A total lock brake locks both the wheel rotation and the swivel head with one pedal — the cart stays exactly where it was parked, even on slopes or under vibration.
RollMaster swivel heads use double-ball raceways machined and hardened in-house; directional lock versions convert between full swivel and fixed travel.
Choosing between brakes is a safety decision, not a feature list: a side brake locks only the wheel and the castor can still pivot, which is fine on level floors but not for slope parking, work platforms or anything an operator leans on.

Oberflächen
Zinc, chrome, powder coat, stainless
| 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 |
Prüfung
Swivel torque tested per batch
| 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 |
