The AIST-NEMA rated mill duty brakes are designed for heavy-duty steel mill and other harsh environments and applications which require high integrity products.
The advanced design features, combined with fabricated steel construction, makes this range of brakes suitable for applications requiring reliable braking with the minimum of maintenance and downtime. Applications include steel mills, stacker reclaimers, shiploaders, port cranes, shipyard cranes, offshore drilling rigs, missile assembly cranes, incinerator cranes and large gantry cranes.
