ELESA original design 
EN 522.6 two spoked handwheels are designed for applications where it is necessary for the handle to return back to starting position after operation for safety reasons or lack of space.
These handwheels have the distinguishing features where the handle and the retracting mechanism are completely encased within the rim of the wheel.
In the operating position, the handle is secured by a taper detent. To fold it down, it is drawn out from the tapered recess. A compression spring secures the handle in either position.
Ergonomically shaped rim for a safer and more comfortable grip.
Handle pivots freely during operation; a system of coaxial bushings compensates return spring load.
Resistant to solvents, oils, grease and other chemical agents.
Due to the materials used, these handwheels are especially suitable for use in corrosive atmospheres or in areas which must be wet cleaned. In particular, the FDA certified plastic materials permit use in the food industry.

The connection between the operating element and the shaft is often made by a cross pin or a grub screw. As a result, the user is faced with relatively high assembly costs since cross holes on operating elements are usually not readily available. Components with cross holes according to GN 110 are not only manufactured and supplied at very competitive prices but there is also no need for time-consuming design drawings. However, the geometrical shape of some operating elements does not allow the use of this standard. The d2 pin hole is intended for use with a spring pin. |
