The RAT System
Loxystem introduces a new concept that will increase productivity and improve safety of container handling in port:
The RAT System - Remote Automatic Twistlock
Controlled by remote and with built in safety system, containers can now be dispatched efficiently and safely. Prior to each container move the system verifies the status of each twistlock.
- Unlocking of twistlocks by remote control
- Containers safely secured on deck with twistlocks confirmed in a locked position
- More container moves per hour possible - means faster vessel turn-around
- Improved safety for workers
- Vertical tandem lift capability offers safe lifts with built in system check
- By remotely writing and reading information into the twistlocks they can convey information from port to port such as container ID and port of destination
RATs - Key Customer Benefits
- Discharging of containers immediately upon arrival of the vessel without the need to manually unlock twistlocks
- Faster turn-around
- Lower labour cost
- Offers improved safety with positive confirmation of locked or unlocked state
- Safe handling
- Containers fastened securely on deck
- Only the twistlocks of a container about to be lifted is unlocked, all other containers remain secured
- Vertical tandem lift capability
- Remote control improves efficiency for vertical tandem lifts
- Safe operation since locked state confirmed prior to lift
- Automatic control that twistlocks have valid lifting tool certification
- Offers a mode to convey information from point of loading to discharge with the systems capability to write and read container information into the twistlock.
