A standard truck will work in a cold store for a while, then fail early. Cold store specification changes the hydraulic oil, seals, battery arrangement, electrical protection and sometimes the steel grade.
| Standard | Cold store | |
|---|---|---|
| Hydraulic oil | Standard | Low pour point, below −40 °C |
| Seals | Standard rubber | Low-temperature compound |
| Battery | Standard | Heated compartment or lithium, charged outside |
| Electricals | Standard | Higher IP rating, anti-condensation |
| Steel | Standard | Low-temperature grade where required |
| Operator area | — | Heated handles, anti-fog lighting |
| Cost | Baseline | Typically 15–30% higher |
Hydraulic oil thickens, so lift and tilt slow down and the pump works harder. Seals harden and start to leak. Battery capacity drops sharply below freezing. These appear within months, not years.
Charging inside a freezer damages the battery and wastes energy. Most cold stores charge at ambient temperature and swap packs — which means the truck needs a swap-friendly battery arrangement.
Trucks moving between frozen and ambient zones collect condensation on cold metal. Without anti-condensation measures this reaches the electricals and causes intermittent faults.
