Which type of rope suits you best?
​
When choosing the optimal rope for your needs, understanding the array of options available for varying conditions is crucial. To determine the most suitable rope for your requirements, consider the following factors:
​
Strength: Essential for lifting loads and performing tasks effectively, requiring quality fibers or filaments to achieve full strength.
Abrasion Resistance: Ensures extended durability when subjected to pulleys, winches, or other wearing or torsion conditions.
Water Repellency: Prevents swelling when wet, maintaining flexibility and manageability even in damp conditions.
Flexibility: Enables agility and easy handling in diverse working conditions, particularly crucial for safety in falls, slings, hoisting, mooring, and towing lines.
Know your rope needs.
Correct sizing is paramount, as undersized rope can endure undue strain. Selecting the appropriate rope size is key to maximizing its utility and lifespan. Alongside size, considerations such as type of lay and specialized fiber treatment (for Manila ropes) influence rope selection. Many industries have identified specific rope types best suited for particular tasks, with some even developing special-purpose ropes to address unique needs. Typically, past experience and recommendations from your supplier can guide the specification of the proper size and type of rope for your application.
Caring for Your Rope - Ensuring Optimal Service
​
To maintain the expected level of service from good rope and ensure the safety of both personnel and materials, it's essential to handle and utilize rope with care. By adhering to the following guidelines for rope selection, handling, and storage, you can ensure its reliability and safety over prolonged periods.
​
Cleaning Guidelines:
​
-
If rope becomes muddy or dirty, it can be washed with cold water and moderate hose pressure, but avoid using steam.
-
After drying, any remaining grit or dirt should be shaken out.
-
Wet rope or rope containing metallic strands should not be used near power lines or other electrical equipment, and it should never be left in a position where it may freeze.
-
With proper care, additional lubrication beyond what's inherent in new rope is unnecessary.
-
Avoid sharp bending of the rope around objects too small for its size or over sharp corners, as this can cause extreme tension or abrasion on the fibers/filaments. Ensure bends are appropriate for the rope size, and pad sharp corners or rough surfaces.
​
Coil Removal Technique:
-
To prevent distortion of the rope's lay, always remove rope from the coil in the following manner:
-
Lay the coil flat with the inside end of the rope closest to the floor or deck.
-
Loosen lashings and coverings.
-
Reach down through the center of the coil and pull the rope up from the inside.
-
End Reversal:
-
Regularly changing ends of the rope when used in tackle promotes even wearing and extends its useful life. If a short section exhibits undue wear or damage, cut out the worn section and splice the rope for optimal service, ensuring that the cause of excess wear is addressed.
Maintenance Tips:
-
Avoid dragging rope on the ground or over rough, gritty surfaces, as abrasive particles can weaken the fibers.
-
Store rope away from chemicals such as acids, alkalis, oils, paints, and barnyard mud, as these can quickly damage vegetable fibers.
-
Always ensure that the rope is clean and dry before storing, as storing wet rope can lead to mildew and rot.
-
Ideal storage conditions involve a cool, dry room with adequate air circulation. If storing on metal or concrete floors is necessary, protect the rope with planking to prevent contact with the floor.
Choosing the Right Rope for the Job:
The economy and efficiency of your project rely on selecting the correct size and quality of rope. Ensure a safety factor of at least five when determining the safe working load for new rope, and adjust this factor as the rope ages.
Inspection: Before placing new rope in service, conduct a thorough inspection along its entire length to ensure there are no signs of damage or defects. Afterward, inspect the rope at least every thirty days under normal conditions, or more frequently if it supports scaffolding or is exposed to acids or caustics. Look for wear, abrasion, broken or cut fibers, displaced yarns or strands, discoloration, or rot. Untwist the rope in several places to inspect the inner fibers, ensuring they are bright, clear, and unspotted. Remember that loading rope to over 75% of its breaking strength can cause permanent damage, detectable by examining the inside threads or noting a reduced diameter in the weakened section.
Preventing Kinks: Kinks can cause permanent damage and weaken the rope. Remove kinks promptly, and if the rope is continually twisted in one direction, restore balance by twisting it in the opposite direction.
Splicing for Durability: A splice is stronger than a knot, making it the preferred method for joining ropes or creating slings or endless ropes. While knots can reduce rope strength by up to 50%, a properly made splice may retain up to 95% of the rope's strength. Short splices provide the strongest coupling but double the rope size, while long splices, with up to 90% strength efficiency, are suitable for running through pulleys or sheaves on a block.
Consider Sling Angles: Small angles increase rope stress, so allow for sling angles when using rope slings. While employing slings properly can substantially increase the safe working load of the rope, smaller sling angles significantly increase the load factor on each leg of the sling. Aim to keep sling angles between 45 and 90 degrees for best results.
Avoid Sudden Strains: Jerking or sudden strain can cause failure, even in a rope that is normally strong enough to handle the load safely. Always apply a steady, even pull to ensure full strength from the rope, especially when using slings or tackle that may multiply strain and power.
