How a needle vibrator compacts concrete

The motor spins the needle, which vibrates and drives trapped air out of freshly poured concrete so it fills the formwork and wraps the reinforcement. Lower the needle vertically, hold it until air bubbles stop rising, then withdraw it slowly; insert it again about 1.5 times its radius of action away. Avoid touching the formwork or bending the hose sharply.

Where it is used

• Slabs, beams and columns on building sites
• Foundations and footings
• Precast work and small civil jobs

Frequently asked questions

Which should I choose — the RW-CV35-3 or the RW-CV35?

Choose the RW-CV35-3 for its 3 m reach and stronger 1100 W motor; the Ralli Wolf RW-CV35 (1.5 m hose, 850 W, 2 kg) is lighter for slabs and small pours.

How long is the needle on the RW-CV35-3?

The vibration rod (needle) is 35 mm diameter × 3 m long.

How long should the needle stay in one place?

Only until air bubbles stop rising and the surface turns glossy — usually a few seconds to about 15 seconds — then withdraw it slowly. Over-vibrating can make the heavy aggregate settle and bring water to the top.
