Python® Ultra when fabricated into a Uni-Loc® Cable Assembly
     
 
 
   
Do NOT use Python® Ultra wire rope attached to a swivel. The rope WILL unlay resulting in an unsafe condition.

Block Twisting (Cabling) will occur when used exceeding certain lifting heights. Call for advice
 
 

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 and lay direction. Call before you select this rope.

Rope Characteristic:
Python® Ultra is our highest strength rope available. It is fully swage 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.

Standard:
EN 10264, 12385 where applicable

Python® Ultra is NOT rotation resistant or non-rotating

Python® Ultra is available in right- and left hand lay. Ask for availability from stock.
     
     
Breaking Strengths
Note: The maximum CAPACITY, WORKING LOAD LIMIT (WLL), or LINE PULL of the rope usually is 1/5 of the below stated values. For specific information consult the standards applicable to your rope application.
     
10-Strand Ultra High Strength Wire Rope

Construction:
10 x 19 Seale (up to 3/4")
10 x 25 Filler (7/8" and up)

Ultra high strength type mainly used as high fatigue resistant rope for engineered cable assemblies. Up to 55% strength increase over standard 6-strand constructions. Sensitive to introduced rotation so call before you select this type of rope for overhead crane applications.

Rope Characteristic:
• Ultra High Strength
• All steel, parallel construction
• Flexible 10 outer strand type
• Fully compacted
• Smooth rope surface
• High fatigue resistant
