When the stacker handles the goods, what is the vertical dimension of the pallet truss or the length of the girder called?

The term that specifically refers to the vertical dimension or the length of the girder in the context of a stacker handling goods is "span." In engineering and construction terminology, the span denotes the distance between two supports in a structure, and it relates to the overall capability and design of the lifting equipment.

When talking about the dimensions of a pallet truss or girder, the focus is on how it interacts with the load and its structural integrity. The span can significantly affect stability and load distribution, which is crucial for safe handling of goods in a warehouse or industrial environment.

In contrast, length, height, and width refer to different dimensions of an object, but they do not accurately capture the specific aspect of distance or reach in a structural context as the term "span" does, making it the precise term to describe the girder’s dimension in this scenario.
