Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve a sequence 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).
Uncharted of A-range actuators had reached the tip of their operational life after lengthy service in a challenging environment. BAE Systems wanted to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These needed to be specially adapted by Rotork to overcome problems round confined areas and troublesome access.
IQ3 actuators and IS gearboxes had been mechanically adapted in order that each actuator and gearbox could presumably be operated by hand without entering the confined space. Rotork designed particular hand auto levers and through drive mechanisms for the actuator and gearbox to remove the need for confined house entry.
Actuators within the IQ range are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. Simple as ABC have a complicated dual stacked show with configurable data logger functionality, and an absolute place sensor offers reliability and accuracy.
