Cold store equipment rarely fails on the first day. It fails in month eight, when a roller has gone hard, a seal has drawn moisture and a scanner window has frosted over. This chassis was specified around that timeline rather than around a datasheet headline.
| Challenge | Our answer |
|---|---|
| Rollers stiffen and crack | Low temperature polyurethane grade that keeps rebound at minus 25 degrees |
| Moisture enters the hub | Double lip seals, low temperature grease, sealed bearing cavity |
| Laser window fogs at air curtains | Heated scanner windows with anti condensation coating |
| Battery capacity drops | Low temperature cells plus pack heating during charging breaks |
| Ice builds under the frame | Raised frame floor and open drainage path, washdown friendly fittings |
| Wheel size | 350mm (14 in) |
| Payload | 1500kg |
| Operating range | minus 25 to 40 degrees C |
| Frame envelope | 1600 × 1100 × 320mm |
| Roller compound | Cold grade polyurethane, 16 per wheel |
| Hub sealing | Double lip seal with low temperature grease |
| Rated speed | 1.0 m/s |
| Battery | 48V 50Ah low temperature lithium |
| Ingress rating | IP54 with heated sensor windows |
| Sensor heating | Thermostatic, 12V, auto controlled |
Every component that needs attention during a shift sits behind a single latch panel, so a technician can swap a wheel or clear a fault without emptying the compartment. Roller sets are sold as pairs, which keeps spare stock small and predictable.
