Rubber Tyred Gantry Cranes (RTG) are used in particular for efficient stacking of standard containers. Since they are mobile, RTGs were originally powered by diesel generator systems. In recent years, there has been a clear trend towards the electrification of RTGs. Therefore, motorized cable reels are important components when it comes to retrofitting RTG cranes worldwide with the aim of significantly reducing overall fuel consumption.
Shutting down diesel generators is not only the better environmental solution, but may be a growing economic argument for port operators.
