A reach stacker is a machine that is used to load and unload containers from ships at the port. The reach stacker driver controls the machine by manipulating levers that move the forks and knuckle boom, which are attached to a platform that extends out over the ship's container hatch. Reach stackers are primarily used to change cargo loads, but they can also be used to move cargo around on land or in deep water ports where cranes cannot be used. The reach stacker driver is responsible for moving cargo using reach stackers that are built by different manufacturers, each with their own unique designs and features. In order to be an efficient and safe driver, it's important that you have knowledge of how reach stackers work, in addition to knowing how to use them properly.
