1969 Mr. Enzfelder established a job shop in Vienna. Equipped with some machinery, the Enzfelder Company manufactured machine parts according to drawings. Within one year the number of employees rose to 3. The Enzfelder company started manufacturing threaded spindles and nuts according to drawings. Then the range of manufacturing was enlarged by toothed wheels, screw wheels and endless screws according to drawings. 1974 The company including the complete manufacture was relocated to Enzesfeld. 1975 The manufacture of spindle gears was launched. The company’s experience in the manufacture of trapezoid-threaded...

Product as delivered: enclosed Safty nuts Connected with the loaded traveling nut via driving pins, the locking nut runs at idle. As the threads in the traveling nut wear It approaches the idling, unloaded and therefore unworn safety nut. The wear is ascertained by checking the slot H. When the table entry H has declined by half the traveling nut must be replaced! The visual check Df the slot H can be automated by integrating an automatic disconnecting...

ENZFELDER GMBH Power transmission- and lifting engineering Mounting and Maintenance Instructionsfor Spindle gear BG2,5 - BG150Mounting Spindle gears must be mounted in true alignment on a flat surface which must be so stiff that it can assume the maximal load without oscillations or deformations. The alignment and correct positioning of the spindle gear must be done very carefully as no side forces should act on spindle and guide rings. In lifting systems the spindle noses (in case of the basic type) or the traveling nuts (in case of the traveling nut type) must lie level with each other before...
