Determination of type Direction of rotation Translating screw (upright) Rotating screw with lifting nut (upright) Translating screw (inverted) Note: For types HN/HQ and HK spindle must be held to prevent rotation. Rotating screw with lifting nut (inverted) For types HNL/HQL and HKL lifting nut must be held to prevent rotation.

Selection of jacks Symbols used: F = Force (N) (1 tonne = 10 000 N) v = Lifting speed (mm/min) s = Pitch of lifting screw (mm) n = input speed (rpm) i = Ratio of worm gear set ED = Intermittence factor (%) Pd = Running power of screw jack (kW) Ps = Starting power of screw jack (kW) PED = Thermal power (kW) PMnom = Nominal motor power (kW) PMst = Starting power of motor (kW) PMax = Max allowable input power of screw jack (kW) nd = Running efficiency of screw jack r|s = Starting efficiency of screw jack To calculate a screw jack you must at least know the force (F) to be moved and the...

haaconGuide to select single screw jack arrangements Single screw jack Load: 30 kN compression Stroke: 500 mm Loadcase: Euler II Intermittence factor: 15 min/hour Lifting speed: 415 mm/min Ambient temperature: 25° C 1. Select a screw jack where the nominal force is larger than the required force from table below: Load 30kN -> HQ 50: Max capacity for HQ 50 is 50 kN > 30 kN. 3. Selection of one screw jack. Calculate the running power (Pd) and starting power (Ps). These are stated in tables or can be calculated as follows: Pd = (F x v)/(r|d x 6 x 101 2 3) = (30 x...

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...
