AI Technical Summary

Problems solved by technology

[0003] During the fire fighting process, firefighters often need to climb on the roof of the fire truck to operate the fire cannon or access the roof equipment. The rear ladder of the existing fire truck is mostly fixed at the rear of the fire truck, and the distance between the bottom step and the ground is relatively high. , it is inconvenient to step directly on the back ladder

If the rear ladder is installed too low, it will affect the use and passage of fire trucks

The rear climbing ladder of some fire trucks is folded and fixed at the rear of the fire truck, and locked by the fixing buckle. This kind of rear climbing ladder is easy to shake after opening and closing, the installation and fixing are not firm enough, and the safety of use is not good enough.

In addition, there are multiple functional areas in the rear compartment of the fire truck, and the setting of the rear ladder will affect the normal use of these functional areas
