Some places have high requirements on floor ground, not only requiring wear-resistant and durable, but also flat,such as production workshop,warehouse,storage centres,logistics centres,terminals. Because at these place,forklifts often carry goods back and forth,or heavy-loads pile up,the flat floor is more conducive to work safely,and forklift operation and cargo stocking will be more stable and avoid accidents.Due to the high requirement of wear-resitant for these places,the hardness of the floor will be relatively higher,which makes the floor grinding machine work more difficult.
