Heavy lift helicopters are specialized aircraft designed to transport large and heavy loads that are beyond the capacity of standard helicopters. These helicopters feature powerful engines, a robust structure, and advanced rotor systems, allowing them to carry significant weights efficiently. They are commonly used in various applications including construction, logging, disaster relief, offshore oil and gas operations, and military operations. Heavy lift helicopters are equipped with features such as external sling attachments for unpalletized cargo, and some models may also include large cargo baskets or removable cabins for versatile loading options. Their ability to operate in challenging conditions and access remote locations makes them crucial in tasks that require rapid transportation of heavy goods.
