Large Crane Winch Drum With Lebus Grooves Winding Cable Rope Automatic Row

Large Crane Winch Drum With Lebus Grooves Winding Cable Rope Automatic Row

Winch drum is an important part of crane. One end of the wound wire rope is fixed at the drum rope socket through a rope clip, and the other end. The guide wheel of the sky car is introduced into the trolley pulley group, and the trolley pulley group is installed. Equipped with hooks, faucets and drill pipe strings. When the winch works, it is wound. The steel wire rope on the drum realizes the action of winding and releasing the rope through positive and negative rotation of the drum. The drum bears the fast rope tension of the wire rope, and the drum structure must meet the strength. Outside, but also to ensure that the wire rope winding neatly.

The drum rope groove of drill winch adopts the form of double broken line structure, and its characteristics are diagonal rope groove and straight rope groove appear alternately, thus forming two diagonal rope groove area and two straight rope groove area on the surface of the drum. The so-called inclined rope groove refers to the rope groove that intersects diagonally with the drum bus, and the straight rope groove refers to the rope groove that intersects directly with the drum bus or is parallel to the flange. Diagonal strong groove controls the pitch of rope groove, which accounts for a small proportion in a circle of rope groove. Its structure point can effectively alleviate the problems of extrusion deformation, mutual friction and early wear of wire rope during loading.

The processing and production of the lebus groove can be directly processed on the drum as a whole, and can also be made into a set with the rope groove, and made into a split type, wrapped in the smooth drum when installed, connected with the drum through bolts or welding. The material of folding rope groove barrel can be divided into carbon steel, stainless steel, alloy steel, aluminum or glass fiber, etc. The barrel can be made by sheet rolling or casting.
