Unreeling New Rope
- Remove rope properly from reels to prevent kinking. The rope should be removed by pulling it off the top while the reel is free to rotate. To proceed in any other manner may cause kinks or strand distortion. Never unreel rope from the side of the drum.
- Never stand in line with rope under tension. If a rope fails it can recoil with lethal force. Synthetic rope has higher recoil tendencies than natural fibre rope. Reverse rope ends regularly. This permits even wearing and assures a longer, useful life.
- Wherever possible abrasive conditions should be avoided. All rope will be severely damaged if subjected to rough surfaces or sharp edges. Chocks, bits, winches, drums and other surfaces must be kept in good condition and free of burrs and rust. Pulleys must be free to rotate and should be of proper size to avoid excessive wear. Clamps and similar devices will damage and weaken the rope and should be used with extreme caution. Do not drag rope over rough ground. Dirt and grit picked up by rope can work into the strands, cutting the inside fibres.
- Most synthetic fibres will withstand small doses of common chemicals. If you have any doubt please contact us for clarification. It is generally advisable to avoid exposure to chemicals where possible.
- Temperature has an effect on tensile strength. The tensile strength charts apply to ropes tested at normal room temperature. Ropes have lower tensile strengths at higher temperatures. Also continued exposure at elevated temperatures can melt and part synthetic ropes or cause permanent damage.
- Join rope by splicing. Knots can decrease rope strength by as much as 60%. Other terminations can be used but their strength loss with a particular type of rope and construction should be determined and not assumed.
Storage And Care
- All rope should be stored clean, dry, out of direct sunlight, and away from extreme heat. Some synthetic rope (particularly polypropylene, polyethylene, and aramid) may be severely weakened by prolonged exposure to ultraviolet (UV) rays unless specifically stabilized and/or pigmented to increase its UV resistance. UV degradation is indicated by discoloration and the presence of splinters and slivers on the surface of the rope.
- Avoid using rope that shows signs of aging and wear. If in doubt, destroy the used rope. No type of visual inspection can be guaranteed to accurately and precisely determine actual residual strength. When the fibres shows wear in any given area the rope should be re-spliced, eliminating the damaged area.
- Check the line regularly for frayed strands and broken yarns. Pulled strands should be rethreaded into the rope if possible. A pulled strand can snag during a rope operation.
- Both outer and inner rope fibres contribute the strength of the rope. When either is worn, the rope is compacted or hard which indicates reduced strength.
- Ropes can be damaged in many ways. The main causes are UV rays, chemicals, oil, sharp objects, and abuse.
- Don't store your rope in direct sunlight.
- Avoid excessive exposure to oil, chemicals, and chemical fumes.
- Using a rope bag will prolong the life of your rope.
- Never step on your rope. This grinds particles of dirt into the rope's core causing abrasion.
- Give your rope a bath on occasion.
- Retire your rope, when it shows signs of wear.
- Inspect each line before use. It is impossible to state when to replace a line, but if you have any doubts, about the integrity of the line, replace it.
