Flotron’s Dual Support Cradles (DSC) are designed to turn a standard rotation fixture into a dual axis of rotation fixture. The DSC is for cantilevered payloads that require both tilting and 360° rotation. There are different capacity cradles for different payload weights and the larger cradle features the option to have gearbox driven rotation on the secondary axis of rotation. The DSC-P1 was designed to be used with Flotron’s XD739, XD747, or SFP-645 series dual support fixtures. The DSC-P2 and DSC-G2 were designed to be used with Flotron’s SFP-759, SFP-853, or SFP-862 series dual support fixtures. The cradles can be used with other rotation fixtures if the capacity is rated high enough and swing clearance is sufficient. The cradles have been optimized for both high strength and low weight with advanced FEA software. Custom length cradles are available upon request in 20” increments for payloads that require more (or less) swing radius clearance than the standard. The load rating may be lower for longer cradles than standard.

(Hand Turned/Pinned Interface)
Load Rating: 2,500 lbs Cantilevered 30” (See dimensional drawing sheets 3-6 for load curves)
Payload Max Swing Radius: 59”
Max Torque (Secondary Axis): 10,000 in-lbs
Product Features
- Safety Factor: 3 for Yield & 5 for Ultimate
- Rated Load Capacity: Dynamic, 0″ to 4″ eccentricity: 2,500 lbs. (1,134 kg.) Cantilevered 30” (762mm)
- Operating Temperature: +32 to +104 °F (0 to +40 °C). Contact factory for special applications with extended operating temperatures.
