Concrete vibrator MAR-POL 79492 — 35 mm head diameter, 2 m shaft

The concrete vibrator MAR-POL 79492 is a handheld tool with a 35 mm poker head diameter and a 2 m flexible shaft designed for targeted consolidation of fresh concrete. It is intended to remove entrapped air, improve particle packing and achieve uniform compaction in narrow formwork, repair zones and small pours. The compact head size and long, flexible shaft allow access to confined areas and localized vibration during finishing and patching jobs.

Advantages

The 35 mm head provides focused vibration for narrow cavities and repair spots while minimizing disturbance to surrounding formwork. The 2 m flexible shaft offers reach and maneuverability for working from the edge of a slab or within small molds. The handheld design supports portable on-site use and short-duration tasks without the need for larger machinery.

Suitable for

• Small concrete pours and patch repairs
• Narrow formwork, precast joints and column pockets
• Finishing works where localized compaction is required
• Site maintenance and concrete remediation tasks

When it may not be suitable

This vibrator is intended for localized and small to medium concrete tasks rather than large-scale industrial pours. For large slabs, foundations or continuous high-volume casting, a larger-diameter poker or integrated vibration system is typically more efficient and faster. Operators should also consider that prolonged use may require breaks to avoid motor overheating and fatigue when used manually for extended periods.

Key specifications

• Poker head diameter: 35 mm
• Shaft length: 2 m, flexible
• Handheld, portable design for manual operation
• Suitable for targeted, localized concrete consolidation

How to use

Insert the poker head vertically into fresh concrete at regular intervals, keeping the shaft steady to allow the head to vibrate freely. Hold the unit so the vibrator head reaches the required depth, withdraw slowly to allow trapped air to escape and stop when the mortar surface levels. For continuous areas, overlap insertion points to achieve uniform compaction. Follow the manufacturer's instructions for connection, safe handling and any required personal protective equipment.

What to consider before purchase

• Match the 35 mm head diameter to the size of the formwork and aggregate size
• Confirm the 2 m shaft length is sufficient to reach work areas from the operator position
• Assess expected workload to determine if a handheld unit meets productivity needs
• Check power source compatibility and local safety requirements for portable vibrators

Usage recommendations

Use short insertion cycles and avoid forcing the poker against formwork. Maintain a consistent insertion pattern across the surface to prevent over-consolidation in one area. Allow the motor to cool during extended use and inspect the flexible shaft regularly for wear or damage.
