• Enhances Concrete Bonding Through Controlled Surface Profiling: Features a 7-head scabbling configuration that effectively removes surface laitance, coatings, or weak layers from concrete, creating a uniformly roughened profile. This improves mechanical adhesion for overlays, sealers, or new concrete pours while maintaining structural integrity—ideal for floor renovation, bridge decks, or industrial slabs.
• Operates Efficiently Across Medium to High-Strength Concrete: Designed for consistent performance on concrete with compressive strengths ranging from C40 to C50, resulting a 3mm removal depth at a rate of 40–60 square meters per hour. The tungsten steel alloy chisel tips offer high wear resistance, ensuring sustained productivity without frequent replacements during large-scale resurfacing projects.
• Powered by Air Compressor Without Compromising Substrate Integrity: Utilizes pneumatic power supplied by an external air compressor (1600L/min required), reducing electrical hazards and preventing thermal or impact damage to the underlying concrete structure. This non-invasive method preserves the foundation’s load-bearing capacity while safely achieving desired surface texture. NOTE: buyers need to bring their own air compressor to ensure that the air pressure is 0.63Mpa.
• Compact and Modular Design for Flexible Job Site Mobility: Includes a hand-push frame with a working width of 29 cm and detachable components for easy transport and storage. The unit’s dimensions (29×49×127 cm) allow access to confined areas such as garages, stairwells, or commercial interiors, making it suitable for both indoor and outdoor concrete restoration tasks.
• Engineered for Operator Comfort During Extended Use: Balanced to reduce user fatigue, with vibration levels maintained at an average equivalent of 4.96 m/s². While noise output reaches 97 dB (requiring hearing protection per OSHA guidelines), the ergonomic push-handle layout enables precise control during prolonged operation on horizontal surfaces.
