Enhanced Gimbal Assembly Description
The Enhanced (Unibody) Gimbal (Figure 4) is constructed with high-strength Aluminum Alloy and
does provide an unrestricted service life limit as with the other configurations. The Enhanced Gimbal
integrates reinforcement features such as a one-piece arm, ribbed bends and a flared design to
provide structural integrity. Precision Gearboxes augment performance by allowing backlash of less
than 1°, adding a sealed enclosure, dry lube treated gears, and a precise fit end cap. The Enhanced
Gimbal high-speed motors offer a slew rate of up to 18° per second. Adjustable Elevation stop blocks
are incorporated to improve ease of moving of upper and lower elevation limits in 2° increments.
Elevation stop block shown is for illustration purposes and may vary from current design. The
enhanced Gimbal is intended to be backwards compatible to all SX-16 Nightsun® Searchlight
systems.
