In 2022, Carlos Mendoza, procurement manager at a copper mine camp in the Peruvian Andes at 3,800 m elevation, asked us to supply two container cold rooms for the camp canteen's food storage. The goods would travel from our factory by sea to the Port of Callao, then over highway and mountain switchbacks to the mine. The complexity of that logistics chain is far beyond what most customers imagine.
Two incidents arose during the project. First, the mountain road had a transport height limit of only 4.2 m, and a standard flatbed carrying a 40HQ exceeded it. Second, the subcontractor's first crane was undersized; at the thin air of altitude and a large working radius, its effective capacity dropped sharply and nearly caused a tip-over. Only after we revised the loading plan and recalculated the crane tonnage did both units arrive safely.
A container cold room is not ordinary cargo. It has defined lifting points, a center of gravity, and specific securing requirements. A single misjudgment anywhere in the transport chain can damage the equipment or cause a safety incident. Using this real project, this guide sets out the complete plan from factory, sea freight, and inland transport to lifting and positioning.
| Size | External dimensions (L×W×H) | Empty weight | Lifting design weight* |
|---|---|---|---|
| 20FT container cold room | 6.06 m × 2.44 m × 2.59 m | ≈2.5–3.5 t | ≈5 t |
| 40HQ container cold room | 12.19 m × 2.44 m × 2.90 m | ≈4–5 t | ≈7 t |
*Including refrigeration unit, internal racking, and residual refrigerant; estimated at factory condition.
At a mine site in northern Chile, a subcontractor sent a 25-tonne crane to lift a 40HQ. On paper it seemed ample — the shell weighs under 5 tonnes. But the lift point was far from the road edge, giving an actual working radius of 9 m, at which that crane's rated capacity was only about 4.2 tonnes — below the unit's lifting weight once de-rated. The load visibly swung during the lift; only a quick stop by the ground crew prevented a worse outcome. A 50-tonne crane (about 12 t at 9 m radius) completed the job safely. Lesson: choose a crane by its rated capacity at the working radius, not by the maximum number on the nameplate.
A container cold room must be lifted with purpose-made rigging, never with wire rope simply wrapped around the shell:
A 40HQ shell is 2.90 m high and 2.44 m wide; on a trailer, total height typically reaches 4.0–4.3 m including the chassis. Before transport, every bridge and tunnel height limit and road width limit along the route must be verified. The Peru mine project adjusted its loading plan precisely because of a 4.2 m height limit.
When a project needs to ship components larger than the door opening (such as a large refrigeration unit or internal structural parts) together with the cold room, or when the customer assembles on site, an open-top container can be used: the roof is open, oversized parts are lowered in from above, then a waterproof tarpaulin is fitted and secured. An open-top box still has only four top corner castings as lifting points, so additional lashing is required after loading.
An island project in Sulawesi, Indonesia, required the cold room to travel by sea, transfer to a barge, and land on the island. The jetty had limited equipment and no large crane. We recommended forklift pockets pre-formed at the base: on a 20FT shell, two rectangular pockets on each side of the base, allowing a forklift to shift the unit short distances onto a roll-on barge. On the island, a 25-tonne truck crane lifted it from the barge onto the foundation. The multi-modal plan delivered a complete "port–barge–island" connection.
A Lagos distributor ordered four 20FT container cold rooms in one shipment. On deck, each unit was secured with four corner twist locks plus two ratchet straps per side, and the refrigeration units were wrapped in foam with transport brackets bolted to the compressor base. During a storm in the Gulf of Guinea the vessel rolled heavily; on arrival, all four units were intact, with no gasket distortion and no compressor displacement. The distributor noted that the previous shipment from a different supplier — secured with rope only — had arrived with two damaged door frames.
The hardest part of the Peru mine project was the final switchback road: tight curves, narrow lanes, strict height limits. We did three things:
Lifting into place is only the first step. Once positioned, the unit must be aligned and secured before use:
| Step | Requirement | Parameter |
|---|---|---|
| Level alignment | Four-corner levelness | Tolerance ≤5 mm/6 m |
| Positioning accuracy | Alignment with foundation/embedded parts | Deviation ≤10 mm |
| Anchor fixing | M16 anchor bolts | 8–12 per unit, tightened diagonally |
| Door re-check | Free operation, no jamming | Even door gap |
At an inland Saudi site, strong winds and unit displacement risk were a concern. We fixed each 40HQ with 10 M16 anchor bolts tightened diagonally into the concrete foundation, and added a windbreak wall on the windward side. Over three years of operation and repeated high-wind events, no unit moved and the doors stayed smooth throughout. Clearly, this "securing" step must not be skipped — especially in high-wind and seismic zones.
Two details are easy to overlook and expensive to fix. First, anchor bolts must be tightened diagonally — opposite corners in sequence — never in a circle, which can twist or distort the base and make the doors bind. Second, the door check happens after bolting, not before: anchoring can pull a shell slightly out of square, so the final door-swing test is the true confirmation that the installation is complete. We have seen units re-visited solely because a door was tested before the bolts were torqued to spec.
Back to Carlos's project. In the end we provided three supports:
Both units were positioned safely. In his acceptance email, Carlos wrote: "From the Port of Callao all the way up here to 3,800 m, you were the only supplier who laid out the entire logistics plan up front."
Flandcold is a source factory producing 10,000 container cold room units a year, holding 60+ refrigeration patents, and exporting through 3,600+ service points. For overseas engineering projects, we provide reinforced factory lifting points, transport reinforcement, a lifting guide manual, and remote video installation guidance, so equipment travels safely from the port to a high-altitude camp. If you are planning the logistics for a cross-border cold-chain project, our engineering team can help verify the lifting and transport parameters.
No. The top corner castings are designed for lifting; the base and side panels are not. Slings under the base crush the insulation, and slings around the sides deform the skin. Always lift from the four top corner castings.
For a unit weighing about 7 tonnes rigged, a 25-tonne crane is sufficient at a close radius, but check the load chart — at a 9 m radius even a 25-tonne crane may be marginal. When in doubt, specify a 50-tonne crane; the cost difference is small compared with the risk.
Request a route survey before shipping. Record every bridge height, tunnel clearance, and overhead line along the route, and plan the load height accordingly. If a limit cannot be met, an open-top or a partial-disassembly loading plan is the usual fix.
Our engineering team responds within 24 hours with crane tonnage calculations and logistics advice.
