UPGRADING LIFTING MACHINES MADE BY NOVOKRAMATORSK MACHINE-BUILDING PLANT
INCO Engineering (Prague), provides not only deliveries of new shaft hoisting machines, but also reconstructs and upgrades operating machines. Pneumatic braking devices stay original but they are switched to new system SISTONIC PR6B. As example delivery volume is given for double-drum hoists, having two braking drives, for which separate control of brakes for fixed and dismountable drums is necessary (when reloading hauling units in case of usage of double action at different levels).
