How to find the right Crank Handles AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Crank Handles
- Bore and drive type
- Match the shaft diameter and drive (round with set screw, keyway, D-flat or square) exactly. A crank that slips on its shaft cannot transmit torque.
- Crank radius
- Choose a longer radius for more leverage and a shorter radius for faster turning. Radius sets the trade-off between effort and speed.
- Grip type
- Choose a revolving grip for continuous cranking and a fold-away grip where the handle must not protrude or spin into people. A fixed grip chafes the hand during long cranking, and a protruding grip is a snag hazard.
- Material
- Use cast iron, steel or stainless for heavy loads, and technopolymer for light adjustment wheels. Plastic arms flex under high torque.
Brands that matter
- Elesa+Ganter: Crank handles and handwheels in plastic and metal with standard bores.
- Kipp: Crank handles with folding grips.
- J.W. Winco: Inch and metric cranks with dimension drawings.
- Reid Supply: Stocks crank handles and handwheels.
What to avoid
- Cranks listed without bore size or drive type.
- Fixed protruding grips on shafts that can be back-driven, where the spinning handle is a strike hazard.
