The cargo hook can be used to transport material to locations untouched by humans. It can also be used to position pylons, poles, antennas, etc. with a high degree of precision. Helicopters can reach unloading points extremely rapidly, saving customers time and money. When using helicopters to transport material, there is also no need to change the surrounding environment, as is so often necessary when positioning bulky and heavy cranes, erecting temporary scaffolding or providing access for land vehicles.
