Synthetic Helicopter Longlines
Trusted and field-proven synthetic longlines. When quality, safety and durability are at the core of your operations; trust Ravenox. Made using the highest caliber materials and techniques, Ravenox Helicopter Longlines are a lightweight workhorse for light, medium and heavy-lift helicopter underslung and utility operations. Ravenox longlines are certified to meet manufactured specifications and each system includes a certificate of conformance and test in accordance with readings as specified by ASTM E-4 standard practices for force calibrations and verification.
Ravenox uses 12 strand HMPE fiber to create an ultra-high strength, lightweight helicopter underslung cargo long line. HMPE is widely used to replace wire-rope where extremely low-stretch and high strengths are required. Its resistance to abrasion and chemicals is unsurpassed by any other synthetic fiber.

BENEFITS AND FEATURES OF HMPE ROPE
- HMPE has the lowest stretch of any rope available
- Low creep
- Soft hand
- Torque free
- Easy splicing
- Neutrally buoyant in water

12 strand is the highest strength synthetic rope available. 12 strand is manufactured from High Modulus Polyethylene (HMPE) that has been enhanced by a recrystallization process.
12 strand is delivered standard with a polyurethane finish and is easily spliced using a simple lockstitch type splice, 4-3-2 or 5-4-3 tuck splice. It's soft, torque free braided construction provides easy handling.
