Description

Technical Field

[0001] The utility model relates to the field of vehicle modification, in particular to a workbench for modifying sanitation vehicles. Background Art

[0002] When sanitation vehicle manufacturers produce sanitation vehicles, they generally design and modify based on existing truck chassis. Since the height of the truck chassis itself is relatively high, after adding a water tank and a garbage bin on this basis, its height is higher than that of an adult. When workshop workers perform modification operations on the upper part of the vehicle (such as installing components, grinding welds, etc.), they usually need to rely on ladders or climb onto the upper part of the vehicle to perform modification operations. During the climbing process, workers are prone to danger. At the same time, it also affects the working efficiency of workers. Summary of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide a workbench for modifying sanitation vehicles. The utility model adopts the following technical solutions:
