Python® Ultra
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
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
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.
