Engine companies that carry large quantities of ground ladders but lack a main aerial device are called what?

The term used for engine companies that carry significant amounts of ground ladders while not having a main aerial device is "Quad." Quads are specialized fire apparatus that combine features of both engine and aerial vehicles but typically do not include the aerial ladder component found in traditional aerial apparatus. Instead, they have an extended complement of ground ladders, which allows for versatile operational capabilities at fire scenes, particularly in situations where vertical access is required but not provided by an aerial device.

In contrast, a "Quint" is an apparatus that has both pump capabilities and an aerial device, combining the functions of a fire engine and ladder truck. The "Midipumper" refers to a specific type of pumper truck that is typically smaller than standard fire engines and has lower water capacity and pump output, which does not encompass the role of carrying a significant number of ladders. Therefore, the designation of "Quad" is the most fitting for this specific function.
