Competence in lifting technology Guide to select multiple screw jack arrangements Lauter ton drive Screw jack arrangements Pre-step Helical Gear 1. Running power consummation for each screw jack = 0.77 kW according to calculation above. Starting power consummation for each screw jack = 1.48 kW according to calculation above. 2. Add the power- and starting consummation for each screw jack to get the total power- and starting consummation power Px and Pxst. For arrangement with 4 screw jacks: Px = 4 x 0.77 = 3.08 kW Pxst = 4 x 1.48 = 5.92 kW 3. Take consideration to the efficiency to the connection...
