Description
harmonic drive pedestals, the HD-40 is designed to support solid reflectors up to 2.4 meters in winds of 65 MPH. High output torque with low backlash is accomplished with the use of planocentric gearboxes and brushless DC motors. The rugged gearboxes use built-in angular ball bearing construction, which improves the ability to support external loads, increases moment rigidity, and increases maximum allowable moment, resulting in increased reliability and a reduction in maintenance.
