The WINDER CONTROLS SB1-2 brake system is a two channel, intelligent, integrated, electrohydraulic brake controller with inbuilt redundancy and designed for use with disc brake systems on mine winders.
The system provides closed loop, controlled deceleration under safety or emergency braking to ensure that the conveyance is safely brought to rest under all normal conditions of load and direction of travel without introducing rope slip.
The system consists of two independent hydraulic channels, each with inbuilt redundant control valves. This ensures that the likelihood of the brakes failing to apply is extremely low. Hydraulic oil pressure is provided by an operating and a standby pump with an independent off line filtration and cooling circuit pump. Control is provided by a PLC controlling both hydraulic channels. A back up battery provides power to ensure that all design mechanical braking functions are maintained in the event of a power failure.
