Due to their heavy load lifting capacity these Ropes are well suited for hauling and cargo lifting operations. Ports And Shipping Manila Ropes of various diameters are widely used for towing, mooring and dry docking by Port Trusts and Shipping Industries. Manila Ropes offer excellent resistance to action of water and marine organisms, and are therefore ideally, suited in the Marine Industry. Transport Sisal Ropes find wide applications in the domestic transport industrY for safe handling of cargo. Due to their excelient shock absorbing capability Ropes are acknowledged to be the most reliable for this end use. Weights are subject to +- 5% maximum variation. Tensile strengths are approximately average and the minimum shall be within minus 1O% of the listed value. The values shown above are for regular aly ropes
