WCB air applied and spring applied water cooled brakes are designed for applications requiring high horsepower absorption. Its design incorporates copper alloy wear plates which transfer heat rapidly to circulating water. They are used for heavy-duty braking and tensioning applications, such as those found in metal and paper processing, as well as for cable tension control on logging, marine mooring and winching equipment. The unit can also be used as an absorption.
