GN 521.3 (VDS+IR) Handwheel, Plastic, Retractable Handle.
The shape, design and quality of this disc handwheel meets high expectations, whilst being very competitively priced.
The handle in these safety handwheels is locked into position, in a conical bore, during use, or into its recess when at rest. A pressure spring holds the handle in either rest position, and cannot be accidentally knocked. When the handle is used in the operating position it is firmly anchored. To fold it in, it has to be pulled out of the rest position parallel to the shaft. When swung back out, into the operation position, it will automatically engage.
The cover conceals clamping elements, e.g. countershaft pulleys, as well as protruding and recessed shafts. For mounting, the cover is pushed in by hand. For dismantling, the cover can be raised and taken off by applying moderate pressure in the rim of the cover.
