Enhanced RTG range marks 25th anniversary for Liebherr

Designed for efficiency, sustainability and performance, Liebherr states the RTGs are backed by advanced modelling software, thereby helping ports and terminals choose the right solution to optimise operations and cut emissions.

In what the company describes as its “next step in its RTG evolution,” Liebherr is marking its 25^th anniversary of providing RTGs by offering a range of five models:

• RTG-CB (Electric, Conductor Bar) – A fully electric RTG with a continuous power supply, requiring fixed conductor bar infrastructure.
• ERTG-CRD (Electric, Cable Reeling Drum) – A fully electric RTG with a flexible power feed, utilising a reeling drum for cable management.
• RTG-HC (Hybrid, Capacitor) – A hybrid RTG utilising super-capacitors for energy recovery in combination with a smaller diesel generator. Offers the lowest capex investment and fastest pay-back period for a hybrid system.
• RTG-HB (Hybrid, Battery) – A diesel-electric hybrid RTG utilising battery energy storage, designed for optimal fuel saving and emissions reductions.
• RTG-VSG (Variable Speed Genset) – A fuel-efficient diesel RTG with optimised performance, reducing fuel consumption compared to standard diesel RTGs.

The company provided an explanation of its strategy in the provision of this equipment, by stating: “Designed to meet the ever-changing demands of terminal operations, the next generation of Liebherr RTGs delivers optimised efficiency, reduced emissions, and superior performance, ensuring operators can easily select the ideal solution for their operational needs.”

Charlie McCarthy, MD Engineering at Liebherr Container Cranes says that the RTG range allows customers to advance environmental ambitions and plan for a net zero future: “Our electric RTGs operate with zero local emissions while our hybrid models deliver exceptional performance alongside significant reductions in emissions, running costs and maintenance. Additionally, our variable speed generator RTGs provide exceptional performance and a substantial decrease in emissions compared to traditional diesel machines. Liebherr’s proprietary software enables advanced simulations and energy modelling, predicting fuel and energy consumption, for various power system configurations based on clients’ specific operational scenarios. This allows us to accurately simulate customers’ operations to explore and optimise alternative operating scenarios. Furthermore, by accommodating local and regional economic factors, we can conduct comprehensive economic assessments to identify the optimal machine for a customer’s setup, considering both cost and performance.”

Liebherr notes there has been “exceptional progress of the past quarter century” with respect to advances in automation, energy efficiency and digital integration, but looking ahead the company is expecting the pace of change to continue for the next 25 years, with even greater potential for innovation.
