Rotork has been working with BAE Systems to upgrade a collection of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A sequence of A-range actuators had reached the top of their operational life after lengthy service in a difficult surroundings. BAE Systems wanted to retain all the benefits of electric actuators, so IQ3 actuators were chosen. These needed to be specially tailored by Rotork to beat problems around confined areas and tough access.
IQ3 actuators and IS gearboxes have been mechanically tailored so that both actuator and gearbox might be operated by hand without getting into the confined space. Rotork designed particular hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the need for confined house entry.
Actuators throughout the IQ range are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. Elusive have an advanced twin stacked display with configurable data logger performance, and an absolute place sensor supplies reliability and accuracy.
