Rotork assists BAE Systems in naval base actuator upgrades

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 collection of A-range actuators had reached the top of their operational life after long service in a challenging setting. เกจอาร์กอน wanted to retain all the advantages of electric actuators, so IQ3 actuators had been chosen. These had to be specifically adapted by Rotork to overcome problems around confined spaces and difficult access.
IQ3 actuators and IS gearboxes have been mechanically adapted so that each actuator and gearbox could be operated by hand without getting into the confined house. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to eliminate the need for confined space access.
Actuators within the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have an advanced twin stacked show with configurable knowledge logger performance, and an absolute position sensor offers reliability and accuracy.
