MacGregor introduces the next generation of variable frequency drive (VFD) electric cranes.
To date, the company has delivered more than 500 electric cranes since 2007, with electric motor and drive system technology evolving significantly during this time. These developments have enabled the winch design, motor efficiency and cooling system to be further improved. As a result, the new generation crane is 15% more efficient than the first generation design and up to 50% more efficient compared to the traditional closed-loop hydraulic design.
According to the manufacturer, VFD benefits include:
Electric drives are available for all merchant cranes in the MacGregor portfolio, including port, bulker, container, multi-purpose and heavy lift cranes.
In addition, all electric cranes can be connected to the OnWatch Scout condition-based monitoring and predictive maintenance service, with the option to include several automation functionalities such as Auto-Drive and Auto-Tandem.
