Rubber Pendant Overhead Crane Cables
Applications
Rubber cable with a central strength member used for control, measurement and signalling in the steel, mining and chemical industries.
In addition as cantilevered control cable for cranes (e.g. to remote control on overhead cranes with pushbutton boxes), wind turbines, conveyor and storage systems.
