[0002] The semi-trailer towing seat is a load-bearing component used to tow the semi-trailer body. It belongs to the front chassis component. It has the function of engaging and locking with the towing pin of the semi-trailer body through a locking mechanism, and is a device that can transmit horizontal and vertical forces between the front and the body. For semi-trailers, the towing seat is crucial.
