Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve a collection of A-range actuators to IQ3 actuators which function penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
Stunning of A-range actuators had reached the top of their operational life after long service in a challenging surroundings. BAE Systems needed to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These had to be specially adapted by Rotork to overcome problems round confined areas and difficult access.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that each actuator and gearbox might be manually operated without coming into the confined house. Rotork designed particular hand auto levers and through drive mechanisms for the actuator and gearbox to remove the necessity for confined house entry.
Actuators inside the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have an advanced dual stacked display with configurable information logger functionality, and an absolute place sensor offers reliability and accuracy.
