Product Specification

Customized Steel Q355B Single Lebus Grooved Drum Hydraulic Pulling Winch 

Product Structure:

LBSW Hydraulic winch primarily consists of four parts, including oil distributor, hydraulic motor,brake,drum and stand. The oil distributor inciuled one-way balance valve, brake and high pressure shuttle valve.

Advantage Of The LBS Grroved

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.

Disadvantage Of The LBS Grroved

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.

Conditions of LBS grroved

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

Our company early introduction of advanced technology at home and abroad, after years of research and development and improvement, in the hoisting machinery multi-layer wire rope row rope field has made a major breakthrough,

In 2010, the company obtained the production patent of double folding rope groove drum, and founded its own brand - LBS. At present, the company has formed a mature and stable, serializedproduct production mode.

When the split type drum fence skin is installed, the split fence skin sleeve is wrapped on the smooth slotless drum, and is closely connected with the drum through bolts or welding, so that the original smooth surface of the drum outside the surface becomes the form of lebus double folding rope groove, which is convenient for the application of winch modification or replacement of the drum.

Our factory has more than 2000 sets of advanced equipment such as casting, forging, gear processing, sheet metal stamping, riveting, heat treatment and mechanical processing. In recent years, the

Germany CW1000 machining center, CNC four axis, five axis linkage machining center, CNC punch, large CNC hobbing gear grinding machine, large CNC floor boring and milling machine,

Vacuum electron beam welding, CNC welding robot and 80 roll machine and other advanced processing equipment.
