To enhance transport and storage, crates are handled in stacks. The stacks are unloaded into single crates for washing and packing.

Crates are stacked and destacked automatically by using stackers and destackers. The correct stacker and destacker models will be chosen with consideration for site and capacity. The same machine can both stack and destack.

Nekos stackers and destackers can be divided into two main models based on whether they stack from above or below. The model stacking from above is usually chosen when crates need to be transported to different floors or conveyors that are on a different level.

Depending on the model, stackers and destackers can handle between one and three stacks at a time.

The capacities of the models range from five hundred to three thousand crates per hour.
