Aerial Crane
Helicopters used to lift heavy loads are called aerial cranes or skycranes. As aerial cranes, helicopters carry loads connected to long cables or slings in order to place heavy equipment when other methods are not available or economically feasible, or when the job must be accomplished in remote or inaccessible areas, such as the tops of tall buildings or the top of a hill or mountain, far from the nearest road. Helicopters were first used as aerial cranes in the 1950s, but it was not until the 1960s that the popularity of the use of skycranes in the construction and other industries began to catch on. The most consistent use of helicopters as aerial cranes is in the logging industry to lift large trees out of rugged terrain where vehicles aren't able to reach, or where environmental concerns prohibit the buildings of roads. These operations are referred to as longline because of the long, single sling line used to carry the load.

Famous quotes containing the words aerial and/or crane:
“A sociosphere of contact, control, persuasion and dissuasion, of exhibitions of inhibitions in massive or homeopathic doses...: this is obscenity. All structures turned inside out and exhibited, all operations rendered visible. In America this goes all the way from the bewildering network of aerial telephone and electric wires ... to the concrete multiplication of all the bodily functions in the home, the litany of ingredients on the tiniest can of food, the exhibition of income or IQ.”
—Jean Baudrillard (b. 1929)
“Yet, to the empty trapeze of your flesh,
O Magdalene, each comes back to die alone.
Then you, the burlesque of our lust—and faith,
Lug us back lifeward—bone by infant bone.”
—Hart Crane (1899–1932)
