Rubber Tyred Gantry Cranes (RTG)

Proven RTG solutions

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.

Advantages at a glance:

  • Cost-effective solutions due to lower energy consumption
  • Better efficiency in comparison to diesel generators
  • Protection against volatile oil prices
  • No time loss due to refuelling
  • Reduced maintenance downtimes
  • Significant reduction in CO2 emissions
  • Environmentally friendly due to the elimination of various
