MacGregor's safety system includes the well-proven and very reliable CC 2000 control system.
- The primary software-based safety system is connected to load cells, encoders and transmitters and also has a degree of redundancy.
- In case of encoder failure when connected to the software-based system, the crane can still be operated in ’failsafe mode’ with the conventional
safety system activated. In this mode the crane’s operating speed is reduced. - The safety system includes a display located in the cabin, the ’MacHeavyvisor’. It gives the driver information including the current hook load, the outreach, hoisting speed, and heel angle. The display also has a heel warning.
- Information shown on the display for each crane can be transmitted via the slip ring device, through a cable, to a PC in, for example, the ship’s office or the bridge. This makes it easy for the chief officer to have excellent control of a team lift operation, for example.
- In the crane cabin there is a crane computer, which graphically presents information from the CC 2000 crane control system on the display.
- The crane computer is also used for logging load.
