Home / Robotic truck loading
The robot empties the trailer. People stay on the dock.
A telescopic belt boom reaches the full length of a 13.6 m trailer. A robot head on its nose sees the wall of cases with 3D cameras and takes them with a vacuum gripper, top layer first, straight onto the belt. Nobody works inside the trailer while it runs. At the next door, a 6-pallet pack drives in and out on its own.

Two docks, two kinds of load.
Dock 1 unloads loose cases with a robot head on a telescopic boom. Dock 2 loads and unloads whole pallets with no forklift. The interactive model shows our earlier dock 1 concept, a mobile robot inside the trailer feeding an expandable conveyor; the design in the main image puts the robot head on the boom.

The 3D model runs faster than real life so the whole cycle fits in about half a minute.
Dock 1 · boom and robot head (D1)
- 1. Reach in. The telescopic boom extends over the dock leveller into the trailer, up to 13.5 m. A light curtain at the door keeps people out while it runs.
- 2. See the wall. 3D cameras on the robot head map every case face.
- 3. Top layer first. The arm picks the highest case, so nothing falls.
- 4. Grip. Vacuum cups hold the case by its face and let go on the boom belt.
- 5. Ride out. The case rides the boom belt into the building, one case at a time, with gaps.
- 6. Next slice. When a slice is clear, the boom extends further. Beyond about 5.4 m a nose bogie supports the head on the trailer floor.
Dock 2 · automatic pallet loading
- 1. Form the pack. Six EUR pallets arrive one by one on a floor-level chain conveyor: 3 across, 2 deep.
- 2. Drive in. The chain and the trailer's moving floor run together. The whole pack goes in at once.
- 3. Unload the same way. The moving floor brings a pack out onto the chain, and pallets leave one by one.
- 4. No forklift. No one drives in or out of the trailer.
Better than a person on a boom.
A plain boom conveyor still needs a person in the trailer lifting every case. Our robot head does the lifting from the end of the boom.
- No heavy lifting. Trailer unloading is hot, heavy, repeated work. The robot takes it.
- Steady rate. The same pace on every shift. The market leaders quote 800 to 1,600 cases an hour.
- Gaps built in. Cases leave one at a time with space between them, so the sorter and scanner read every one.
- One case size rule. The model uses a 600 × 400 mm case footprint. Tote storage receives totes, not loose cases; contents must fit the tote after decant.
- Safety design. Area scanners, emergency stops and guarding are proposed. Protective fields, stopping performance and access need project-specific validation.
- Data. Every case is counted and checked against the delivery note in our WCS.
Easy to fix. A plan B at every dock.
Recovery options aim to reduce dock downtime. Availability depends on the fault, remaining equipment and approved working method.
- Quick-swap gripper. The cup plate comes off with 2 clamps. Cups are a push-fit spare.
- Mains powered. The boom and robot head run from the dock supply, so there are no batteries to charge between trailers.
- Swap the head. The robot head is a module on the boom nose. A spare head can be fitted while the faulty one goes to the bench.
- Manual fallback. An independent conveyor may support a planned manual fallback, subject to isolation of the robot and an approved handling method.
- Predict built in. Our sensors watch drive motors, vacuum pumps and bearings for early wear.
- Pallet dock fallback. Forklift fallback requires a compatible trailer and an approved, segregated loading method.

Three things we need to know.
We size the robots and pallet docks around your trailers and loads.
Trailers
Lengths, heights, and which ones have a moving floor.
Loads
Loose cases or pallets, case sizes and weights, trailers per day.
Link
Where the cases go next: sorter, tote storage or a pick area.
Truck loading questions.
Is it for sale?
Not yet. It is in 3D design. We can plan it into your dock layout now.
What about mixed, messy loads?
The cameras see each case. Odd items are flagged and set aside for a person. Our target is cases with a flat face up to 23 kg.
Does it need a special trailer?
No. The boom reaches into a normal 13.6 m trailer. Trailer floors vary, so we confirm wheel loads for the nose bogie with the haulier. A moving-floor trailer is only needed for the 6-pallet pack dock.
Can people work nearby?
Nearby work requires assessed separation and validated protective measures. A painted line alone is not a safeguard; protective fields and stopping distances must be verified for the task.
Does it link to the rest of the site?
Yes. Cases are planned to feed the sorter or AMRs; suitable items are placed into standard totes at decant before tote storage. WCS coordination remains in development.
