Cargo carrying helicopters

摘要

One of the advantages of helicopters is their ability to lift significant loads to extraordinary heights. They do so with the use of various hoisting means that can initially raise the load from the ground, before the helicopter undertakes some movement to the desired location for reimplacement of its carried load. Since cargo retrieving, including carrying, lines cannot dangle dangerously when not attached to a load winch-type hoists are generally employed. There are however certain disadvantages in the conventional mechanisms that render the usage of such hoists somewhat deficient, and even hazardous in certain applications. In addition, some operations require rapid pick-up of cargo or personnel within time constraints impossible for winch mechanisms. The helicopter herein carries cargo retrieving lines by means attached to the underside thereof, adapted to be rapidly lowered therefrom to retrieve cargo and capable of deployment.
