A cargo hold is a designated space within a ship, aircraft, or other transport vehicles where goods and materials are stored during transit. It is designed to securely hold various types of cargo, including containers, pallets, and bulk items, ensuring they are protected from the elements and safely transported to their destination. In maritime shipping, the cargo hold is typically located below deck in a ship, while in airplanes, it is found in the belly of the aircraft. Proper management of the cargo hold is essential for maintaining balance and stability during travel, making it a critical component of logistics and transportation.
