NR MAXIPACT® and NR MAXIPACT® PPI

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:

All cranes and performance lifting devices where non-rotating and high MBL ropes are required.

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