Description

technical field [0001] The invention belongs to the technical field of railway wagon car bodies, and more specifically relates to a flat-opening lower side door for a railway gondola. Background technique [0002] The gondola car is mainly used to transport bulk goods such as coal, ore, mining construction materials, timber, and steel, and can also be used to transport light-weight machinery and equipment. In my country's existing railway wagon composition, it accounts for more than 50% of the total number of wagons. The side door and the lower side door are the most frequently used body parts of the gondola car during manual or mechanical loading and unloading operations. The safety, corrosion resistance, and sealing of the door locks all affect the operation safety and operation and maintenance costs of the gondola car. [0003] The lower side door of the existing gondola car is opened upwards. When it is turned up, it needs to be connected to the hook set at a relatively...
