Jingkun GX90S | Command the Entire Operation Under a Giant Grinding Width
Jingkun GX90S | Command the Entire Operation Under a Giant Grinding Width
22kW Pure Copper Motor × 30kW Vector Inverter × 900mm Ultra-Wide Grinding Path — Redefining Floor Construction Efficiency
The challenge in floor grinding has never been about "can it grind," but about how to balance efficiency, flatness, and unexpected on-site situations in mega-projects. The Jingkun GX90S large remote-control floor grinder, powered by robust engineering and forward-looking intelligent control, gives you the strength to command the entire job with complete confidence.
Hardcore Power Heart, Fearless in Any Working Condition
The GX90S is powered by a 22kW high-power pure copper motor, delivering deep, surging strength that easily handles heavy continuous operations such as high-strength concrete, old epoxy removal, and stone grinding. Paired with a 30kW vector inverter, it achieves wide-range stepless speed regulation. Whether for aggressive rough grinding or delicate polishing, it finds the most precise speed match — no motor burnout, no arc pulling, and the equipment runs as steady as a rock.
900mm Giant-Screen Grinding, Efficiency Multiplied
A single 900mm grinding width lays a giant canvas across the floor. The area covered in one pass far exceeds that of conventional machines. In large-area workshops, underground parking garages, and similar environments, construction efficiency is doubled or even multiplied, drastically shortening project timelines. Combined with a precisely tuned overall balance system, the machine stays flat and firmly hugs the floor even with such a wide grinding path — no chatter marks.
12-Disc Planetary System, Delicate Grinding Like Weaving
The grinding head adopts a planetary disc design, armed with 12 grinding discs working in formation. The discs revolve around the main axis while simultaneously spinning at high speed, creating intricate and dense grinding trajectories. This effectively eliminates the circular swirl marks caused by single-rotation patterns. The resulting floor surface is uniformly even, laying the perfect foundation for densification and polishing. Both flatness and finesse surpass the limits of traditional machines.
Smart Remote Control, Away from Dust and Fatigue
During high-intensity construction, the operator no longer needs to follow the machine step by step. The GX90S comes standard with a remote-control operating system — forward, reverse, steering, and speed adjustment are all easily done at your fingertips. The operator can stand in a clean area away from noise and dust, overlooking the entire operation. This dramatically reduces physical exertion and makes the construction process safer and more ergonomic.
Power-Loss Endurance Black Technology — A Step Ahead of Accidents
Jobsite environments are complex. If a sudden power outage causes the grinding discs to freeze on the floor, it can leave irreparable deep scratches. The Jingkun GX90S embeds a Power-Loss Endurance Protection System — in the event of an unexpected power failure, the built-in energy storage unit responds instantly, automatically raising the grinding head and maintaining drive to safely move the equipment off the working surface. This completely eliminates the construction nightmare of "power failure ruining the floor," protecting your hard-won super-flat concrete.

From my experience working on large-scale floor grinding projects, controlling efficiency and achieving a perfectly flat surface can be very challenging, especially when covering extensive areas like underground parking lots or manufacturing facilities. The Jingkun GX90S impresses with its remarkable 900mm grinding width, which significantly reduces the number of passes needed, effectively cutting down project time. What truly differentiates this machine is its 12-disc planetary system. During operations, I noticed this design eliminates common swirl marks that often result from traditional single-rotation grinders. The intricate overlapping grinding patterns produce a smooth, uniform finish that greatly improves the quality of concrete surfaces, which is crucial for subsequent polishing and densification phases. Safety and operator comfort also matter a lot on job sites. The GX90S’s remote control feature allowed me to navigate the machine from a clean, dust-free area. This not only reduced fatigue but also enhanced my control precision. It alleviated the usual strain from following the machine closely while minimizing exposure to noise and dust—a big advantage during long shifts. The power-loss endurance technology is a game changer. I recall once working in a site with spotty power supply, where sudden outages could have scarred the concrete permanently. The GX90S’s built-in energy storage instantly lifted the grinding head and moved the machine off the floor, protecting the surface from deep scratches. This kind of proactive protection saves costly rework and preserves the integrity of the floor. Overall, the GX90S combines robust power, intelligent control, and innovative safety features. For anyone involved in demanding floor grinding tasks seeking to enhance productivity, surface quality, and jobsite safety, this machine presents an excellent solution that respects the complexities of mega-project environments.
