01 — The problem

New people.
Little time.

Many new workers in parcel logistics are temp staff who are only there for a short time. From day one, they must load stable walls of parcels.

Today, experienced colleagues teach them on the job. That works – but every explanation takes an expert away from their own work.

  • Short stays

    Always someone new

    Temp staff come and go. The training starts again with every new person.

  • Unstable walls

    Walls can fall

    A wall that is not stable can fall when the container moves. Parcels get damaged, and unloading gets dangerous.

  • Lost time

    Experts are busy

    Each explanation on the floor takes an experienced colleague away from loading.

The idea Parcelademy teaches the five most important rules – short, visual and before the first shift.

02 — The rules

Five rules for
a stable wall

Learn them once. Use them in every container.

  1. T-pattern, not towers

    Don’t stack identical boxes straight on top of each other – towers fall. Place them staggered: each box rests centered across two boxes below.

    1 box on 2 boxes

    Left: three towers of boxes stacked straight, marked with a red cross. Right: a wall of boxes in a T-pattern, marked with a green check.

  2. The wall

    Stack the boxes in walls about 45 cm deep, from the floor to the ceiling. When a wall is almost finished, start the next one.

    Depth ≈ 45 cm · floor → ceiling

  3. Layer by layer

    Build one layer at a time, for example from right to left. Keep the layer at a similar height, so the next layer fits on top.

    Right → left · even height

  4. Straight front

    Seen from the front, the wall is flat. No box sticks out, and no box is pushed back.

  5. Heavy at the bottom

    Heavy boxes belong in the lower layers. Light boxes go on top – so nothing gets crushed and the wall stays stable.

03 — Checklist

The 5 rules
at a glance

Check your wall before you leave it. Tick each rule – or print this list and hang it up at the loading dock.

These are general tips based on practical experience. Always follow the safety rules and instructions of your employer.

In development

Practise in a
3D container

Soon you can load a container yourself: place boxes, build walls and get feedback on every rule – before your first real shift.

05 — About the project

Built by someone
who loads walls

Hi, I’m Leon M. I study Information Systems at TUM and work in parcel logistics myself.

Working in a parcel hub, I kept seeing the same thing: new colleagues – often temp staff on their very first day – had to learn how to build stable walls within minutes, while experienced loaders lost time explaining it again and again. Parcelademy turns that know-how into five visual rules anyone can learn before their first shift.

Roadmap Next up: an interactive 3D training built in Unity, a German version, and testing the rules with new colleagues to see whether they get up to speed faster.
