Calculate transport-unit capacity

Start with usable internal transport-unit dimensions, then add the external dimensions, quantity, unit weight, loading sequence, and permitted rotations for each packaged load.

Live example loaded - edit any value to calculate your own transport load.

20 palletized units at 1200 x 800 x 1100 mm and 900 kg each are evaluated in a 12032 x 2352 x 2395 mm internal envelope with 26500 kg maximum payload. The visible result comes from the real KolliPack Transport engine.

One shared implementation. This public calculator and standalone Transport Container Selection use the same request context, form, engine service, result partials, Three.js viewer, catalogue access rules, and PDF export path. Packaging Flow uses the same service and shared prefixed Transport components.

How to use this tool
Estimate how many products, cartons, pallets, or mixed items can be loaded into a transport unit.
1. Define the transport unit

Use the internal loading dimensions in mm. For trucks, trailers, sea containers, or cargo compartments, enter the usable loading space, not the outside vehicle size.

2. Add the items to load

Each row can represent a product, carton, pallet, crate, or another load unit. Dimensions are in mm; weight is in kg.

3. Set rotations and stackability

Use R1/R2/R3 to control allowed orientations. Clear Stackable when other load units must not be placed on top of that product.

4. Review dimensional and payload limits

The result checks both available loading space and max payload. A practical validation step is still needed for load securing, axle load, stacking limits, and local transport rules.

Transport unit
Use manual internal loading dimensions or select a transport unit from the packaging catalogue.
Space Evenly: Creates strong product blocks and distributes cargo using the Space Evenly loading strategy.
Load Front-to-Back: Creates strong product blocks and fills the load progressively from the back toward the doors.
Space Evenly – Mixed Cargo Infill: Uses Space Evenly as the main loading strategy and fills bounded side residuals with compatible remaining products. Explicit sequence groups are respected.
Load Front-to-Back – Mixed Cargo Infill: Uses Load Front-to-Back as the main strategy and fills compatible side residuals while preserving the active loading frontier. Explicit sequence groups are respected.
Leave blank if you only want dimensional loading validation.
Use the empty transport unit weight if you want a gross loaded weight summary.
Items to load
Add products, cartons, pallets, crates, or mixed load units manually or from catalogue. Stackable means other load units may be placed on top.

Calculator outputs

Read quantity, volume, weight, and remaining space

The result keeps geometric use and payload use separate so you can see which entered restriction limits the load.

Loaded and unplaced quantity

Placed units come directly from the engine placement list. Unplaced units are requested units that could not be assigned within the current geometry, rotation, sequence, and payload settings.

Volumetric use

Volume utilization compares the volume of placed load units with the usable internal transport-unit volume. Occupied and residual dimensions help describe the calculated envelope.

Weight and payload

Loaded weight is cargo weight. Payload utilization compares cargo weight with the entered maximum payload. Optional tare is added separately to report gross loaded weight.

Input guide

Three steps to build a transport loading estimate

1

Select the transport unit

Enter usable internal dimensions manually or choose a transport container, trailer, pallet, crate, or other load unit from a public catalogue when one is available.

2

Describe the packaged loads

Add one or more product, carton, pallet, or crate rows. Enter external dimensions, required quantity or Max qty, unit weight, sequence, and only physically permitted rotations.

3

Inspect and validate

Compare quantity, volume and payload metrics, inspect the same placements from Loading View, Opposite Side and Top View, then export the same three fixed orientations through the shared PDF path.

Rotations and views

Understand loading alternatives

R1, R2, and R3 control the supported orthogonal orientation groups used by the shared packing heuristic. The current Transport tool produces one deterministic placement for the entered sequence and restrictions; the camera buttons inspect that same placement rather than presenting separate optimization claims.

Max qty

For a checked row, the service searches the maximum quantity the real packing heuristic can place while respecting fixed rows and payload. It does not use a template-side capacity formula.

Rotation restrictions

Disable orientations that are not physically allowed because of stability, fragility, upright handling, liquids, stack strength, or access requirements.

One scene, several cameras

The interactive renderer uses one serialized placement list. Its open rear doors remain at the established end and are displayed at approximately 135 degrees.

Engineering scope

What the transport estimate does not certify

This is geometric and entered-payload decision support. It does not certify real loading access or route legality.

Access and sequence

Confirm door aperture, forklift access, practical loading and unloading order, dunnage, clearances, and handling equipment with the actual unit.

Stability and securement

Validate center of gravity, axle loads, floor loading, stacking strength, blocking, bracing, lashing, airflow, and load securing separately.

Catalogue dimensions

Public catalogue entries are runtime data, not universal specifications. Confirm usable dimensions, tare, payload, manufacturer data, and local rules for the selected equipment.

Frequently asked questions

Container loading calculator FAQ

What does a container loading calculator calculate?
It estimates how many rectangular load units the selected transport unit can place, then reports unplaced quantity, volume use, loaded weight, payload use, occupied dimensions, and remaining dimensions.
Which dimensions should I enter?
Use usable internal dimensions for the transport unit and external length, width, and height for each packaged product, carton, pallet, crate, or other load unit.
What does Max qty do?
Max qty asks the shared Transport engine to find the largest quantity the current packing heuristic can load while respecting the other entered rows, rotations, available space, and payload.
Does the calculator check container payload?
Yes. Enter a maximum payload and load-unit weight to compare cargo weight with that payload. Tare is reported separately and is added only to the gross loaded weight summary.
Does the result replace a physical and legal transport check?
No. Confirm door-aperture access, loading sequence, load securing, stacking strength, axle and centre-of-gravity limits, airflow, dangerous-goods rules, and route-specific legal requirements separately.
