Mechanical Vibrators 230 V

230V Mechanical Vibrators from Enar and Wacker Neuson — How the Shaft-Driven Design Works

A 230V mechanical vibrator (an external-drive poker vibrator) compacts concrete with high-frequency vibration. The motor stands outside the concrete and connects to the poker head with a drive shaft — a flexible shaft that turns an eccentric weight inside the poker. The resulting vibration drives trapped air bubbles out of the mix.

At NORWIT.PL we offer 230V mechanical vibrators primarily from Enar, Wacker Neuson and Beton Trowel, complemented by Altrad Belle. Enar equipment is also available on the Enar brand page. This category belongs to the wider group of 230V concrete vibrators, alongside built-in-converter sets and 42V / 200Hz vibrators.

Types of Mechanical Vibrator Components — Poker Head, Drive Shaft, Motor and Complete Set

Unlike an electric vibrator with a fixed motor built into the poker head, a 230V mechanical vibrator is made of three separate parts — motor, drive shaft and poker head — each sold on its own or as a ready-made set.

The split design lets you replace only the worn part — poker head, drive shaft or motor — instead of the whole set, cutting running costs compared with an electric vibrator that needs a full poker replacement after a failure. Drive units are also offered by Husqvarna.

Choosing Poker Diameter and Shaft Length for the Job

Poker diameter is matched to the thickness of the element being cast. Too small a poker lengthens compaction time, while too large a one can damage the reinforcement mesh.

Shaft length depends on how far the poker head needs to reach. A 3–4 m shaft is enough for strip footings, while for excavations deeper than 2 m a 5–6 m shaft or longer works better.

230V Mechanical Vibrator vs Electric Vibrator — Key Differences

Both types compact concrete with a vibrating poker head; they differ in where the motor sits.

A mechanical vibrator suits continuous work and single-part replacement — on large sites and foundation pours. An electric vibrator is lighter to carry between elements, but a motor failure means replacing the whole poker head.

Servicing and Replacing Worn Parts

The shaft inside the drive sleeve wears fastest — it works under continuous flexing and friction, so it needs greasing roughly every 20–40 hours of use. The eccentric-weight bearings inside the poker head wear too, especially with sharp aggregate in the mix. Because poker heads, drive shafts and motors are sold separately, a repair means ordering the worn part, not the whole poker head. Related parts: poker heads, drive shafts and vibrator motors.

Frequently Asked Questions About 230V Mechanical Vibrators

Why Buy a 230V Mechanical Vibrator at NORWIT.PL

We specialise in concrete-compaction equipment: our 230V mechanical vibrator range holds primarily Enar, Wacker Neuson and Beton Trowel, complemented by Altrad Belle. We advise on poker and shaft selection; every component — poker head, drive shaft or motor — can be bought separately or as a complete set. For damp conditions we recommend 42V / 200Hz vibrators, and for built-in-converter sets, vibrators with a built-in 230V converter. The full overview is in 230V concrete vibrators.
