This category includes Hamilton ground support caster configurations built around semi-pneumatic tires for durability and reduced maintenance. Select the series based on required capacity, terrain, and equipment type.
| Series | Capacity (Up to) | Best Fit |
|---|---|---|
| Ground Support | 7500 | 4,200 lb | General ground support moves where semi-pneumatic durability is needed without dual-wheel requirements. |
| Dual-Whl Ground Support | 7,200 lb | Higher loads and improved stability; dual-wheel designs reduce floor loading and improve tracking on uneven terrain. |
| Cush-N-Tuf | 4000 | 550 lb | Lighter-duty equipment moves where cushioning and floor/terrain forgiveness matter more than extreme capacity. |
| Cush-N-Flex | 8000 | 800 lb | Mid-duty applications needing added compliance over rough surfaces while staying compact and controllable. |
Semi-pneumatic tires provide compliance over uneven surfaces without the same air-loss and maintenance profile of fully pneumatic tires.
No. The 7,200 lb rating applies to specific Dual-Whl Ground Support builds and is model-dependent. Verify the rating on the selected listing.
Dual-wheel designs are typically preferred for higher loads, stability, and reduced floor loading—especially on uneven surfaces.
These calculators apply to any caster application—even if you’re browsing a different category. Use them to estimate load rating per caster, select wheel material, and estimate push/pull force. Expand any tool for full analysis + a share-ready spec line.
