Manually Operate Screw Jack
Manually Operate Screw Jack detailed informations:A hand wheel is a convenient solution for manual operated a screw jack or screw jack systems. When using screw jacks in intermittent positioning applications. Hand wheels are available in a range of diameters from 5 to 12 inches and customized follow clients' need.Hand Wheels do not include a brake. Hand wheels are not recommended for use with ball screw jacks. When using hand wheel with a screw jack that can backdrive an additional locking mechanism may be required to prevent "creep".For precise position display, a range of digital counters are available for use with screw jacks. These digital counters measure the rotation of the input shaft and display corresponding position in a counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different jack ratios, lifting screw pitch and travel distances.Human Force Calculation Formulas:HF=(G*P)/(R1*R2)HF:human force (kgs)G :working load (kgs)P :screw pitch (mm)R1:gear ratio R2:hand wheel radiusExample, working load 50 kgs,the fast speed,manual operated.Check specification table, 50 kgs with manual operated, use the smallest model RN-0.5T(pitch=5mm) enough. Fast speed1/5.Usually,RN-0.5T jack with 5"(125) diameter hand wheel. How much about human force?HF=(50*5)/(5*62.5)=0.8 kgs.Every model has three speed ratios.RN-0.5T,RN-1T,RN-2T,RN-3T,RN-5T,RN-10T and RN-15TFast speed: 1 turn 1 mm travelsMid speed: 1 turn 0.5 mm travelsLow speed: 1 turn 0.25 mm travelsThe larger models screw jacks are not suitable for manual operated.Did Projects:Sluice gate in hydroelectric dam,Powered straighteners,Precision levelers,Solar tracking jack systems,Large satellite dish antenna movements,Slitting line,Roll forming machines,Tunnel freezer systems,Oven lifters,Vacuum furnace lid lifters,Conveyor lifts,Air dampers,Theatre stages,Glass charging machines,Steel manufacturing mills,Cold/Hot rolling mills,All tube mills.

Q: What is rotating screw jack? A: A lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate, but not translate. A traveling nut, attached to the load, is driven by
