A high-performance unit specially designed for applications where multiple payloads are needed on a single mast. Its small and robust design make it ideal for mobile applications. Essentially unit acts as a static mast extension where an additional payload can be placed on top. Payloads of the Twister unit, such as radar, have endless rotation on pan axis and a range of at least ±20˚ on tilt axis. Its static top mount can carry up to 120 kg of additional load. This design is used for a top mounted multi- sensor with a separate pan-tilt unit. Twister pan-tilt has a wide speed range and an integrated brake system when powered off. With positioning system placed on the output shaft precision it promises uncompromised accuracy.
