Weight restrictions for air cargo loading on airplanes

Due to the limitations of aircraft structure, aircraft manufacturers have set a weight limit for each cargo hold, and the weight of the cargo loaded cannot exceed this limit under any circumstances. Otherwise, the structure of the aircraft is likely to be damaged, posing a threat to its safety. Narrow body machines can only load loose cargo and cannot load containerized cargo. The weight of each piece of goods is generally less than 80 kilograms, and the volume is generally not more than 40cm X 60cm X 100cm; Wide body aircraft can load both bulk cargo and containerized cargo, with each cargo weighing generally no more than 250 kilograms and a volume generally not exceeding 100cm X 100cm X 140cm. For cargo exceeding the above weight and volume, it should be decided whether to ship it based on the route, aircraft type, loading and unloading equipment conditions at the departure, transit, and destination stations, and after obtaining the consent of relevant airlines. Specific weight restrictions for aircraft models: Taking the common carrier model B737 as an example, its payload capacity is 5-8T. The B737-200 and B737-300 models have a payload capacity of 5731kg (2269kg in the front cargo hold and 3462kg in the rear cargo hold), and the B737-800 model has a payload capacity of 8408kg (3558kg in the front cargo hold and 4850kg in the rear cargo hold).
