[0001] The present invention relates to the technical field of road obstacle clearing equipment, and in particular to a side forklift mechanism and a side obstacle clearing vehicle equipped with the side forklift mechanism. Background Art

[0002] Road tow trucks are essential supporting equipment in modern transportation. In order to deal with the tow work on complex roads, some existing tow trucks are equipped with side forklift mechanisms on their sides.

[0003] However, the existing side-mounted forklift mechanism structure is relatively simple, such as a side-mounted tow truck disclosed in CN106218485A, and a drive assembly of a side-mounted tow truck disclosed in CN221162423U. The forklift mechanism used therein can only realize the lifting, translation and telescopic movement of the telescopic fork, and the spacing between the two telescopic forks cannot be adjusted for different vehicle models. In order to target longer vehicle models, two sets of forklift mechanisms are provided, and the lifting position is on the tire of the rescued vehicle, which is not the lifting position designed by the automobile manufacturer, and disputes may easily occur due to improper rescue. Therefore, the scope of application of this type of side-mounted forklift mechanism is relatively small. At the same time, in order to realize the lifting and translation of the telescopic fork, its lifting mechanism and translation mechanism will occupy a large space, which is very inconvenient during transportation.
