As part of its mission to support customers with more environmentally sustainable products and solutions, deck equipment specialist MacGregor has introduced a fully electrically driven heavy lift crane (HCE) as a new member of the heavy lift crane family.

The HCE is a result of combining MacGregor and NMF’s extensive experience in the heavy lift industry (Macgregor acquired the NMF crane brand with its 2019 takeover of TTS). Both design philosophies were examined in detail, with the best elements then combined together to develop an industry leading design which covers lifting capacity up to SWL 1000 tonnes.

Key benefits are most clearly evident in the weight and drive system. By combining NMF crane house design principles with MacGregor high tensile steel experience, the weight of the HCE is significantly reduced. This has a major advantage for the pedestal size and cargo capacity of the vessel.

The new MacGregor Variable Frequency Drive (VFD) system improves HCE efficiency by up to 50% compared to the traditional closed-loop hydraulic design. In addition, power consumption can be as much as 80% lower during standby time for lashing and securing. General VFD advantages including potential savings in capital expenditure, superior cargo handling and lower maintenance costs without the need to change oil, oil filters and hoses equally apply to the HCE.

Reliability and safety have also been improved through redundant power supply units, which enable high system availability and fault tolerance of critical components, and the use of additional brakes.

The HCE 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.
