Some other types of mobile cranes do not require outriggers for stability. Aerial cranes are versatile and can perform various tasks ranging from aerial surveys to material transport. Roman engineers further developed Greek crane designs, using complex pulley systems and large treadwheels to lift over 60 tons. Thats because theyre able to maneuver in tighter spaces, access harder-to-reach locations, and perform in all types of weather and terrain. While helicopter suspension initially used a four-cable configuration system affixed with a manual attachment and detachment systemknown as a cargo slingthis basic suspension system was quickly improved by the addition of a cargo hook controlled by the pilot. These places include, but are not limited to: The most significant advantage of an aerial crane is its flexibility.
