Abstract
Description
Technical Field
[0001] The invention relates to the technical field of logistics transportation, and in particular to a self-propelled large-carriage vehicle ferrying device and a use method thereof. Background Art
[0002] A car ferry is a ferry specially used for transporting cars. It is characterized by having propellers and rudder equipment at both ends, and can be moored at the dock at both ends. The ship does not need to turn around when sailing, and cars do not need to reverse when getting on and off the ship, which shortens the ferrying time. The deck is straight from the beginning to the end, and is equipped with a hanger and a gangway to facilitate cars to drive on and off. The cab is generally located high on one side of the ship or above the central bridge to save deck area and facilitate observation. Large car ferries are mostly multi-deck and can carry hundreds of cars. Car ferries generally carry passengers or cargo.
[0003] However, due to the long and steep downhill slope of the wharf, a huge angle is formed between the ferry gangway and the downhill slope of the wharf. Large vehicles, especially heavy oversized vehicles, have long wheelbases and bodies, and some axles will be suspended in the air when passing through, causing the remaining axles to gather weight, crushing the vehicle deck and causing damage to the cargo. At the same time, due to the load limit of the cross-river bridge, large vehicles weighing more than 100 tons cannot pass, and crossing the river requires water and land transport, which has a long travel period and extremely high costs. Summary of the invention
