Helicopters with articulating rotors (usually designs with three or more main rotor blades) are subject to "ground resonance" and may, on rare occasions, suddenly lift off the ground to avoid severe damage or destruction. Sometimes, when its necessary to lift a load on a particularly long or short sling, single-point suspension systems affix the load to a swivel mechanism, which minimizes the risk of damage to the helicopter and suspension line. Aerial crane helicopters are most often used for transportation of hefty materials, rooftop unit installations, and utility construction projects, using rigging devices like cables and slings to lift heavy loads and transport cargo more efficiently. Plus, theres no potential for traffic delays or destruction of surrounding landscapesboth of which are a strong possibility with a standard ground crane. Using cables wound around a hydraulic drum, helicopters usually employ capstan winches to increase the structural stability, efficiency and durability of hoist systems.

Signal systems between aircrew and ground personnel shall be understood and checked in advance of hoisting the load. A construction helicopter, or aerial crane, is a helicopter used in construction projects to transport cargo and lift heavy loads more quickly and efficiently. Multi-point hoist systems are far less common, but are sometimes used to combine the load stability of multi-point suspension with the pickup and line positioning capabilities of hoisting. Missing a flight is something to avoid at all times. Generally, primary, or belly, cargo hooks are mounted directly underneath a helicopters frame, affixed to the fuselage of the aircraft. Helicopter cranes are typically equipped with a heavy-duty hook or cable that allows them to easily lift, move, and position a wide range of materials. While an aerial crane is not appropriate for all projects, it outshines traditional cranes where speed, maneuverability, and savings are essential. Most often, single-point suspension systems attach the cargo to a helicopters cargo hook through a long line and ring pendant, which helps to disperse any twisting or wrenching of the load. Another helicopter used for crane service is the Bell 204/205. Aerial cranes are often far more cost-effective than traditional ground cranes. A helicopter crane can reach great heights, remote areas, and environmentally sensitive areas. Home; Industry Insights.
