Python® Ultra
Super high strength for engineered applications (Force Pac® swage compacted)
- 10-strand fatigue resistant ULTRA high strength rope
- ForcePac® compacted design results is highest strength
- ForcePac® for lowest sheave contact pressure
- DoPar® Inner strands are laid parallel to the outer strands to avoid any strand cross-overs and premature wire nicking
Main Applications
Super high strength wire rope mainly used for engineered cable assemblies, counterweight ropes, winch lines, boom pendants, extension- and retraction cables, etc. Overhead crane applications for sizes above 3/4″
(19 mm) may require some restrictions as to fleet angle
(max. recommended 2˚) and lay direction.

Rope Characteristics
Python®-Ultra is our highest strength rope available. It is fully compacted resulting in an extreme smooth outer rope surface and the removal of nearly all of the constructional stretch. This is an important feature if you require a low stretch rope for cables assemblies. Ultra is an ‘all parallel’ construction type, meaning that there are no wire cross-overs within the rope body to ensure maximum fatigue life. Ultra provides a strength increase of up to 53% over regular 6-strand constructions. Refer to the conservatively calculated strength tables.
Python®-Ultra requires corresponding drum grooving directions; e.g. use a right hand lay rope if the drum is left hand grooved. 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.
