How do you ship a heavy part without dealing with freight?
A 60 lb pump. A replacement motor. A control unit that needs to reach a technician. A heavy part doesn’t automatically have to become a freight shipment.
Kübox gives heavier, fragile and valuable items a reusable structural container designed for parcel handling. Add suitable internal protection, check the finished size and weight, and use the parcel service that fits your shipment.
For eligible shipments, that means keeping the familiar process: pack it, create a label and arrange pickup.
Why deal with freight if you can ship it as a parcel?
Freight can mean identifying a freight class, arranging pallet handling and finding out whether the recipient has a loading dock, forklift or needs a liftgate.
Those arrangements make sense when the shipment needs them. For a smaller replacement part, they can add work at both ends.
The first question is simple: can this part be properly protected inside a package that meets the chosen parcel service’s requirements?
Keep the familiar process
For eligible shipments, book through your chosen parcel carrier using the package’s outside dimensions, packed weight and required service.
Simplify receiving
A parcel-compatible shipment may avoid the pallet, dock and unloading arrangements associated with freight. Check access and handling needs for the actual recipient.
Make the return easier
Plan the container and internal packing for both trips. Give the recipient a clear way to return the old part using the same packaging.
Example: shipping a 60 lb pump by parcel.
Suppose you need to send a replacement pump weighing 60 lb (27.2 kg), and you want the old pump returned in the same packaging.
Here is how to work through the decision. This is an illustrative example, not a packing specification for a particular pump.
Start with the complete pump.
Measure the housing, shaft, mounting feet, fittings and any other projections. Identify where the pump can safely be supported and which parts must be protected from loads.
In this example, the complete pump measures 20 × 12 × 8 in. (50.8 × 30.5 × 20.3 cm), including its projections.
Allow room for the protection.
An illustrative 2 in. (5.08 cm) allowance on each side gives a protected envelope of at least 24 × 16 × 12 in. (61.0 × 40.6 × 30.5 cm). The actual space required depends on the cushioning, supports and restraint selected for the pump.
A shaft does not automatically rule out parcel shipping. Support appropriate housing or mounting surfaces, control movement and keep handling loads away from the shaft.
Compare a Kübox configuration.
The standard Trunk size below has enough listed interior space for that illustrative protected envelope. Fit is the starting point; the load and internal packing still need to be suitable for the application.

| Measurement | Imperial | Metric |
|---|---|---|
| Pump weight | 60 lb | 27.2 kg |
| Complete pump dimensions | 20 × 12 × 8 in. | 50.8 × 30.5 × 20.3 cm |
| Illustrative protected envelope | 24 × 16 × 12 in. | 61.0 × 40.6 × 30.5 cm |
| Selected Trunk interior | 36 × 20 × 15 in. | 91.4 × 50.8 × 38.1 cm |
| Listed assembled exterior | 39 × 23 × 18 in. | 99.1 × 58.4 × 45.7 cm |
| Length plus girth | 121 in. | 307.3 cm |
| Estimated dimensional weight | 117 lb using divisor 139 | 53 kg using divisor 5,000 |
DIM estimates are calculated separately from the original exterior dimensions and rounded up to whole pounds or kilograms. The two results are not direct conversions. Carrier measurement, rounding and account rules may differ.
Weigh the complete package and check the service.
The pump’s 60 lb weight is not the shipping weight. Add the Kübox, internal supports, cushioning, containment and any accessories. Weigh and measure the closed package.
Compare those finished measurements with the selected carrier’s service limits and the allowable load for the Kübox configuration. For an international shipment, also check destination requirements and customs documentation.
The same approach applies to motors, control units and more.
Start with the same questions: how much does it weigh, where can it be supported, what can be damaged, and how will it be restrained? Then adapt the packing to the item.

