A handwheel is
a convenient solution for manually operating a jack when using machine
screw jacks in intermittent positioning applications. Handwheels
are available in a range of diameters from 4 to 10 inches and can
be adapted for use on jacks from the MJ series up to the 20 ton
capacity model. These handwheels are made from cast aluminum and
include a removable freewheeling handle.
NOTE: Handwheels do not include a brake. Handwheels
are not recommended for use with ball screw jacks. When using handwheels
with a jack that can backdrive (12:1 and lower) an additional locking
mechanism may be required to prevent “creep”.
