Low Torque Ropes

LT = Low Torque

Rotation resistant (but NOT non rotating)
Galvanized wires
Flexible - Lang's lay
High Breaking Load
For multilayer spooling
Resistant against drum crushing

Plastic Protected Impregnated (PPI) core

Leads every component of the rope to an homogeneous stress and behaviour in service
Improves the structural stability
Encapsulates the lubricant of the core
Protects the core from corrosion

PPI results in:

PPI core improves the basic properties of the LT 24 K and can allow working with higher fleet angle (1°30 < α < 4°30).

Protects the core to prevent from undetectable inner breaks
Structural stability
More homogeneous behaviour under extremely severe conditions

LT 24 K PPI

Rotation Resistant High Performance Steel Wire Rope

The LT 24 K PPI rope has 12 outer strands and can replace all the traditional 19x19 or 18x7 ropes, achieving a far better performance thanks to its Warrington core design. LT 24 K PPI is classified as Category 2 wire ropes.

Its properties lead the LT 24 K PPI to be used in other applications than tower cranes or mobile cranes, such as overhead cranes (when height can be critical) or luffing wire (when the distance between the sheaves is important).

It can prevent or eliminate the block twisting effect.

Main Properties

Rotation resistant (but NOT non rotating)
Galvanized wires
Flexible – Lang’s lay
High Breaking Load
For multilayer spooling
Resistant against drum crushing

Applications:

Tower cranes, all marine and offshore cranes when rotation resistance is required.
Recommended for intensive use and severe hoist applications where rotation resistance property is required.
