Description
The speed limiter of mine hoist engines of OSPM is intended for protection against emergency reraising of vessels and speeding of the hoist engines established on a surface with rise height to 2000 meters.
The OSPM limiter carries out disconnection of a chain of protection at achievement by a hoist engine of speed which is equal the set protective tachogram on sites of a way of dispersal, steady running, delay, a dotyagivaniye on a rerise height site.
