LD1800

  • Positioning: Extra-wide direct-drive grinding that eliminates wave patterns at the source for high-precision, dead-flat floors.
  • Applications: Airport terminals, high-speed rail stations, major convention centers, automated logistics warehouses, precision manufacturing plants, and high-end mixed-use developments — large, high-precision floor projects.
  • Advantages:

    ▪ Extra-wide one-piece disc: A large-diameter, one-piece disc maximizes coverage per pass and eliminates the wavy overlap marks that multi-disc planetary heads leave behind — flat and consistent across the whole slab.

    ▪ Heavy-disc concentration on high spots: The weight and rigid structure of the large one-piece disc naturally concentrate cutting pressure on elevated areas — high spots get cut down first while low areas are protected, delivering high-precision leveling.

    ▪ High-power grinding: Custom-tuned motors deliver consistent, robust power for hard concrete and deep material removal — solving the edge wave and power drop issues common with older grinders.

  • Positioning: Purpose-built for large infrastructure and high-precision industrial floors. It turns mirror-flat from an aspiration into standard practice — the workhorse for quality and productivity on big floor jobs.
