Carbon Steel Q335B Pair Of LEBUS Grooved Canble Drum Sleeves

This system is still the most effective and perfect method to prolong the life of wire rope. Tests have shown that the use with Wire rope specifications match the rope groove, Lebus drum can prolong the life of wire rope more than 500%.

LBS rope groove makes the load evenly distributed between layers, and the practice proves that it greatly prolongs the life of wire rope. In fact, the test surface can extend wire rope life by more than 500%. Reducing wire rope damage increases safety and reduces machine downtime.

The disadvantage of LBS rope groove drum is that it is more complex, so it is a little more expensive than the spiral rope groove drum. However, this additional cost is quickly compensated for by the savings in wire rope, which is expensive and takes up production time to replace.

LBS rope groove drum also requires certain operating conditions. The most important of these conditions is the deflection Angle of the wire rope, which is the Angle between the wire rope from the reel to the first fixed pulley. Generally speaking, this deflection Angle should not be greater than 1.5° and should not be less than 0.5°. There are some slight differences (about a 0.25° variation), but it is good to remember this general statistic. The optimal deflection Angle also depends on the load, cable structure and lifting speed. This deflection Angle indicates that for every 10m from the drum to the pulley, the distance between the wire rope and the midpoint of the drum should not be greater than 260mm (520mm between the two flanges). 9 Q2 ` 2 L! For LBS groove reels, if the deflection Angle exceeds the recommended range, a special rope called Angle compensator can be used to relax and be damaged by extruding or twisting of the outer wire rope onto the groove

LBS groove in each circle inside the drum are composed of straight line groove and diagonal rope groove, and each circle straight wire rope groove and diagonal rope groove position is exactly the same. when the wire rope for multi-layer winding, through the diagonal rope groove fixed upper wire rope and the lower rope crossover point position, the crossover of the upper steel wire rope in the oblique line. in the straight rope groove,the upper steel wire rope completely falls into the grooves formed by two lower steel wire ropes, form line contact between ropes, the contact between the upper and the lower rope is stable,when the return line, step retaining ring with return flange on both ends of the drum,guide wire rope to climb smoothly and return, avoid the rope disorder caused by mutual extrusion. so The wire rope is orderly and smoothly transferred to the upper layer ,Realize multi-layer winding.
 

LBS drum is a kind of groove for multi-layer winding of wire rope introduced from abroad. Because of this rope groove in the drum

Most of the circumferential section is kept parallel to the flange end face, only in a very small section and the flange end face intersection,

However, there is a phenomenon of turning, it is named "folding rope groove" too.

Years of practical use has proved that this kind of drum with special rope groove structure can well solve the difficulty of multi-layer winding rope

The double folding cable groove system ensures that the multi-layer winding wire rope on the drum is completely smoothly drawn into and rolled out of the drum.

This system is still the most effective and perfect method to prolong the life of wire rope. Tests have shown that the use with Wire rope specifications match the rope groove, Lebus drum can prolong the life of wire rope more than 500%.
