4) Stacker Cranes

Lastly, stacker cranes are similar to bridge cranes. However, instead of using hoists, it uses a mast with forks or platform to handle unit loads. Stacker cranes are considered “fork trucks on a rail” due to its look.

These cranes are usually used for storing and retrieving unit loads in storage racks, especially in high-rise applications in which the racks are more than 50 feet high.

The crane can be either controlled remotely or by an operator in a cab on the mast.

Below are some pictures of stacker cranes:
