Low-center-of-gravity casters: A "mobile base" as steady as a rock
Time：Oct 15,2025
I. What Are Low-Center-of-Gravity Casters?
The Low-Gravity Caster achieves a "ground-hugging" mechanical structure by lowering the relative height between the wheel frame and the wheel axle, thereby shifting the load's center of gravity downward. Typically paired with this design are features such as an expanded wheel surface, highly elastic tire material, and fully enclosed, dust-proof bearings—allowing for agile steering even when the caster operates at an extremely low center of gravity.
II. Three Core Advantages
1. Stability: With the center of gravity lowered by more than 30%, the rollover critical angle is improved by 2 to 3 times, allowing for "zero sway" even during high-speed push-and-pull maneuvers.
2. Province: Under the same load, the contact area of the wheel increases, reducing the pressure by 25%. As a result, both ground and tire wear decrease simultaneously, extending the average lifespan by 1.8 times.
3. Wide Range: Single-wheel static load capacity from 80 kg to 1.2 tons, offering full coverage. Customizable options include oil resistance, acid-alkali resistance, antistatic properties, and high-temperature tolerance, with corresponding models available for environments ranging from -40°C to 280°C.
III. Typical Application Scenarios
Industry: Intelligent warehousing AGVs, electric forklifts, and mold-handling carts—operating continuously 24 hours a day without missing a beat.
Medical: ICU monitoring beds, mobile imaging equipment stands—designed to operate silently at under 40 dB, ensuring patient comfort in the corridors.
Business: Supermarket "Silent Battle Carts," Airport Luggage Carts—capable of carrying up to 300 kg yet easily pushed with one hand, with zero inertia for effortless steering back to straight.
High-end equipment: Photovoltaic panel cleaning robots, stage lighting trusses—stable as tracks even on rugged outdoor terrain, with positioning accuracy of ±1 mm.
4. Selection Quick Reference Table
| Operating Condition Requirements | Recommended Series | Key Parameters | Optional Accessories |
| Unmanned Warehouse | LGW-PU-08 | 80 kg/wheel, Conductive PU, -10°C to 70°C | Anti-Entanglement Sealed Lid |
| Operating Room | LGM-TPR-06 | 60 kg/Wheel, Antibacterial TPR, Silent Bearings | Dual Pedal Full Brake |
| Cold Chain Logistics | LGN-PA-12 | 120 kg/wheel, Nylon Wheel Core, -40 ℃ to 80 ℃ | Stainless Steel Dust Cover |
V. Summary in one sentence
When "stability" becomes the primary driving force, low-center-of-gravity casters essentially equip your equipment with an "invisible track," ensuring that every move is safe, silent, and cost-effective.
