Standalone desktop app for palletised upright-cargo loading. Extract and run — no installation needed.

Overview

SmartPacker U3 is designed for loading palletised cargo where all units must remain upright in the container. It combines multi-SKU flexibility (like T3) with an upright-only orientation constraint — essential for fragile, top-heavy, or liquid cargo.

U3 supports:

  • Multiple cargo types (multi-SKU)
  • Multiple pallet sizes — both standard and non-standard
  • Automated optimisation and manual editing
  • Pallet-by-pallet 3D visualisation
Demo A — Overview: automated loading calculation and 3D result

Pallet Setup

Define one or more pallet sizes to use in the plan. U3 supports both standard sizes (e.g. EUR, GMA) and custom non-standard dimensions. Set the Length, Width, and Height for each pallet type.

Defining Cargo

Add each cargo type with its dimensions and name. U3 enforces upright placement — cargo is placed with the designated top face always pointing up, regardless of how it is arranged horizontally.

You can edit cargo names and parameters at any time and immediately see the loading pattern update.

Quantity Panel

Like T3, U3 features an interactive cargo-quantity panel with red/green indicators:

  • Green — current cargo mix fits within the container
  • Red — exceeds available space

Adjust quantities per cargo type to find the maximum loading combination.

Manual Editing

Beyond automated calculation, U3 supports manual editing — you can directly adjust the placement of individual units in the 2D editing view. This is useful when you need to accommodate real-world constraints like access gaps, weight distribution, or loading order.

Demo B — Manual editing in 2D view, 3D rotation, and pallet-by-pallet visualisation

2D & 3D Views

U3 offers both a 2D editing view (top-down, for precise placement) and a 3D rotation view (for inspection). You can switch between views at any time. The 3D view supports pallet-by-pallet breakdown — step through each pallet layer to verify the loading sequence.

Demo C — Editing cargo name/parameters and watching the pattern update in real time

Tips

  • Use the automated mode first to get a baseline, then refine with manual editing
  • Step through pallets in 3D to verify loading order before dispatch
  • For cargo that can be rotated freely (not upright-only), use SmartPacker T3
  • For single carton types, use SmartPacker T1
