A helicopter pay-off block is a special piece of equipment used to install power transmission lines or other operations that require hanging cables. They are usually operated by both helicopter pilots and ground operators.
This device usually consists of one or more pulleys, which are fixed under the helicopter's lifting system. When the helicopter is suspended in the air, the ground personnel connect one end of the cable or transmission line to the pulley. The helicopter then hangs and flies slowly, carrying the cable or transmission line from the starting point to the destination. The pulley design of the helicopter pay-off block can effectively reduce the friction between the cable and the air obstacles, and ensure the smooth transmission of the cable to the destination.
Helicopter pay-off blocks are often used in areas that need to be crossed over difficult terrain or that cannot be reached by traditional methods. They are widely used in the power industry, construction and emergency rescue. The use of helicopter pay-off blocks can improve the efficiency of cable laying, shorten the engineering cycle, and can be quickly deployed to any location when needed.
