Functioning of adjustable hand levers
Applications for hand levers
- Machine and plant construction: Wherever the position of components must be changed quickly by hand, hand levers or clamping levers are a useful standard part. For special requirements, such as controlling mechanical functions on a machine, gear levers and control levers are also available.
- Food processing equipment and medical technology (hygienic and sanitary areas): For the challenging areas of food processing equipment, medical technology, and the pharmaceutical industry, Winco developed special hand levers in “hygienic design”. These DGUV-tested hand levers are made of easy-to-clean material with a very plain surface and can be fastened without dead space.
- Other applications: A hand lever is generally the perfect solution wherever frequent manual adjustment and clamping are required. The applications are extremely diverse: Stage equipment, film production, photo studios, and sports equipment are just a small selection of possible uses for these practical and reasonably priced standard parts.
- Special requirements for increased safety: Safety tension levers can only be released when the lever hub is pressed down. This effectively prevents accidental operation and unintended releasing of the tension lever.
