The trailers or trucks to transport the crop from the field.

Trucks for transporting onions or potatoes from the field.

In general, after a mechanised harvest, an onion or potato loader is used to fill one of these two types of trucks:

Tipper truck.

Truck with rear discharge conveyor.

Tipper trucks

Big and small tipper trucks unload into a special unloader, which does the following:

1. Receives the produce from the truck in a controlled manner.
2. Pre-cleans the produce, separating clods, stones, leaves, etc. from the onions or potatoes.
3. Creates an adjustable flow of produce, to fill the storage facility in a controlled manner.

For more details on these bulk unloaders for onions, potatoes and many other products, see: Bulk unloader.

Trucks with discharge conveyors.

This type of truck comes in many shapes and sizes, but they all have the same machine inside, which protects the produce from damage and ensures a smooth, uniform unloading. For more information about the details of a truck with rear discharge conveyor, read this: Trucks with rear discharge conveyor.
