Jingkun GX90S | Under the Vast Grinding Swath, Total Intelligent Command

22kW all‑copper motor × 30kW vector inverter × 900mm ultra‑wide grinding path – redefining floor construction efficiency.

The real challenge in floor grinding has never been “can’t grind” – it’s how to balance efficiency, flatness, and the ability to handle unexpected situations on mega‑scale projects. The Jingkun GX90S large remote‑controlled floor grinder gives you hardcore power and forward‑looking intelligence, so you can command the entire site with complete composure.

Hardcore Power Heart – Fearless in Any Condition

The GX90S is driven by a 22kW high‑power all‑copper motor that delivers deep, surging output, easily handling continuous heavy‑duty operations such as high‑strength concrete grinding, old epoxy removal, and stone polishing. Paired with a 30kW vector inverter, it offers a wide stepless speed range. Whether you need aggressive surface opening or delicate polishing, you can always dial in the precise RPM – no motor burnout, no arcing, and rock‑steady reliability.

900mm Wide‑Swath Grinding – Efficiency Multiplied

A single pass with a 900mm grinding width spreads a giant “curtain” across the floor, covering far more area per pass than conventional machines. In large workshops, underground garages, and similar spaces, construction efficiency soars and project timelines are cut dramatically. Combined with a finely balanced overall machine design, it stays firmly grounded even during wide‑pass operations, leaving no chatter marks behind.

12‑Segment Planetary Head – Flawless, Fabric‑Like Finish

The grinding head uses a planetary design with an array of 12 segments. Each segment revolves around the main disk while also spinning rapidly on its own axis, creating a dense and complex motion pattern that effectively eliminates the circular swirl marks left by single‑rotation designs. The finished surface is uniformly smooth, providing a perfect foundation for sealing and polishing – with flatness and fineness that surpass the limits of traditional machines.

Smart Remote Control – Away from Dust and Fatigue

During intense jobs, operators no longer have to walk right behind the machine. The GX90S comes standard with a remote‑control system that puts forward, reverse, steering, and speed adjustment literally at your fingertips. You can stand in a clean area with a full view of the worksite, away from the noise and dust – greatly reducing physical strain and making the job safer and more ergonomic.

Power‑Outage Ride‑Through – One Calm Step Ahead of the Unexpected

Jobsite conditions can be unpredictable. A sudden power failure that leaves the grinding head frozen on the floor can cause deep, costly scratches that are difficult to repair. The Jingkun GX90S is equipped with a power‑outage ride‑through protection system: when an unexpected blackout occurs, the built‑in energy storage unit responds instantly, automatically lifting the grinding head and maintaining drive power to safely move the machine off the work surface. This fundamentally eliminates the nightmare of blackout‑induced floor damage – safeguarding your hard‑earned super‑flat results.
