Introduction of various types of containers and their sizes (forget the source of this article, the internal dimensions are correct, and the internal dimensions are for reference only. It is possible that a small number of containers produced in the past meet the internal dimensions. I'd like to know the authoritative figures of container internal dimensions now. Please see the introduction of container size (1)/ Ant Knight/blog/item/b4c9312a/3f224395243rd12d.html). The 20-foot and 40-foot containers we usually see are called dry goods containers, also called grocery containers, and some people call them it. This kind of container is used to transport groceries without temperature control. It has a wide range of uses, including 20-foot and 40-foot containers, and the heightened 40-foot container is also a dry container. The structural feature of this container is that it is usually closed. Generally, there is a door at one end or one side, and there are certain devices to reinforce the goods in the box. When using this box, it should be clean and watertight. In order to make full use of the container capacity, it is necessary to properly package the loaded goods. Now let's introduce the external dimensions and internal areas of these three commonly used dry goods containers in detail: 20-foot container: the external dimensions are 6.1m× 2.44m× 2.59m (20 ft× 8 ft× 8 ft6 in); (1 ft = 12 inch = 30.48cm) The internal volume is 5.69m× 2.13m× 2.18m ... Generally, this container is loaded with heavier goods, and the gross weight of the goods is generally not allowed to exceed17. 40-foot container: overall dimensions are12.2m× 2.44m× 2.59m (40ft× 8ft× 8ft.6ft); The internal volume is11.8m× 2.13m× 2.18m ... This kind of container generally contains light foam goods, and the gross weight of the goods is generally not allowed to exceed 22 tons. It can hold goods with a volume of about 54 cubic meters and 40 feet. Overall dimensions are12.2m× 2.44m× 2.9m (40ft× 8ft× 9ft 6 in). The internal volume is11.8m× 2.13m× 2.72m. This container is also equipped with light foam goods, and the gross weight of the goods is not allowed to exceed 22 tons, and the capacity of the goods is about 68 cubic meters. In addition to these three common containers, other types of containers are generally called special containers. If the goods need special containers, you should book the shipping space with the shipping company when booking, because the shipping company can't have such special containers in every port. Now we will introduce the special containers for you one by one: open-top containers, which are characterized by convenient disassembly and installation of the top of the containers. There are two kinds of box tops: hard top and soft top. The hard top is made of thin steel plate and is loaded and unloaded by lifting machinery. Soft top is generally made of canvas, plastic cloth or plastic-coated cloth, which can be rolled to one end when it is opened. This container is suitable for loading large goods and heavy goods, such as steel, wood and machinery, especially fragile heavy goods such as glass plates. The goods are hoisted into the box from the top by crane, which is not easy to damage the goods and is convenient to fix in the box. Ventilated container Ventilated container is characterized by several windows for ventilation on its side wall or top wall, which is suitable for transporting groceries with certain ventilation and moisture-proof requirements such as fruits and vegetables. If ventilation window is closed, it can also be used as a grocery box. Platform-based container This container is characterized by no top wall and side walls, even the end wall has been removed, and only has a bottom plate and four corner posts. This container can be loaded and unloaded from front, back, left, right and above, and is suitable for loading long and heavy pieces, such as heavy machinery, steel, wood and steel ingots. The gantry container is not waterproof, and the wet goods cannot be shipped. If it must be transported, it must be covered and sealed with canvas. Platform container This container is more simplified than the platform container, and only the bottom plate is reserved. Mainly used for loading and unloading long and heavy goods. Such as heavy machinery and equipment, steel, etc. The length and width of the platform are the same as the bottom size of international standard containers, and the same fasteners and lifting devices as other containers can be used. The adoption of this kind of container breaks the past concept that containers must have a certain volume. Refrigerated container Refrigerated container, also known as freezer, is a kind of insulated container, which mainly transports frozen food and can keep the set low temperature. It is specially designed for transporting fish, shrimp, meat, fresh fruits, vegetables and other foods. At present, there are basically two kinds of refrigerated containers used in the world: one is called mechanical refrigerated container with freezer inside; The other container has no freezer, only heat insulation equipment. The end wall of the container is provided with an air inlet and an air outlet. After the box is installed in the cabin, the ship's freezer provides cold air, which is called clutch refrigerated container (also called external refrigerated container). As the name implies, tank container is specially designed for transporting liquid goods, such as alcohol, gasoline and chemicals. It consists of a tank and a frame, wherein the tank is used for loading liquid, and the frame is used for supporting and fixing the tank. The outer wall of the tank is insulated by thermal insulation materials, and the inner wall is generally polished to avoid liquid remaining on the wall. In order to reduce the viscosity of the liquid, there is also a heater at the lower part of the tank, and the temperature inside the tank can be observed through the thermometer installed at the upper part. In order to facilitate loading and unloading, the top of the tank is provided with a loading port and the bottom is provided with a discharge valve. When loading, the liquid enters from the top loading port of the tank, and flows out from the discharge port when unloading, and can also be sucked out from the top loading port with a straw. Car container This container is specially used to transport small cars. Its structural feature is that there is no side wall, only a frame and a box bottom. In order to prevent the car from sliding in the box, the bottom of the box is also specially equipped with binding equipment and anti-skid steel plates. Most car containers are designed with two floors, which can hold many cars. Fence container or live animal container This is a container specially used for transporting live animals such as chickens, ducks, pigs and cows. In order to avoid sunlight, the top and side walls of animal containers are made of FRP. In addition, in order to ensure the fresh air in the box, windows made of aluminum wire mesh are used on the side and end faces to strengthen ventilation. There are cleaning ports and drainage ports under the side walls, and there are sliding doors that move up and down, which can clean up the garbage. The side wall of the box body is also provided with a feed inlet. Animal containers on ships are generally installed on the deck, because the air on the deck is ventilated and convenient for cleaning and care. Clothes containers are also called hangers. Characterized in that a plurality of cross bars are installed on the upper side beam in the container, a plurality of belt buckles, nylon buckles or ropes are hung on each cross bar, and the hooks on the clothes hangers are directly hung on the buckles or ropes. This way of clothing loading belongs to unpackaged transportation, which not only saves packaging materials and packaging costs, but also saves 20-foot containers.
