Pallet Library
The Pallet Library is your catalog of available pallet types. LOP comes pre-loaded with eight standard pallet types used in international logistics. You can also create custom pallet types to match your specific warehouse or customer requirements.
Standard Pallet Types
LOP includes the following standard pallet types out of the box:
| Code | Name | Dimensions (L x W) | Platform Height | Max Stack Height | Max Payload |
|---|---|---|---|---|---|
| EUR | Euro Pallet | 1200 x 800 mm | 144 mm | 1800 mm | 1500 kg |
| EUR2 | Euro Pallet 2 | 1200 x 1000 mm | 144 mm | 1800 mm | 1500 kg |
| GMA | GMA (North America) | 1219 x 1016 mm | 150 mm | 1800 mm | 1134 kg |
| ASIA | Asia Standard | 1100 x 1100 mm | 150 mm | 1800 mm | 1500 kg |
| AUS | Australian Standard | 1165 x 1165 mm | 150 mm | 1800 mm | 1500 kg |
| UK | UK Standard | 1200 x 1000 mm | 150 mm | 1800 mm | 1250 kg |
| HALF | Half Pallet | 800 x 600 mm | 144 mm | 1200 mm | 500 kg |
| QTR | Quarter Pallet | 600 x 400 mm | 144 mm | 1000 mm | 250 kg |
Each pallet type also defines an overhang allowance — the maximum distance an item can extend beyond the pallet edge (typically 0–50 mm).
Pallet Properties
Every pallet type in the library has the following properties:
- Code — short identifier (e.g., EUR, GMA)
- Name — descriptive label
- Platform Length and Width — the usable surface area in mm
- Platform Height — the height of the pallet structure itself (boards + stringers), in mm
- Max Stack Height — the maximum total height of items stacked on the pallet, measured from the pallet surface
- Max Payload — maximum total weight of items on the pallet, in kg
- Overhang Allowance — how far items may extend past the pallet edge, in mm
- Stackable — whether loaded pallets can be stacked on top of each other in the container
- Max Stack Weight — if stackable, the maximum weight that can be placed on top of this loaded pallet
Selecting Active Pallets
Before you can use a pallet type in the Palletize Panel or Palletize All, you need to mark it as active:
- Open Pallet Library from the left sidebar
- Check the box on the card for each pallet type you want to use
Your active pallet selection is saved to your account and persists across sessions and devices. You can change it at any time.
Only active pallet types appear in the Palletize Panel dropdown and are considered by Palletize All. If you do not see a pallet type in the editor, check that it is activated in the Pallet Library.
Custom Pallets
To create a custom pallet type:
- Open Pallet Library from the left sidebar
- Click + Create Custom Pallet (top right)
- Enter the pallet's code, name, dimensions, weight limits, and other properties
- Click Save
Custom pallets appear alongside the standard types in the library and can be activated and used in exactly the same way.
Racks and Other Custom Carriers
Some cargo does not sit on a pallet — it sits in a frame. A steel rack with four tiers, an A-frame for glass, a stillage, a wheeled trolley: these are carriers with a shape of their own, and LOP handles them by letting a custom pallet type carry a 3D body.
Upload the carrier's CAD file to the pallet type and LOP treats it as what it is: a real object with tiers, posts and gaps that your cargo goes between.
Adding a body
- Open Pallet Library and find your custom pallet type (standard types such as EUR or GMA cannot carry a body — their shape is a flat platform, which LOP already models exactly)
- Click Upload 3D body (STEP) on the card
- Pick the file. STEP (
.step,.stp) is placed as modelled. Mesh files (.stl,.obj,.ply) are read in millimetres with Y up — if your exporter used different units or a Z-up axis, convert before uploading - Processing runs in the background, exactly as it does for a library item. The card shows a 3D body badge when the body is ready
Once the body is ready it is drawn everywhere a pallet is drawn: the library card, the editor viewport, and the palletize preview.
What the body decides
Uploading a body changes what LOP knows about the carrier:
- The footprint and the height come from the body itself — its platform height becomes 0 (the body is the structure) and its maximum stack height becomes the body's own height
- The levels are read off the body's shape. LOP finds the surfaces inside the frame that are wide enough to rest cargo on, and those become the tiers you load in Racks in a Plan
- Collision is checked against the real form, not a box, so cargo can sit between the posts and under the next tier instead of being refused
You still type the numbers LOP cannot read off a mesh: the tare weight (the empty carrier's own weight), the maximum payload, the overhang allowance, and the stack count — how many identical loaded carriers may stand on top of each other.
Re-uploading a body replaces it everywhere. A carrier's 3D body is stored once per pallet type, not once per plan, so replacing the file changes the shape used by every plan that already holds one of these carriers. Upload a corrected body deliberately, and re-open older plans to check them.
A rack's tare weight is never counted as cargo. It is part of the carrier, so it is excluded from every fill and payload figure you see on the rack itself, and included in the total weight the container carries.
