| Scope: | Design, manufacture and supply of 5 x 12t take-up winches 1 x 16t take-up winch + corresponding capacity take-up sheaves | |
The winch system is used to position the counterweight within the acceptable travel limits in the take-up tower. Upper and lower end of normal travel limit switches are activated when the counterweight moves past them. Once activated, the winch automatically operates for a preset period of time and return the counterweight towards the centre of travel. Operation of an upper and lower over-travel limits will allow the winch system to initiate a conveyor quick stop sequence if activated. The winch is fitted with a fail safe spring, electrically released brake motor, which will allow the counterweight to be held in position in the event of a power failure. Other system protection and control components include motor protection and fault monitoring, travel limit switches for the counterweight travel, over-travel limit switches for the counterweight travel, emergency stop switch, slack rope detector system and load ratchet for complete mechanical isolation.
