SYNTHETIC VS WIRE WINCHLINE ROPE
SYNTHETIC VS WIRE WINCHLINE ROPE can be a significant decision when selecting the right rope for your winch. Understanding the differences between synthetic and wire rope can help you choose the best option for your needs.
Abrasion/cut resistance
Synthetic rope is more prone to damage on sharp edges and rough surfaces than wire rope. Wire rope is more resistant but will also get damaged over time. Utilizing protective sleeves on synthetic rope can help reduce wear and tear; however, avoid winding the protective cover back inside the winch. It's important to note that synthetic rope can also collect debris and dirt, which may damage the rope from inside the strands.
Water
Synthetic rope is much lighter than wire and some types will float on water. Quality synthetic rope doesn’t absorb water and won’t rust but can freeze in cold conditions. In contrast, wire rope is heavier, sinks in water, and will rust over time.
Weight
Synthetic rope is 8 times lighter than wire rope, which can reduce manual handling issues. Wire rope is heavier and more cumbersome than synthetic options. For instance, a 12 strand 12mm synthetic rope at 100 meters weighs about 7.8 kg, while a 12mm wire rope (6x36) at the same length weighs approximately 60.2 kg.
Longevity
The lifespan of your rope largely depends on the application, handling, and care. Various factors, including frequency of use and environmental conditions, will affect durability.
Field repairs
A common misconception is that broken wire rope cannot be repaired in the field. With some basic skills, it’s possible to perform repairs on both types of rope. A variation of the flemish splice can be used for temporary field repairs of wire rope, while synthetic rope can be repaired using a hand splice. Though both methods are possible, they require the right tools and knowledge to execute correctly.
Equipment used with the rope
Ensure that pulleys and other equipment match the specific diameter and type of rope being used, as those designed for wire rope differ from those made for synthetic and fiber ropes.
Maintenance
Always refer to the manufacturer’s guidelines for proper maintenance of your rope. As a general rule, store rope in a well-ventilated and dry area when not in use. Minimize exposure to UV light, dust, moisture, chemicals, and extreme weather conditions. For wire rope maintenance, an occasional application of a lubricant such as heavy duty liquid lanolin can be beneficial. Careful handling is also essential to prevent kinks and crushed sections of rope.
Heat and UV
Wire rope is notably resistant to heat compared to synthetic rope, which can start softening at around 140°C and melts at approximately 152°C. A high-quality synthetic winchline will exhibit some UV resistance, but prolonged exposure to harsh sunlight can lead to deterioration over time.
Sizes
Your winch drum's design specifies the diameter and length of rope it can accommodate, so always consult the manufacturer before making any changes. Both synthetic and wire ropes are available in various sizes and working loads, with synthetic options often coming in different colors.
Price
A notable price gap exists between wire ropes and synthetic winchlines, with synthetic options typically costing about double that of wire rope.
Breaking force
Synthetic rope is 70% stronger than equivalent wire rope. There's a common myth that if synthetic winch line breaks, it will simply fall to the ground. However, if a winch line breaks while loaded, it can still whip back, albeit with significantly less force than wire rope.
So, what’s the verdict?
Ultimately, the choice between SYNTHETIC VS WIRE WINCHLINE ROPE depends on your specific use case. Both types come with their advantages and disadvantages, and selecting the right rope will hinge on your needs and applications.
