Description

Technical Field

[0001] The utility model relates to the technical field of lifting frame structures, and more specifically, to a lifting frame structure of a sweeping vehicle. Background Art

[0002] The sweeper is an integrated garbage cleaning vehicle that combines sweeping and vacuuming. It has the advantages of high work efficiency, low cleaning cost, good cleaning effect, high safety performance and high economic return rate. It has been widely used in road cleaning work in large, medium and small cities.

[0003] At present, when sweeping vehicles are dumping garbage, most of them are done by manually unloading the garbage bins on the vehicle body, and then pushing the garbage bins to dump the garbage to the designated garbage collection area, which is time-consuming and labor-intensive. Most of the existing lifting frame structures cannot lift garbage bins of different sizes as needed, which is extremely inconvenient to use. Utility Model Content
