Electric Multipurpose Cranes
An electric-drive version of the GL crane
Multipurpose Crane - Electric (GLE)
The MacGregor electric drive multipurpose crane (type GLE) is the first choice for highly efficient cargo operation. The GLE is the electric-drive version of the GL crane. Both the electric and electro-hydraulic cranes have the same safe working loads (SWL) and outreaches.
>GLE crane designs are based on MacGregor’s lengthy experience and backed-up by unrivalled global service support and a proven track record of more than 13,000 crane deliveries worldwide over the past 50 years.
The crane offers multiple benefits
- Up to 50% lower energy consumption (especially during standby mode)
- Up to 50% lower fuel consumption
- Potential savings in capital expenditure through reduced generator size
- Smaller electric cables and no oil filling
- Superior cargo handling efficiency due to higher speeds and precision control, reducing time in port
- Increased operator & crew comfort through significantly reduced noise levels
- Lower maintenance costs without the need to change oil, oil filters, and hoses
- A sustainable choice that removes the risk of oil leakage
- Up to SWL 25t - 100t

Generation 2 Drive System
Like all MacGregor electric cranes, the GLE series is built upon the Generation 2 variable frequency drive (VFD) design.
The advanced design is based on the latest generation of water-cooled electric motors and inverters. Also, it includes a direct motor connection for further improved power efficiency due to less power transmission losses.
Crane Control System
The MacGregor control system ensures smooth, fast and stepless crane control, with hoisting, luffing and slewing motions independent of each other. This means that at their maximum capacity, GLE cranes can operate at full speed using all three movements at the same time.
The in-house system development allows individual adjustment possibilities and includes monitoring and diagnostic functions.
Option for OnWatch Scout
OnWatch Scout increases the flow of information and moves support from a reactive to proactive mode, with operational data streamed directly from the vessel, monitored, analysed, and used to provide guidance on performance.
