Advantages of Walk Behind Floor Grinder
- High-Temperature Durable Copper Motor
Equipped with a high-temperature durable copper motor, it resists burning even during long working hours, ensuring continuous high-efficiency operation, and provides stable torque for consistent grinding results across different floor surfaces. - Multi-Functional Chassis Design
Grinding discs and tools can be freely replaced and quickly adjusted to meet different construction needs, achieving various floor treatment effects, allowing operators to handle both rough concrete and smooth epoxy surfaces efficiently. - Independent Electrical Box with Indicator Lights
The independent power distribution system with indicator lights is simple to operate, runs stably, and allows the construction team to easily monitor equipment status, reducing downtime and facilitating safer operation during extended projects. - Protective Cover Close to the Floor
Prevents dust from spreading, reduces air pollution, and keeps the construction area clean, effectively improving on-site visibility while minimizing airborne particles and maintaining a healthier environment for workers. - Durable Dust Suction Pipe
Thick and durable, preventing pipe collapse or motor damage, ensuring the long-term stable operation of the dust extraction system, and maintaining continuous suction efficiency even during heavy-duty grinding tasks. - High-Strength Wheels
High load-bearing capacity, flexible steering, easy movement, and wear-resistant, improving operational convenience, allowing smooth navigation over uneven surfaces while reducing operator fatigue during long-duration grinding projects. - Dust Storage Cabinet
Efficiently collects dust, easy to clean, ensuring fan operation and prolonging equipment life, and helps maintain consistent grinding performance while reducing maintenance intervals and keeping the workspace tidy.

Practical Construction Cases
In actual projects, YG’s concrete grinding equipment has demonstrated outstanding construction efficiency and reliability. Case one involved resurfacing a factory floor over 5000㎡, where the team used concrete grinding equipment to quickly remove old coatings and level the surface. The work was completed in just three days, improving efficiency by approximately 50% compared to traditional manual grinding, providing a solid foundation for subsequent epoxy coating application. Case two was a commercial plaza epoxy floor pre-treatment project. The team selected a suitable YG model and combined it with the dust extraction system to quickly process 2000㎡ of floor, achieving a smooth surface, a clean working environment, and reduced labor costs.
