Split Type Lebus Sleeve With Roll Plug Welded / Bolted Connection

Compared with the general non grooved (smooth) drum and spiral grooved drum, the Grooved Steel Drum has obvious advantages in the neat winding of multi-layer steel wire rope. lebus groove makes the winding of steel wire rope more smooth and the load between layers is evenly distributed, reduces the irregular, disorderly winding and rope biting in the process of steel wire rope arrangement, reduces the damage of steel wire rope, prolongs the service life of steel wire rope, improves the safety of equipment operation, and avoids the shutdown time of mechanical equipment due to disorderly rope replacement.
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.
In order to reduce costs, we produce LEBUS SLEEVES, which are also manufactured to the required size of the wire rope. The material can be either steel or nylon, butt-welded or bolted onto the reel. This ensures that the wire rope is wrapped in orderly layers on the reel. When the wire rope can also be replaced, only SLEEVE can be replaced instead of the reel, greatly saving the cost and time
 

Adopt plate blanking →→ roll cylinder and weld longitudinal welds →→ check longitudinal welds and geometric dimensions of cylinder (diameter, length, inner diameter ellipticity tolerance, etc.). For large diameter cylinder, add welding process reinforcement → machined annular groove of cylinder, There are requirements for the process of roughing the cylinder outside the circle to process the outer circle → cylinder length welding (namely ring seam welding). For the two ends of the cylinder need to add welding process reinforcement according to the process regulations, and check the quality of ring welding and machining allowance → cylinder length processing and both ends of the stop or groove processing → welding cylinder end flange plate, shaft, inner support ring, etc.

As LBSS series winch grooved sleeves have the above characteristics, it has wide application range.It can be applied in the aviation, shipbuilding,offshore crane industry, oil field, coal,port marine platform,construction,railway and other heavy machinery field.

Early introduction the advanced technics form domestic and foreign,after years R&D,our company had a major breakthrough in lifting machinery's multilayers spooling field and obtaied the production patent of LBS groove in 2010.Meanwhile we created our brand -LBS. At the prosent, the company have formed a stable and serialized production mode.