| Equipment | What needs attention | Packing considerations |
|---|---|---|
| Pumps | Shafts, fittings, mounting feet, uneven weight and possible residual fluids. | Support suitable housing or mounting surfaces. Protect projections, control movement and provide compatible leak containment where needed. |
| Electric motors | Shafts, fans, terminal boxes, mounting feet and concentrated weight. | Distribute loads through suitable supports. Protect the shaft and attachments from bearing the weight during handling. |
| Control units and electronics | Connectors, displays, circuit assemblies, shock sensitivity and static sensitivity. | Use suitable cushioning and static protection where required. Protect controls and connectors from pressure and impact. |
| Valves, actuators and gearboxes | Dense housings, levers, fittings, exposed edges and uneven centers of gravity. | Support robust surfaces, protect projections and prevent the load from migrating through softer packing materials. |
| Instruments and test equipment | Calibration, delicate assemblies, probes, screens and environmental sensitivity. | Follow the equipment manufacturer’s transport guidance. Select cushioning and environmental protection for the actual sensitivity. |
| Avionics and field-service equipment | Connectors, sensitive assemblies, identification and repeated shipping cycles. | Use repeatable packing, suitable protective materials and clear inspection and return instructions. |
Internal supports do not have to be wood. Engineered corrugated build-ups, laminated paperboard, honeycomb, foam and other suitable materials can form part of the packing design.
If the design uses bolts, clamps or other fasteners, evaluate the attachment points, bearing area and load path. The right arrangement depends on the part and handling conditions.
Need the old part back? Plan both trips.
The replacement part is only half the job when a technician needs to return a failed pump, motor or control unit. Make the return process clear before the first package leaves.
- Check that both parts fit. Account for differences in shafts, fittings, accessories and the condition of the return core.
- Use packing that can be recreated. Make supports and inserts easy to identify and put back in the correct position.
- Provide short, illustrated instructions. Show where the part sits, which pieces must be retained and how to close the Kübox.
- Include return supplies. Provide the return label or booking instructions, plus replacement containment materials where required.
- Inspect before reuse. Check the Kübox and its internal packing for damage, contamination or missing components before the return trip.
Protection backed by transit testing.
Kübox combines heavy-duty corrugated panels, laminated structural profiles, reinforced corners, reusable hubs, locking pins and mechanical fasteners.
Kübox has received passing results under transportation test protocols including ISTA 1A, ISTA 3A, ISTA 3E and 6-FEDEX-A.
Those results provide evidence about the configurations tested. They do not mean every part, container size or internal packing arrangement has been tested together. The complete packaging system must suit the shipment.
Questions about shipping heavy parts.
Can I ship a 60 lb pump through a parcel carrier?
A 60 lb pump may qualify for parcel shipping when the complete packed shipment meets the selected service’s size, weight, contents and packaging requirements. The packing must support the pump, protect vulnerable areas and control movement during handling.
Does a shaft make a pump or motor unsuitable for Kübox?
No. A shaft affects the internal protection design. Support suitable housing or mounting surfaces, provide clearance and keep handling loads away from the shaft. Include its full length when measuring the part.
Can I use the same packing method for a control unit?
The same planning principles apply, but the protective design may differ. A control unit may need static protection, cushioning for sensitive electronics and clearance around connectors or displays.
Does the part have to be square or evenly balanced?
No. Irregular geometry and an uneven center of gravity influence where the part is supported and how it is restrained. They do not automatically rule out Kübox.
Does Kübox replace internal cushioning and restraint?
Kübox provides the structural outer container. Internal cushioning, supports and restraint protect the contents from shock, movement and contact with vulnerable surfaces. Select both together.
Can I send the replacement and return the old part in the same Kübox?
Yes, when the container and internal packing are suitable for both parts and remain fit for reuse. Include repacking instructions and check the return part for residual fluids or other transport restrictions.
Can this work for international shipments?
Kübox can be considered for international parcel applications when the finished shipment meets the selected service and destination requirements. Check customs documentation, contents restrictions, packaging requirements and any special rules for the equipment.
Is parcel always cheaper than freight?
No. Compare actual quotes for the finished shipment. Include packaging, dimensional weight, additional services and any surcharges, as well as preparation and receiving requirements.
When should the part stay in freight?
Use an appropriate freight service when the finished shipment exceeds parcel limits or requires pallet handling, controlled orientation, special equipment or other conditions the parcel service does not provide. Kübox Freight Cube or a custom configuration may suit an appropriate freight application.
Do I have to buy shipping through Kübox?
You can evaluate Kübox as the protective container for a shipment booked through your chosen carrier. Confirm the finished package’s acceptance and service requirements with that carrier.
Tell us what needs to move.
Send the part’s dimensions, weight and a few photographs. Include the origin, destination, required transit time and whether the old part needs to come back.
We can help you evaluate the Kübox size and the packing considerations for your application.
