Product structure:
Split wire rope groove sleeve: grooved split sleeves can be placed over smooth and ungrooved drums – suitable for modification or replacement of drum. Split-sleeve system consists of a pair of outer shells that are bolted or welded onto a smooth drum to provide a grooving pattern,The split sleeve is composed of spiral groove and parallel groove,the groove design conforms to the specified wire rope structure, diameter and length.
Product installation and Application:
1) the LBS rope groove sleeve is divided into two parts, which are made up of integral rope grooved drum. It needs to be used in pairs;
2) the LBS grooves can be mounted on smooth, grooveless drums or on winch drums with spiral grooves, It is suitable for the application of refitting or changing the drum.
3) The LBS rope grooved sleeves is installed on the winch barrel through bolt connection or group welding connection.
