The Wrap on Wire Rope Spooling
As winching has evolved and improvements made, the industry gets stronger and is able to meet more challenges. However, something as simple as improper rope spooling can shut down a job. Here you will find the facts you need to keep your winch rolling.
The development of wire rope for winching was revolutionary, but it comes with some technical challenges that users must be aware of for safe and efficient winch use. One issue that can arise is a problem with the way the rope wraps around the drum. You can usually figure out pretty quickly what your problem is, based on the way the rope is spooling.
Rope Spooling in Center - a possible cause for this may be because the distance between the winch and the first sheave is too short. This may mean that the fleet angle needs to be adjusted.
Uneven Spooling - This could mean that the wire rope lay is not correct or the load on the winch is too light for the amount of pull. The first layer of wire rope installed on the winch drum may not be correct. Simply readjusting the first layer line would probably take care of the issue.
Rope Climbs Flange Side - If the hoist is not mounted perpendicular with the first sheave, or the center of the winch drum is not aligned with the first sheave, the wire rope may climb on side of the flange, and not wrap evenly. This can also occur if the drum flanges are not straight.
If the wire rope is climbing both flanges, the distance between the winch drum and the first sheave is too great.
Rope Knives Into Lower Layers - Possible causes could be the lower wire rope layers not installed properly due to a light load, a grooved winch drum, or the groove and wire rope sizes are mismatched.
