全鎖剎車以一個踏板同時鎖定輪子轉動與迴轉盤——推車精準停在停駐位置，即使在斜坡或振動環境下也不移位。
RollMaster 萬向盤採用廠內加工並硬化的雙滾珠軌道；方向鎖定版本可在自由萬向與直線行進之間切換。
在剎車之間做選擇是安全決策，不是功能清單：側剎車只鎖輪子，腳輪仍可迴轉，這在平地沒問題，但斜坡停駐、作業平台或任何人員倚靠的設備都不適用。

| 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
迴轉扭矩逐批次測試
| 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 |
