Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting, and in particular relates to a large-flow upper structure for a small fire truck. Background Art

[0002] At present, there is no fast and effective fire-fighting equipment for application scenarios such as old urban areas, basement fire fighting, narrow streets, multi-loop roads in ancient building environments, and sharp turns. The main problem is that large fire trucks cannot enter, and small fire trucks do not have effective fire-fighting capabilities, and cannot effectively achieve the purpose of rescuing early, extinguishing small fires, and "arriving at the scene in 3 minutes". The upper structure of existing small fire trucks is usually equipped with a fire pump, which needs to borrow the power of the fire truck engine to work through the power take-off. Since the on-board engine of a small fire truck has low power, the power is not enough to drive a large-flow fire pump to work; at the same time, since the on-board engine is installed on the head of the fire truck, and the fire pump is located in the upper structure, it is difficult to take power, and the power take-off is large in size, occupying more space in the upper structure, resulting in insufficient space for setting up an independent member room.

[0003] Therefore, it is necessary to provide a large flow upper structure for small fire trucks. Utility Model Content
