A cargo helicopter is a type of aircraft specifically designed to transport heavy loads and supplies. Unlike traditional helicopters, cargo helicopters often have larger cabins and stronger lifting capabilities, allowing them to carry equipment, materials, and even personnel to remote locations. They are commonly used in industries such as construction, logging, and emergency services. These helicopters can operate in various environments, including rugged terrains and disaster-stricken areas, making them essential for humanitarian missions. Notable models include the Sikorsky CH-53 and Boeing CH-47 Chinook, both known for their impressive payload capacities and versatility in cargo transport.
