They can lift anything within their lifting capacity, (cars, boats, swimming pools, etc.). Helicopters carry these tricky loads connected to cables or slings and place bulky machinery or freight in places that ground cranes or traditional cranes cannot reach. 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. And did you know that utility and construction helicopters can lift an average of 2,000 to 10,000 pounds? The aircraft does require a pilot and copilot for flights. A crane company played a part in helping construct the Chesapeake Bay Bridge that connects Maryland, Delaware and Washington D.C.; helicopters helped transport supplies and this bridge is considered one of the longest over-water bridges in the entire world. There is no better way to amass and aggregate all of the aerial shots you need than with a drone. Helicopter Express is here for you when you're ready to save time and money.
