No Magnetic Wire Rope Lebus Grooved Winch Drum 30m Rope Welded
High Polymer No Magnetic Wire Rope Lebus Grooved Drum Sleeve
Advantages of LEBUS groove
LEBUS drum sleeves
My company developed the production of polymer drum leather, using the molecular weight of more than 1.5 million linear structure material (the molecular weight of ordinary materials only 20 ~ 300 thousand) processing LEBUS rope groove.
Due to the high molecular weight, with impact resistance, low temperature resistance, self-lubrication, absorption of impact energy and other comprehensive characteristics. Polymer drum skin, mainly supporting imported hoist and domestic large, super large hoist drum, prevent rope squeezing or biting rope damage to the wire rope between each layer can be smooth transition
LEBUS rope groove roller skin is suitable for single rope or multi-rope mine hoist, the use of wire rope winding more than one layer, in order to reduce the rope in the upper layer winding (over rope) bite rope, squeeze rope and other adverse situations of wire rope, in order to achieve a safe and stable over rope transition, prolong the service life of equipment and wire rope. It can be welded or drilled through holes and fixed with nuts.

Service conditions of Lebus groove
1. The flanges of drum shall be perpendicular to drum wall at any conditions,even under the load.
2. The rope must be kept under tension in the process of spooling so that the rope will be crushed against groove wall. When spooling can not meet this condition,a press roller shall be used.It is generally recommended that the tension of the rope should be at least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5 degrees and not less than 0.25 degrees.
4. When the wire rope released from the drum goes around the sheave,the center of sheave should be over the center of drum.
5. The rope must be kept round,not loose,even under the maximum load.
6. The rope must be anti-rotation structure.
Pls measure the change of rope diameter under different load
Product Structure
Groove Drum Composition: Drum core, Flanges, Shaft, Etc
Processing: Rope drums with grooves cut directly into them.Winch drum with flange, the LBS groove is cut directly into the body of the drum, according to customers’ requirements, the flanges are either welded or screw-bolted. groove geometry is determined by rope construction, diameter and length, and by application. the drum has the required mounting dimensions for the actual operating conditions.
