A vestibule consisting of (17) is presented.

In this conventional pruning device method, cut tree branches fall on sidewalks or roads, causing inconvenience to pedestrians or vehicles, as well as temporary traffic congestion as vehicles equipped with joint lifts and collection vehicles occupy part of the lane together. In addition to causing problems, such as requiring a lot of manpower and time for pruning. In particular, as the number of civil complaints related to street trees is increasing year by year, it is necessary to drastically improve road maintenance work.

Therefore, the present invention was invented to solve the above problems, and not only can cut and prune branches in a desired street tree shape without a person directly climbing the tree, but also directly prunes by concentrating the cut branches so that they do not fall to the ground. It is an object of the present invention to provide a pruning device for a street tree pruning vehicle that can be loaded into a vehicle, thereby reducing the time and cost required for pruning and not interfering with traffic.
