Flotron’s Small Foot Print (SFP) 1000 series Rotation Fixtures are a higher capacity, more compact version of the 1000 series where floor space is a premium. The SFP-1000 series includes additional features and options; lift points above the CG capable of lifting the Flotron (with the payload integrated), one inch of axial float on the non-gearbox side trunnion to ease payload integration, flat leg design to lower the rotation centerline height without sacrificing available payload swing radius, lighter weight to ease maneuverability, elimination of single failure points for launch site compatibility, pillow block bearing bushings on the non-gearbox-side trunnion, as well as an option for a cordless hand drill to rotate the gearbox. They are supplied with a heavy-duty, hollow shaft, stairstep resistant gearboxes to handle large, off-center loads that may occur during assembly of the mounted payload.

SFP-847 Data Sheet
The Model SFP-847-J0-P1-INDS15-P12-T3 shown below is typical and representative of the SFP-847 Models. For more information on specifying a holding fixture, see the SFP-800 SERIES OPTION page and SFP-800 SERIES CREATING A MODEL NUMBER pdf.
- The maximum distance between mounting interfaces is directly related to the main beam length. Specify the distance between mounting interfaces to be at or slightly longer than the length of the payload. The end frames can be adjusted inward to accommodate shorter length payloads, however the main beam(s) protruding beyond the end frames may result in a trip hazard. For more information see the SFP-800 SERIES OPTIONS page and SFP-800 SERIES CREATING A MODEL NUMBER pdf.

Flotron’s satellite mobile platforms are designed to support satellites in the vertical orientation, i.e. when the longitudinal axis of the satellite is perpendicular to the floor. The payload separation plane is low to the floor to minimize the required hook height when integrating the space vehicle with the platform interface using an overhead crane. The platform provides a working area for technicians to gain ergonomic access to the spacecraft during assembly, integration and test operations. Leveling jacks allow the technician to level the unit on uneven terrain. The satellite platform is designed to consider ergonomics during intra-facility transportation of the space vehicle. Caster wheel material has been specified to maximize rollability and both a push bar and a tow bar have been incorporated to provide options for maneuvering the loaded satellite mobile platform.

Flotron’s Mobile Two Axis Positioner (MTAP-4000) allows for ergonomic tilting and rotation of the spaceflight hardware while being supported in a cantilevered configuration. The positioner can tilt 90 degrees from horizontal to vertical, or vice versa. The positioner can also rotate the hardware 360 degrees along its longitudinal axis utilizing a two axis UL approved control system. Over-travel limit switches have been incorporated at both ends of the tilt range. The interface has through access which may support propulsion integration or wiring.
The cart can support a 4,000 lb payload with CG located at 60” from the mounting interface and 5” from the rotation centerline considering a ½G side load and 1 G vertical load and SFy = 3 / SFu = 5. Two mechanically synchronized low backlash, non-back driving gearboxes are used for tilting, each of which is capable of supporting the rated moment. The H-frame design provides ergonomic access from either end of the fixture. The maximum available swing envelope is 110”. There are forklift tube pockets for lifting the empty fixture. The positioner is compatible in a Class 1K (ISO 6) clean room.
Flotron’s Mechanically Synchronized Lift/Rotate (MSL-2000) fixture has a load rating of 2,000 lbs at 3.75” maximum eccentricity considering SFy = 3 and SFu = 5 in addition to a simultaneous dynamic loading condition of ½ G side load and 1G vertical load.
Mechanically synchronized ACME screw lift jacks raise the carriages with bearing blocks along precision linear guide bearings rails through a 24” range. Hard stops limit the travel to prevent damage to the payload and a safety clutch has been incorporated to prevent damage to the power transmission. A +/- 1.0” axial float on the non-gearbox-side trunnion provides interface distance adjustment and allows for ergonomic payload integration and removal. Hard mounted battery powered drill drive lift/lower standard.
