How Loadwise Calculates Your Loading Plan
Loadwise treats cargo as rectangular packages and searches for arrangements inside the selected loading space. It checks modeled dimensions, payload and stacking rules, then shows loaded and remaining cargo. It does not certify that a shipment is safe or legally compliant.
1. Dimensions and volume
Enter the outside packaged dimensions, including the pallet and any overhang. Length units and weight units are independent. CBM is length × width × height in metres; total CBM multiplies this by quantity. Empty space between pieces is not part of cargo CBM.
For example, a 120 × 100 × 110 cm crate is 1.320 m³. Ten such crates total 13.200 m³. At 320 kg each, they weigh 3,200 kg. Try the CBM calculator.
2. Placement and rotation
The planner tries multiple arrangements and cargo orderings. Allowed base rotation swaps length and width by 90 degrees; it does not tip a crate onto its side. An arrangement must respect the selected loading space and configured clearance. The search is a practical estimate and is not guaranteed to find the best possible layout.
3. Door fit and equipment
Closed-equipment door checks compare upright cargo dimensions with the modeled opening. They do not simulate forklift movement, turning paths or loading ramps. Equipment dimensions are presets, not measurements of your assigned unit. Verify actual dimensions and payload with the carrier.
4. Stacking
Single-stack cargo allows nothing on top. Double-stack cargo permits up to two layers when support, height and top-load checks allow it. Advanced settings include a maximum top weight and a same-cargo-type stacking rule. A blank top-load rating uses the pallet’s own weight as a planning cap; it is not proof of packaging strength.
5. Weight and axle estimates
The selected cargo payload limits the total modeled cargo weight. For supported semi-trailer presets, the illustrative axle model assumes empty weights of 11,000 lb on the steer axle and 12,000 lb on each tandem. Its two 34,000 lb tandem limits leave a combined modeled cargo allowance of 44,000 lb.
These are model assumptions, not the measured weights of your tractor and trailer. Cargo position changes the estimated distribution; actual scale readings, axle spacing, equipment ratings and applicable route rules must determine a real loading decision. Remaining axle capacity is not automatically additional cargo capacity.
6. Reading the result
- All pieces loaded: the model placed the requested quantities; review any separate warnings.
- Pieces not loaded: review size, payload, stacking and clearance constraints or compare another vehicle.
- Review required: read the specific warning before using the plan.
Blocking and restraint drawings are schematic suggestions. They do not calculate restraint strength, tie-down count or an engineered securing design.
Worked examples
Use the 53 ft trailer guide for the 26-pallet input example, or the container guide for the ten-crate example. These are illustrative inputs, not records of completed shipments. Run the inputs in the planner and review the resulting layout and warnings.
