 RHEYFLEX®-PN
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.
