equipment manoeuvres more slowly. Being able to travel forward and backward without the operator changing position makes it possible to compact backfill right against a foundation wall without damaging the waterproofing. In a trench narrower than 50 cm or deeper than 1.2–1.5 m, a slim tamping rammer is often the better choice than a vibratory plate.

NORWIT.PL supplies soil compactors with an operating weight of about 200 kg primarily from Altrad Belle, Wacker Neuson and Bomag — manufacturers with long experience in equipment for compacting soil and surfaces. The range covers both reversible and forward-travel models, powered by combustion engines rated at roughly 4–6.5 kW. Which brand and model fits depends on the soil type, how often the machine will run and the budget available — we advise on the choice in line with the scope of the planned works.

The working plate alone on a 200 kg class compactor weighs around 60–80 kg, while the complete machine with engine, fuel tank and exciter reaches a total mass of roughly 190–210 kg. Loading it onto a trailer or into a van single-handed is awkward — ramps, a winch or a second person are recommended, and for frequent transport a trailer with an electric winch proves its worth. Moving around the site itself takes no extra effort, because the machine propels itself through the vibration of the exciter.

Operating a soil compactor of about 200 kg requires no formal operator licence under technical inspection regulations, because the machine is not subject to technical inspection supervision the way cranes or work platforms are. The employer must nevertheless train the operator in health and safety rules and in the operating manual for the specific model, and with a combustion engine of 4–6.5 kW must provide hearing protection (noise levels reach 100–105 dB) as well as protection against hand-transmitted vibration. In practice, construction firms run their own on-the-job training before allowing an employee to work with a compactor.
