Overview
A spinner hanger is a rotating suspension system used in sandblasting and shotblasting booths to hold, rotate and index parts during abrasive cleaning. It allows continuous, even coverage on complex shapes by spinning the workpiece while blast guns remain stationary. Spinner hangers suit production lines, offer adjustable speed and indexing, and integrate with reclaim systems, dust collectors and conveyors for efficient, repeatable surface preparation in manufacturing and restoration.
FAQ
What should I inspect when buying a used spinner hanger?
Check bearing condition, drive motor and gearbox, welds on hangers, rotation smoothness, indexing accuracy, control panel function, and signs of corrosion or wear on hooks and spindles.
How do I confirm a spinner hanger matches my parts and line?
Verify maximum load capacity, hook spacing and diameter, rotation speed range, indexing options, part dimensions, and compatibility with your conveyor and reclaim system.
What are key shipping considerations for a spinner hanger?
Measure overall dimensions, weight, and lifting points. Secure rotating components, protect controls and bearings, and choose a carrier experienced with industrial booths. Crating and removal of fragile items reduce transit damage.
What electrical and installation requirements should I expect?
Confirm motor voltage, phase and starter type, control voltage, grounding, and space for drives and gearboxes. Plan for mounting points, alignment with conveyors, and integration with dust collectors and reclaim piping.
What regular maintenance does a spinner hanger need?
Lubricate bearings and gearboxes per manufacturer schedule, inspect hooks and welds, check motor brush or coupling wear, test indexing and brakes, and clean abrasive buildup to prevent imbalance.
Which wear parts should I keep as spares?
Keep spare bearings, seals, drive belts or chains, gearbox oil, hooks or hangers, electrical relays/contactors, and any proprietary spindle or indexing components.
