Main Applications

High strength standard 6-strand rope for applications which require a crush resistant rope to be used on multiple layer winding systems; e.g. boom hoist on lattice boom mobile- and tower cranes. This rope has also shown remarkable performance gains as main hoist rope on port container cranes and on some overhead crane applications.

Rope Characteristics

Python® Construct-6 is a swaged rope which is constructed from specialty made engineered and sized 6-strand wire rope. The basic wire rope is already manufactured with the intention of being compacted (ForcePac™) into the finished product. The degree of compacting is carefully selected to ensure the best compromise between crush- and fatigue resistance. The strength increase compared to standard 6-strand ropes varies between about plus 10% to 35% depending on rope diameter.

Python® Construct-6 is available as a 25-wire (6 F-V) or 36-wire (6WS-V) construction, in left- and right lay, bright or galvanized.

Because of the swage compacting process, most of the rope's initial stretch (constructional stretch) has already been removed.

Standard

ASTM 1023/A 1023M Table 31
EN 12385-1 where applicable.

Python® Construct-6 is NOT rotation resistant or non-rotating.

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.

Python® Construct-6 ForcePac™ Swage Compacted

Construction:
6 WS-V (6 x 36 Warrington-Seale)

6-strand rope with flat outer wire surface resisting drum crushing and aiding in better multiple layer spooling. The ForcePac™ compacting process removes most of constructional stretch.
