The Jac Wire drum coupling is designed for installation in drum driveof crane and conveying system.The Wire drum coupling can be used in the very difficult and roughoperating conditions of iron and steel works and continuos heavyload operation in shore cranes.
With compact design and capable of transmitting large radial load,enjoy longer life and minimum loss of power angular misalignmentcan be allowed up to 1.5 degree.
With design of decreasing slip movement of rollers by constructionof minimum backlash between crowned rollers and cylindrical bores,the relative movement between rollers and bores, which is cause ofwear, is considerably reduced due to the natural movement of drum
In the transmission of power, a stamping hardness of the rollersprofile is produced, with which higher wear resistence is achieved
