2.Manual Screw Jack Features
The hand crank screw jack has a
disadvantage that is the travel speed is slow and the maximum travel
length of the handwheel or handwheel per revolution is 1 to 1.5 mm. However,
manual bevel gear jacks are the ideal solution for slower walking
speeds with internal bevel helical gear pairs up to 12mm stroke length
with one handwheel or crank per revolution. When you need a hand crank screw jack with high speed,a bevel gear jack is the best choice.
