The Gantner GN 923… and GN 924… handwheel range is made of plastic-coated aluminium and is available either as spoked handwheels or as disk handwheels. A removable plastic lid covers the fixing elements such as washers or recessed or protruding shafts. The GN 923 and GN 924 models are available with or without revolving handle. The GN 923.3, GN 923.7, GN 924.3 and GN 924.7 models are used when the revolving handle is not to jut out temporarily. In the working position, the folding handles of the GN 923.3 and GN 924.4 handwheels are locked in a conical bore. To fold back, the handle must first be pulled out of the cone in axial direction. A pressure spring holds the folding handle in both positions. It automatically engages again when folded out.
