ROBENHOOD 28MM Vibrator Shaft RHV-28
The ROBENHOOD 28MM Vibrator Shaft RHV-28 is a professional concrete vibrator shaft designed to compact freshly poured concrete efficiently. Equipped with a 28mm vibrating needle, a 30cm needle length, and a 6-meter flexible shaft, it provides excellent maneuverability for narrow spaces and reinforced concrete work. Manufactured in Korea, this durable vibrator shaft helps eliminate trapped air, improve concrete density, and produce stronger, smoother, and longer-lasting concrete structures.
How to Use?
- Attach the vibrator shaft securely to a compatible concrete vibrator motor or drive unit.
- Start the motor and allow the vibrating needle to reach full operating speed.
- Insert the vibrating needle vertically into freshly poured concrete.
- Move the vibrator slowly between reinforcement bars and throughout the concrete pour.
- Withdraw the needle gradually to prevent air pockets from forming.
- After use, clean the shaft thoroughly and store it in a dry, protected location.
What Is the Purpose?
The ROBENHOOD RHV-28 is designed to remove trapped air bubbles and excess moisture from freshly poured concrete. Proper vibration increases concrete strength, improves bonding around reinforcement, minimizes honeycombing, and creates a smooth, durable finish for structural concrete work.
Key Features
- 28mm vibrating needle ideal for narrow and reinforced concrete sections.
- 30cm needle length for effective concrete consolidation.
- 6-meter flexible shaft provides excellent working reach.
- Removes trapped air for stronger and denser concrete.
- Flexible design allows easy operation around reinforcing steel.

Frequently Asked Questions
What is the ROBENHOOD RHV-28 Vibrator Shaft used for?
The ROBENHOOD RHV-28 is used to compact freshly poured concrete by removing trapped air, resulting in stronger, denser, and more durable concrete structures.
Why choose a 28mm vibrating needle?
The 28mm needle is ideal for narrow concrete sections and areas with closely spaced reinforcement where larger vibrator heads cannot easily reach.
Can this vibrator shaft be used for reinforced concrete?
Yes. It is specifically suited for reinforced concrete columns, beams, slabs, foundations, retaining walls, and other structural concrete applications.
Is the 6-meter shaft suitable for large projects?
Yes. The 6-meter flexible shaft provides excellent reach for deep pours and larger construction sites while maintaining operator convenience.
Why is concrete vibration important?
Concrete vibration removes trapped air and improves compaction, increasing structural strength, durability, and surface quality while reducing honeycombing and voids.
