DP 8 K PPI High Performance Steel Wire Rope
Main Properties
Similar to the DP 8 K with an internal Plastic Protection Impregnation (same steel contruction).
The internal Plastic Impregnation offers an homogeneous behaviour to all the components.
The DP 8 K PPI gathers all the properties of the DP 8 K, and sharply eliminates its weaknesses, so it is less sensible to the fleet angle effect.
The Plastic Impregnation of the core encapsulates the grease for life, and, the DP 8 K PPI performs particularly in long periods of service for the hoist devices: Boom and pendant ropes, multifall hoist systems,…
- 8 outer strands closed in a parallel lay together with the inner core strands
- Regular lay
- Galvanized wires
- All compacted strands
- Extremely high breaking load
- Fitted for multilayer spooling and multipart reeving thanks
to its very high grade of flexibility
- Cannot be used when a fleet angle is >2°30
- High modulus of elasticity, low stretch
Applications:
When an extremely high MBL is required for a multipart reeving hoist system: electric hoists, twin hoist systems (right and left ropes), boom hoist and pendant rope for mobile cranes, tower cranes and all marine equipment.

ATTENTION:
Due to its particular full unilay parallel closing (outer/inner strands), this rope is very sensible to the rotation and fleet angle.
Cannot be used for big lifting heights, unguided loads, short number of falls, etc.
DP 8 K must never be used with a swivel.
