Cost saving special design not disorderly rope lebus grooved winch drums sleeves
Conditions of use of LEBUS rope trough
With the gradually widespread use of high lift winch, it is more and more common to use LEBUS rope groove drum to solve the multi-layer winding problem of wire rope. In order to better design LEBUS rope groove drum, play the advantages of the product itself, you must understand the specific applicable conditions of LEBUS rope groove drum.
1. The flange of the drum must remain perpendicular to the wall of the drum under all conditions, even under load.
2, in order to avoid the phenomenon of wire rope hopping or derailment, leBUS rope groove drum wire rope must maintain enough tension to make the wire rope can always be close to the surface of the rope groove, when this condition is not met, the wire rope press roller should be added.
3, the rope deflection Angle should be kept at about 1° and the maximum is not more than 1.5°. If this condition cannot be met, the rope deflection Angle compensator must be used to correct it.
When the wire rope released from the LEbus rope groove drum is wound around the fixed pulley, the center of the fixed pulley must be aligned with the width between the flange of the drum, and the LEbus rope groove drum must maintain its unlooseness and round shape even under the maximum load.
Lebus rope groove
Lebus rope groove is originated in the United States, invented by Frank.L. Lebus, the founder of LEBUS International Co., LTD. Abroad, this kind of rope groove is generally called LEbus Grooves, that is, for many rope grooves,
It is commonly known as the folding rope groove in China. Lebus claims that the diameter of the wire rope using the folding rope groove can be 100mm from 1mmDAO. The number of layers can reach 50 layers, the maximum diameter of the drum can reach 5m, the linear speed of the wire rope can be unlimited.
According to the existing data, the maximum diameter of the wire rope is 94RAM, used in Japan (sound Maru) ship's 500T crane, the nominal diameter of the drum is 2094mm, the drum flange spacing is 1953mm, a total of 7 layers of winding.
lebus groove sleeves
For efficiency and cost saving, the polymer drum leather developed and produced by our company adopts linear structural material with molecular weight of more than 1.5 million (the molecular weight of ordinary material is only 200,000 ~ 300,000) to process LEBUS rope groove, which is closely connected with the drum by spiral thread
High molecular weight, impact resistance, low temperature resistance, self-lubrication, absorption of impact energy and other comprehensive characteristics. Polymer drum skin, mainly supporting imported drum and domestic large, super large drum drum hoist, prevent wire rope extrusion or bite wire rope damage, so that the wire rope can smooth transition between the layers
