1. Product parameters: Name: Concrete processing vibration tool Weight: 5kg Product voltage: 110V/220V Battery voltage: 21V Battery capacity: 6.0Ah Rotation speed: 3000 6000rpm Power supply type: Brush motor Scraper size: 1m/1.2m/1.5m long, 8cm wide. 2. TRIANGULAR FIRM STRUCTURE The electric cordless vibration motor for concrete smoothing is comfortable to hold. The triangular fixed structure is firm, reliable, and more horizontal, ensuring stability during frequency vibrations and easy leveling. It provides deep vibration transmission to effectively remove air bubbles and compact the cement mud layer. 3. POWERFUL CONCRETE PULLER LATEST Equipped with a 6000mAh battery powered concrete finishing slat and a pure copper brushless frequency motor, it delivers up to 6000 rpm for uniform vibration across the entire surface, achieving results close to concrete smoothness. Ideal for shaping or wet smoothing to efficiently remove excess concrete. 4. RELIABLE VIBRATION MOTOR Features a frequency vibration motor made of pure copper. The concrete vibration screed has a sealed aluminum alloy housing, making it waterproof, dustproof, and faster at heat dissipation. Specially designed for concrete floors, cast panels, walkways, driveways, and other concrete work.
