Engine-Powered Vibrating Plates: Petrol and Diesel, Forward and Reversible

Light vibrating plates (50–90 kg) suit paving slabs, paths and small asphalt repairs, medium plates (90–200 kg) compact foundations and roads, and heavy reversible plates (200–500 kg) handle thick layers and cohesive soils. Choose the weight according to the material and layer thickness. See how to choose a plate compactor.

Centrifugal force (kN) shows the strength of the vibratory action: 10–15 kN on light models, 15–30 kN on medium and 30–70 kN on heavy ones. Compaction depth depends on it, from 15–20 cm for light plates to 50–70 cm for heavy reversible models.

Forward plates move only ahead and suit open, flat areas, while reversible plates travel in both directions, can compact on the spot and work in narrow trenches and along walls. Plate width (35–70 cm) sets the pass width and productivity (m²/h).

Light and medium plates usually have 4–9 hp four-stroke petrol engines (Honda or Loncin type) that are easy to start and service. Heavy reversible models commonly use diesel engines (Hatz or Yanmar type), which are more economical, durable and built for long operation. See differences between two-stroke, four-stroke and diesel engines and engine displacement, power, torque and RPM: how to compare engine-powered equipment.

For asphalt compaction, choose a model with a water tank that wets the plate and stops hot mix from sticking. When laying paving slabs and blocks, use a polyurethane or rubber mat to protect the surface from chips and scratches.

Transport wheels, a lifting eye and a folding handle make it easier to load and move the plate around the site. A handle with anti-vibration mounts reduces vibration transmitted to the hands and fatigue during long work. See what is vibration level and what is an anti-vibration system.

Vibrating plates reach 95–108 dB, so wear hearing protection, safety footwear and gloves, plus a dust mask and glasses on dry ground. See how to choose hearing protection and how to choose personal protective equipment.

Do not work on slopes or near trench edges without control, keep your feet away from the plate and never run the engine indoors. On slopes, move straight up and down the incline, and stop the engine before moving the machine.

Regularly change the engine and exciter oil, clean the air filter and check belt tension and the rubber shock mounts. Choose a model whose belts, filters, shock mounts and mats are easy to find.
