HELSINKI, Finland– Cargotec has introduced electrically-driven versions of its proven range of offshore MacGregor anchor handling/ towing winches (eAHT).
The eAHT series comprises winches with line pulls ranging from 200 to 600 metric tons (220 to 661 tons), with an initial speed up to 25 m/min and a brake holding capacity up to 800 metric tons (882 tons).
Each winch is available in double- or triple-drum configuration. The extended shaft connections at both ends of the winch are suitable for fitting chain wheels to handle chains ranging from 76 to 160 mm diameter.
The winches are driven by an AC variable frequency electric motor through an enclosed helical bevel gearbox. They also feature a freshwater-cooled hydraulic or pneumatic disc brake system allowing smooth changing between operational speed modes, from static to dynamic and during dynamic-lowering operations. They also have a regenerative multi-drive system.
The winches are equipped with independent electro-hydraulically or fully electrically-driven spooling devices. All control features, including the length, speed and tension-monitoring system, are incorporated in one or two touch screens and remote control panels.
Francis Wong, Cargotec’s sales director for offshore winch solutions, said: "This new series of electrically-driven winches inherits the best characteristics of our proven designs. This ensures safe operations, easy maintenance, and also combines improved operability with a low environmental impact, reduced power consumption, and low installation costs."
