Marina Maxi (8 STRAND)
Combination Dual Fiber (Polypropylene-Polysteel)

Product Description

Marina Maxi is far technologically superior, it surpasses the strength and other properties of normal polypropylene rope. With very high Strength/Weight ratio, it allows substantial size reduction, ease in handling and provides overall economy. Marina Maxi rope retains superior breaking Strength originated from technically reinforced composition of High Grade Synthetic Compound with Polyester and Polypropylene. In addition to the other superior properties, this ideal composition and construction creates extremely low elongation that offers stability during usage.

The Company
Axiom Impex International Limited is the Company in India that supply Ropes under OCIMF Guidelines.

Cyclical loading test
The test equipment is designed to be used for cyclic loading tests of ropes made of synthetic materials which will be used in applications exposed to cyclic loading in service. The procedure of prototype rope testing for determination of the TCLL value is specified in OCIMF (OIL COMPANIES INTERNATIONAL MARINE FORUM) guidelines.

Test Procedure
The cyclic loading test is performed at defined levels of loading in wet conditions. The rope sample is loaded with the prescribed number of cycles at individual levels of loading at a prescribed rate until the sample breaks or 2000 cycles at an 80% level of loading is achieved. The achieved number of cycles is used to calculate the TCLL level of loading at which the rope would break at 1000 cycles. The test course is continuously recorded by means of a computer and the final test report is based on this computerized record.

Elongation Test
Total stretch represents the entire length change in a new rope when placed under a given stress (load) and includes the non-recoverable, recoverable overtime and immediately recoverable portions of extension. One of the variables affecting percentages of elongation is intermittent loading vs. sustained loading; plotted graphically, the curves are somewhat different. Two marks are made on Marina Maxi Rope 30 inches apart, then tightly knot up a piece of string or twine made of same material through the strands at these marks. The string measure 34-1/2 inches between knots. When the rope is put under load of 20% of its breaking strength it is elongated less than 15% between the two knots 30" apart when relaxed will now be 34-1/2" apart (30"+0.15x30 = 34-1/2") and the string is taut.

Conclusion
If the string would have snapped out then it is to be believed that the rope has been loaded more than the breaking strength as well as if the distance have been more than 34-1/2" then the elongation is more than 15% which is not the case in our sample.
