Concrete Foor Grinder 800-4A
800-4A is a self-propelled floor grinding and polishing machine, which integrates heavy pressure, reliable operability and flexible operation. It is one of Xingyi's best-selling floor grinding and polishing equipment. The grinding machine has a four-head planetary counter-rotating gear drive system. Compared with a three-head gear, it is beneficial to reduce the deflection force generated by the machine during grinding. It can better control the machine, make the grinding more uniform, and realize the innovation of low maintenance gear. This machine can easily work on Max. And it can be used for ramp grinding, with a slope of about 20 angles, suitable for parking lots. Its self-propelled system is friendly to workers, and a certain speed is better. The machine can walk for 30 minutes without power and is ideal for transportation. We can charge it with an additional power source (220v), or charge it by ourselves while working. Equipped with a 3-speed additional counterweight iron, which can be used to maximize the grinding pressure during work and reduce the pressure when the machine is lifted. An ideal grinder suitable for easy grinding.
