The volume is 86 cubic meters \x0d\ container size \x0d\ If you have the opportunity to pass by or enter the container yard in the port, the mountains of containers and container trailers will definitely surprise you. Colorful painted boxes, as well as the logos and patterns of various shipping companies sprayed on the boxes, are even more dazzling. You may sigh that there are so many kinds of containers. However, what you usually see most is the general 20-foot and 40-foot standard containers and some 40-foot heightening containers. In fact, containers are a huge family, and you may not have seen many special containers. Now we will introduce this container family to you. \x0d\ The 20-foot and 40-foot containers we usually see are called dry container, also called grocery container, and some people call them containers. 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. \x0d\ Now let's introduce the external dimensions and internal volumes of these three kinds of commonly used dry goods containers in detail: \x0d\ 20-foot container: 20-foot container for short (20GP)\x0d\ The external dimensions are 6.1m× 2.44m× 2.59m (20ft× 8ft6in); \x0d\ The internal volume is 5.69m× 2.13m× 2.18m. \x0d\ This container is generally loaded with heavy goods, and the gross weight of the goods is generally not allowed to exceed 17.5 tons, and the volume of the goods it can hold is about 24-26 cubic meters. 20-foot folding platform container: the internal dimension is 5.946 m x 2.2 16 m x 2.233m, and the distribution gross weight is 27. 1 ton. \x0d\ 40-foot container: a 40-foot container (abbreviated as \x0d), with overall dimensions of12.2m× 2.44m× 2.59m (40ft× 8ft× 8ft.6ft); \x0d\ The internal volume is11.8m× 2.13m× 2.18m ... \ x0d \ This kind of container generally contains light foam goods, and the gross weight of the goods is generally not allowed to exceed 22 tons, which can hold about 54 cubic meters of goods \ x0d. \x0d\ The internal volume is11.8m× 2.13m× 2.72m ... \ x0d \ 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 cargo volume can be about 68 cubic meters. \x0d\ 40-foot folding platform container: the internal dimension is12.080m x 2.126m x 2.043m, and the delivery gross weight is 29.2 tons. \x0d\ 45-foot-high container: the internal volume is 13.58m x 2.34m x 2.70m, the gross weight of cargo distribution is generally 29 tons, and the volume is 86 cubic meters \x0d\ Except for these three common containers, other types of containers are generally called special containers. If the goods need special containers, it is generally necessary to book the shipping space with the shipping company when booking the space, because it is impossible for the shipping company to book the space in every container. Now we will introduce the special containers for you one by one: \x0d\ OpenTopContainer)\x0d\ \ This container is characterized by easy disassembly and installation at the top of the container. 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. \x0d\ 20-foot open-top cabinet: the internal volume is 5.89 m X2.32 m X2.3 1 m, the gross power distribution weight is 20 tons, and the volume is 3 1.5 m3. \ x0d \ 40ft open-top cabinet: the internal volume is12.01m x 2.33m x 2.66. Ventilated container \ x0d \ Ventilated container is characterized by a plurality of 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. \ x0d \ platformbased container) \ x0d \ x0d This container is characterized by no top wall and side wall, even the end wall is removed, only a bottom plate and four corner columns. \x0d\ The container can be loaded and unloaded from front, back, left and 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. \x0d\ Plat-formContainer This container is more simplified than the gantry 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. \x0d\ 20-foot flat-bottomed container: the internal area is 5.85m x 2.23m x 2. 15m, the gross container weight is 23t, and the volume is 28m3. \x0d\ 40ft flat-bottomed container: The internal area is12.05m x 2.1.96m. Refrigerated container) \x0d\ \ Refrigerated container, also known as freezer, is an 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). \x0d\ Tankcontainer \ x0d \ As the name implies, this 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. \x0d\ CarCon-container)\ x0d \ This container is specially used for transporting 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. \x0d\ Animal container \ x0d \ This container is 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. \x0d\ clothes container \ x0d \ is also called clothes rack. \x0d\ This container is characterized in that a plurality of cross bars are installed on the upper side beam in the container, and 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 belt buckles or ropes. This kind of clothing loading mode belongs to unpackaged transportation, which not only saves packaging materials and packaging costs, but also reduces labor and improves the transportation quality of clothing. \x0d\ SolidBulkContainer This container is used to transport powdery or granular goods, such as soybeans, rice and various feeds. There are 2-3 loading ports at the top of this container and unloading ports at the lower part of the door. Using this container to transport bulk cargo, on the one hand, improves the loading and unloading efficiency, on the other hand, improves the freight quality and reduces the harm of dust to human body and environment. \x0d\ 20-foot HeavyContainer)\x0d\ \ This container is specially used for loading small and heavy goods, such as cast iron products, hardware products and ceramic tiles. Its size is standard 20 feet. Because the general standard 20-foot container can