Manual Screw Jack is made up of hand wheel or hand crank and a
worm gear screw jack.
It is suitable for applications where electricity or power
generators is inconvenient or dangerous, light weight, low duty
cycle, low target cost and short travel length.
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 manual
screw jack with high speed,a bevel gear jack is the best
choice.
Manual screw jack is widely used for crank table.
