CAT The CAT (➔ figure 9) modular design concept makes it easy to interchange critical components such as motors, gears, screws, attachments, etc. Custom built actuators are easily and cost efficiently built from standard parts. The CAT range flexibility makes it suitable for an infinite number of applications. Benefits: ● Small ● Robust ● Highly efficient ● Maintenance-free
