RollMaster 重型腳輪涵蓋 RM-Medium（150–500 kg）、RM-Heavy（500–1500 kg）與 RM-Extreme（1500 kg+）系列，輪徑 100 mm 至 300 mm。每一個支架在組裝前都經過焊接，並在動態測試機上完成載重測試。
典型應用：機械搬運滑撬、模具車、重型手推車、倉儲平台，以及必須在沒有保養窗口的情況下每個工作天都要滾動的設備。
規格
- 單顆腳輪承重 500–2000 kg（不平整地面安全考量，滿載時以 4 顆中的 3 顆計算）
- 焊接厚鋼板支架，鍍鋅或粉體塗裝表面處理
- 精密滾珠或滾子軸承，標準配備注油嘴
- 每個生產批次皆進行動態載重測試
表面處理
鍍鋅、鍍鉻、粉體塗裝
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
測試
輪子同心度與支架對位依內部 QC 標準；額定載重以 EN 12530 測試程序為基礎
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