only carry 17.5 tons of goods, it can't meet the requirements of some goods, so the carrier provides a 20-foot container. \x0d\ If you are an exporter, after you know the families of these containers, you should know what kind of containers are suitable for your export goods. If your goods are suitable for ordinary dry goods containers, after you know the internal dimensions of standard containers, you can design the length, width and height of your packing box to be proportional to the length, width and height of the container, so that you can waste less container capacity and load more goods when loading. Of course, container goods must not be overweight, because overweight is very dangerous and all countries have strict controls. Many countries have made laws and regulations to punish overweight people. \x0d\ classification by use: \x0d\ containers are generally divided into \x0d\ (1) general dry goods containers, also called dry goods containers, which are used to transport groceries without temperature control. It is widely used. According to the statistics of 1983, 85% of the 3 million containers in the world are groceries, about 2.54 million. This container is usually closed with a door at one end or one side. This container is usually used to transport cultural goods, chemical products, electronic machinery, handicrafts, medicines, daily necessities, textiles and instrument parts. This is the most commonly used container. All kinds of solid bulk, granular or powdery goods that are not affected by temperature changes can be shipped in this container. \x0d\ (2) Keep thermostatic containers. They are used to transport goods that need to be refrigerated or kept warm. Containers whose walls are insulated by materials with low thermal conductivity can be divided into the following three types: \x0d\ ① ReeferContainer, which mainly transports frozen food and can keep a certain temperature. It is specially designed for transporting food such as fish, meat, fresh fruits and vegetables. 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 kind of box has no refrigerator, but only heat insulation structure, that is, there are air inlets and air outlets on the end wall of the container, and the box is installed in the cabin, and cold air is provided by the refrigerator on board. This kind of box is called clutch refrigerated container (also called external or clamp refrigerated container). \x0d\ ② Heat insulation container It is a container with sufficient heat insulation structure, which is used to hold fruits, vegetables and other goods to prevent excessive temperature rise and maintain the freshness of the goods. \x0d\ is usually used for ice as refrigerant, and the heat preservation time is about 72 hours. \x0d\ ③ VentilatedContainer It is a container with air holes on the end wall and side wall, and is used to transport fruits, vegetables and other goods that do not need to be frozen. If the vent is closed, it can also be used as a grocery container. (3) TankContainer is a container specially used to transport liquor, oil (such as animal and vegetable oil), liquid food, chemicals and other liquid goods. It can also carry other liquid dangerous goods. There are several kinds of this kind of container: single tank and multi-tank. The four corners of the tank are composed of pillars and struts. Due to the high strength of the side wall, bulk goods with relatively high density, such as malt and chemicals, are generally loaded, while the latter is used to load grains with relatively low density. The loading port at the top of the bulk container should be provided with a waterproof cover to prevent rainwater from invading the container. \x0d\ (4) PlatformBasedContainer It is a container without top wall and side wall, even the end wall has been removed, and there is only one bottom plate and four corner columns. This container can be loaded and unloaded from front, back, left, right and above, and is suitable for loading long and heavy goods, such as heavy machinery, steel, steel pipes, wood and steel ingots. Gantry containers are not watertight, so damp goods cannot be shipped or covered with canvas. \x0d\ (5) PlatformContainer This container is a special structure container which is simplified on the platform container and only keeps the bottom plate. Length and width of the platform. The size of the container bottom is the same as that of the international standard container, 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. \x0d\ (6) OpenTopContainer This is a container without a rigid top, but it has a canopy made of canvas, plastic board or plastic-coated board, supported by a foldable or foldable top beam, and other components are similar to ordinary containers. This container is suitable for loading large goods and heavy goods, such as steel and wood, especially fragile heavy goods, such as glass plates. It is not easy to be damaged when hoisted into the box from the top by crane, and it is also convenient to be fixed in the box. \x0d\ (7) CarContainer It is a special container for transporting small cars, which is characterized by installing a steel frame at the bottom of a simple box, usually without box walls (including end walls and side walls). This kind of container is divided into single layer and double layer. Because the height of the car is 1.35 m- 1.45 m, if it is installed at 8 feet (2; 438 meters), its volume will waste more than 2/5. As a result, double-decker containers appeared. This double-deck container has two heights: one is 10.5 feet (3.2 meters), and the other is twice as high as 8.5 feet. Therefore, automobile containers are generally not international standard containers.
