Wire Rope Python ® Construct-6 Boom Hoist- and Overhead Crane Rope 6-strand crush resistant high strength rope compacted design to increase strength MaxFlat compression for optimum sheave contact Up to 7/8 - 24 mm 6 F-V 1” - 26 mm and up 6 WS-V Python® Construct-6 types are available in right- and left hand lay. Ask for availability from stock. Boom Hoist 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 Characteristic: 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 purpose intend to be compacted (or swaged) 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. Choose 6 F-V as Boom Hoist rope, 6 WS-V for single layer drum hoisting. Because of the compacting process most of the rope’s initial stretch (constructional stretch) has already been removed. Python® Construct-6 is NOT rotation resistant or nonrotating Standard: DIN 2078/3051 where applicable. Do NOT use Python® Construct-6 wire rope attached to a swivel. The rope WILL unlay resulting in an unsafe condition. -22- Block Twisting (Cabling) will occur when used exceeding certain lifting heights. Call for advice
Wire Rope 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.
