Hot Dip Galvanized Alloy Steel Tower Crane Electric Winch LBS Grooved Winch Drum
Tower crane winch:
Tower crane is referred to as tower crane, also known as tower crane, originated in Western Europe. A rotating crane with arms mounted on top of a towering tower. Large working space is mainly used for vertical and horizontal conveying of materials and installation of building components in building construction. It is composed of metal structure, working mechanism and electrical system. The metal structure includes tower body, boom and base. The working mechanism has four parts: lifting, luffing, turning and walking. Electrical system includes motor, controller, power distribution cabinet, connecting circuit, signal and lighting device, etc

Advantages :
LEBUS drum has a special key, is designed at the bottom of the reel end flange (end insert) and extension pieces, they guide the wire rope from the first layer to the second layer smoothly.
The lebus groove makes the load evenly distributed between layers, and the practice proves that the service life of the wire rope is greatly prolonged. In fact, the test surface can extend wire rope life by more than 500%. Reducing wire rope damage increases safety and reduces machine downtime.
Processing type :
Lebus grooved drum
The groove is cut directly into the body of the drum.(according to customer‘s requirements.
The flanges are either welded or screw-bolted.)
Split-lebus grooved sleeves (shell )
The whole lebus grooved drum is divided into the upper and lower parts,which we call them lebus split-sleeves. The sleeves are available a smooth drum or helical drums.
LBSD Series Grooved drum :

Overview:
Lebus drum is a kind of groove form suitable for multi-layer winding of wire rope introduced from abroad. Because this kind of rope groove is kept parallel with the flange end face in most sections of the drum circumferential direction, and only intersects with the flange end face in a very small section, the rope groove must be turned, hence the name "folding rope groove".
Years of practical use show that this kind of special rope groove structure of the drum, can well solve the problem of wire rope multi-layer winding rope about double folded cord slot system, to ensure that the multilayer on the drum winding rope fully involved in and roll out the reel smoothly, and can greatly prolong the service life of wire rope, the system is still the most effective method and the most perfect. Tests have shown that the Lebus drum can prolong the life of the wire rope by more than 500% with the rope groove matching the specifications of the wire rope.
