Non-Rotating Ropes

NR = Non-Rotating

Non-rotating construction
Compacted strands
Lang’s lay flexible hoist rope
Galvanized wires
Fully lubricated (internal and external)
Extremely high Breaking Load

NR Maxipact 40(W)xK7

OPTION: 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

NR Maxipact 40(W)xK7 PPI
NR Maxipact PPI

PPI results in:

A longer service life
Keeping its non rotational properties in the most severe conditions
Internal rope protection against corrosive environment
Favoring outer maintenance
Recommended for all marine and submarine applications
and all environmental severe conditions.

NR MAXIPACT®40(W)xK7
Special design for a maximum unit length

Non-Rotating High Performance Steel Wire Rope

Non-rotating rope for tower cranes, mobile cranes and all the applications in which non rotational property is required. Optional Plastic Protected Impregnated (PPI) core recommended for offshore, deck cranes and marine environment.

Main Properties

Non-rotational: The design of the NR Maxipact generates its special geometrical assembly resulting in an optimal non-rotating property.

Safety: The construction of the NR Maxipact is designed to avoid cross nickings between the inner strands (core: Warrington construction). This protects the rope of internal deterioration. Outer broken wires will become first evident. (Visual inspection).

Applications:

Same technology and applications than the NR Maxipact in 34(W)K7 and 37(W)xK7

Optional Plastic Protected Impregnated (PPI) core recommended for offshore, deck cranes and marine environment.
