Some loads might only need one cable to lift an object while others might require a dozen. Using cables wound around a hydraulic drum, helicopters usually employ capstan winches to increase the structural stability, efficiency and durability of hoist systems. While some two-point hoisting systems are used by aerial crane helicopters to lift complicated loads, most multi-point hoist systems couple multi-point suspensionusing various points of suspension on a cargo hookwith a single cable hoisting system. Because single-point suspension offers only limited movement restraint, multi-point suspension allows greater control and stabilization during long or sensitive cargo trips. A crane service is capable of lifting various objects, including whole antenna towers. Because helicopters are able to spin 360 degrees, hover over buildings and other structures, and maneuver in tighter spaces, theyre much more efficient for projects in big cities or mountainous terrain (and theres no need for approach roads!). Using rope or steel cable to secure an external load to a suspension system is potentially hazardous, often leading to problems with material strength, reliability and adaptability.
