How it works and why it is used
In a trailer swap, the tractor unit drops a tank trailer at a site — where it stays to be loaded, unloaded or cleaned — and hooks up another one to keep working, without the driver waiting. It is a variant of drop-and-hook that separates the tractor's cycle from the tank's cycle, cuts driver idle time and increases tractor utilisation. It usually requires more tank trailers than tractor units and is common in liquid bulk and chemicals.
What you need to keep track of
Every job must keep the traceability of its specific tank: the semi-trailer's registration on the control document, its load status and its cleaning record (the ECD). Without that control, swapping creates confusion about what each tank carried and when it was cleaned.
Giormo records swaps with the traceability of each tank — its load, its cleaning and its documents — not just the tractor's. See it.
