Mondel 300M Series Brakes, AIST mill duty rated, 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. 

The 300M range is very flexible and consists of a basic movement which can be fitted with a variety of DC, and AC. The many optional features make the basic brakes suitable for a large number of different applications.
