Python® Power-9

• 9-strand fatigue resistant high strength construction
• Force Pac® design to increase strength
• Flat outer wires for optimum sheave contact
• Inner strands are laid parallel to the outer strands to avoid any strand cross-overs and premature wire nicking

Main Applications

Super high strength yet super flexible overhead crane wire rope. Used as original equipment rope and for crane capacity upgrades. Also used as high strength engineered assembly cable for tension applications. Power9 has little to no initial constructional stretch.

Sizes 11mm and 14 mm in left lay are original equipment ropes for some DEMAG crane types.

Rope Characteristics

Power9 is compacted to enhance the abrasion characteristic and to reduce sheave- and drum wear. Type Power-9V in combination with EEIPS (2160 N/mm2) wire tensile grades increases rope strength of up to about 50% over regular strength 6-strand types.

Power-9 is constructed from a total of up to 358 single wires compared to 265 single wires in traditional 6×36 wire rope. This results in a super strong yet super flexible rope.

Although Power-9 is our most successful high strength rope construction there are precautions we must address before you select this rope. One is that the direction of lay which must correspond to drum grooving, the other is that large fleet angles may cause high strands or core protrusion because the rope will ‘roll’ rather than ‘glide’ into the sheave groove. Any introduction of torque into (any) wire rope will cause structural damages.

6-strand		9-strand

The Python® Power-9 construction provides an increase in contact points between rope and sheave. Less wear on the rope and of your equipment.
