Spooling Wire Rope On Winch Drum

If you are winding wire to a bumper mounted winch pass the wire over the top of the winch spool toward the back of the truck.

Spooling wire rope on winch drum.

The full drum capacity is calculated below using the formula below. Start spooling the wire rope in the form of a right hand helix. You some drums are fitted with a trapezoidal guide attached to one. For a winch with lebus grooving experience has shown that the angle should be between 0 5 degrees.

Lebus system the lebus system is a method of controlling the spooling of wire rope on a winch drum so that there is no practical limit to the number of layers that can be spooled with safety irrespective of the severity of load and speed conditions or the sizes of rope and drum. Wire rope tends to spool toward the center of the winch drum. Of the flanges filling the space between the first wrap and the flange. When spooling wire rope onto a drum it is necessary for the rope to come onto the drum at a very slight angle just enough to encourage each wrap to sit tidily next to the previous wrap and for each layer to ride cleanly onto the layer beneath.

It is measured between the first fixed sheave and the flange of the winch. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. Winch drums for multilayer wire rope spooling when the first layer has filled the drum the second layer then travels back across the drum with each wrap of rope sitting precisely along the groove of two wraps of the first layer. Pass the end of your wire rope over the top of the drum toward the rear of the winch.

Wire rope should be attached at the correct location on a flat or smooth faced drum so that the rope will spool evenly with the turns lying snugly against each other in even layers. The load on the winch is to light. Rope comes off the sheave onto the winch. First layer of wire rope installed on winch drum is not correct.

The wire rope lay is not correct. The distance between the winch and the first sheave is too short. Press the end of the wire rope into the side insert slot and between the clamp jaws. Correct fleet angle is crucial to smooth spooling.

Spooling a wire rope onto a drum. This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope. In actual practice drum capacities may be 25 30 less than the values given by this formula due to uneven spacing loose winding and overlapping. If the rope comes onto the drum at the wrong angle the rope is likely to experience spooling problems and rope life will be affected.
