全锁刹车用一个踏板同时锁定轮子转动和转向头——手推车停在哪里就留在哪里，即使在坡道上或振动环境中也不移位。
RollMaster 转向头采用厂内机加工并淬硬的双层滚珠滚道；方向锁定型号可在全向转向与固定行进之间切换。
在刹车之间做选择是安全决策，不是功能清单：单轮刹车只锁轮子，脚轮仍可转向，在水平地面上没问题，但坡道停车、作业平台或任何供操作人员倚靠的设备都不适用。

| 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 |
测试与检验
回转力矩按批次测试
| 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 |
