AI Technical Summary

Technical Problem

The limited length of the tailgate of existing transport vehicles makes it difficult to load and unload heavy goods such as fire rescue equipment, especially when the equipment is large in size and weight.

Method used

The system uses a hydraulic drive assembly to drive the tailgate and movable floor to work together to form a long ramp. The tailgate is flipped and moved by a hydraulic cylinder, and combined with the extension and retraction of the movable floor, it achieves semi-automatic loading and unloading of goods.

Benefits of technology

It enables the formation of longer ramps, reduces the difficulty of loading and unloading heavier goods, improves loading and unloading efficiency, and is suitable for loading and unloading operations of goods with large volume and weight.
