Electric Long Line

The electric long line consists of a heavy-duty rope and an attached electric cable. (The heavy-duty rope carries the external load under a helicopter. The electric cable provides electric power to a remotely-controlled hook which can be attached to the lower end of the long line.) The heavy-duty rope is made from high-strength, synthetic fiber and is rated to carry a 10,000 pound load with a 6.7-fold safety factor. In standard tensile tests the minimum strength of the cable 68,500 lbs. and the maximum strength measured was 81,600 lbs. The stretch when lifting a fully-loaded Heli-Basket is less than 0.5%, making this a light-weight, high-strength, low-stretch rope. Stretching the rope when lifting the load does not break the electric cable.

The core of the long line is Plasma^® rope. Plasma^® 12-strand rope is the highest-strength synthetic rope available. The 12-strand braided rope core is covered with a heavy-duty polyester braided jacket, which protects the core from abrasion. The polyester jacket is coated with bright orange urethane, which seals the jacket and protects the core from grit, oils, solvents, and ultraviolet radiation. The primary strands are torque-balanced so that the final rope is "torque-free." The long line has both excellent flexibility and strength retention under cyclic loading. It has very high resistance to electrical current.

The long line has an externally-mounted electric cable containing highly flexible, multi-strand 12-gauge (AWG) conductors--two current-carrying conductors and a ground wire. The connector plugs are strain-relieved and have reinforced connector blades. Standard connector plugs are used, allowing the cable to be quickly plugged into the helicopter above and the solenoid-operated remote hook below. The mandatory visual inspection before each flight is a "snap" with this externally mounted cable.
