500 kg Soil Compactors

500 kg soil compactors — serious compaction power for demanding groundwork

Soil compactors in the 500 kg class are built for heavy earthworks and road construction, where lighter plates simply cannot reach the bottom of the lift. Almost every machine of this size is a reversible vibratory plate, also described as a forward-and-reverse or two-way plate. Reversing works by shifting the phase between two counter-rotating exciters inside the housing: the same drive that pushes the plate forward pulls it back, or holds it compacting in one spot, without turning the machine inside a trench.

What the machine can actually achieve is governed by centrifugal force — the dynamic load transferred to the ground by the base plate on every vibration cycle, quoted in kilonewtons. The 500 kg class usually produces 50–70 kN across a plate 450–700 mm wide, whereas a light 100 kg forward plate manages only around 10–20 kN. That gap translates directly into the lift thickness you can bring up to the specified density. The category also groups stronger configurations with a higher centrifugal force and a wider base plate; exact figures are given on each product page.

NORWIT.PL supplies these machines for hard surfaces and loose granular material alike, in conditions where output and reliability decide the schedule. The range covers Wacker Neuson (DPU and BPU series), Bomag (BPR and BPH series) and Altrad Belle (RPC and RPX series).

Variants of 500 kg soil compactors

Within the class the machines differ mainly in engine type, starting system and whether compaction is measured on board. Ground conditions and contract requirements decide which combination makes sense.

Where 500 kg soil compactors are used

Machines of this class handle the more demanding end of construction work:

• Road construction — compacting sub-bases for roads, motorways, car parks and surfaces carrying heavy traffic.
• Large foundations for industrial plants, warehouse and production buildings, and other large-footprint structures.
• Compacting concrete, asphalt and other hard surfaces that call for high compaction force.
• Earthworks in difficult terrain, where the machine has to stay stable on uneven ground.
• Backfilling utility trenches for pipelines, cables and service connections, where working forward and back without turning saves real time.

Advantages of the 500 kg class

• High compaction force — the operating weight of around 500 kg turns exciter energy into a dynamic load that hard materials actually respond to.
• Output — large areas are compacted quickly, which keeps road and construction schedules on track.
• Stability — the frame and plate geometry keep the machine steady on uneven and broken ground.
• Versatility — one machine covers road, industrial and general construction duties.
• Reversible operation — travelling both ways and compacting on the spot cuts the number of manoeuvres in trenches and alongside structures.

Working output in practice

Output depends on centrifugal force, operating weight and travel speed. At a typical working speed of 20–30 m/min a 500 kg plate treats several hundred square metres of a lift per hour, and the specified degree of compaction is normally reached after 3–5 passes. Ground conditions matter as much as the machine: dry, well-graded granular fill compacts in fewer passes than material that is too wet or too dry.

How to choose a 500 kg soil compactor

A handful of parameters decide whether the machine will suit your sites:

• Centrifugal force — typically 50–70 kN in this class and more in the stronger configurations; the higher figure gives more reserve on stiff, hard-to-compact material.
• Operating weight — around 500 kg is the balance point between compaction energy and a machine one crew can still handle on site.
• Ground type — these plates excel on granular fill such as gravel, sand and crushed aggregate, and on hard surfaces; loams and clays respond far better to a rammer.
• Plate width — decides whether the machine fits the trench; narrow plates work around utilities, wide ones speed up open areas.
• Transport — at roughly 500 kg the machine is lifted by crane or hoist from its lifting eye, and needs a trailer rated for the load.

Compaction force versus travel speed

Force and speed together determine real output, but speed never substitutes for force. Driving too fast over a thick lift leaves the bottom of the layer under-compacted, and the fault only shows up later as settlement in the finished surface. Slower passes at full centrifugal force, repeated 3–5 times, give a result that survives handover testing.

Matching the machine to the job

The 500 kg class belongs on road works, foundation construction and industrial or infrastructure surfaces. For lighter duties — laying paving, landscaping, small repairs — a single-direction vibratory plate or a machine from a lower weight class is the better and cheaper tool.

The 500 kg class against other soil compactors

Operating weight is the simplest guide to the lift thickness a machine can handle. The ranges below are indicative — exact figures for each model are given on the product pages.

The brands available in this class are also grouped by make: Wacker Neuson compactors, Bomag compactors and Altrad Belle compactors. Every reversible machine, whatever its weight, sits in reversible vibratory plates, and wear parts and attachments are in compactor accessories.
